| Aluminum Clad Sliding Patio Doors

Door Type Note: Arrows shown in the door type drawings indicate the direction each operating panel slides. Single slide doors can be configured with different active panel locations, and center panels may be able to slide in either direction depending on the selected layout.

• Single slide layouts work well for standard patio, deck, and yard access openings.
• Double slide layouts may be reviewed where more flexible panel operation is desired.
• Bi-parting layouts create a centered opening and balanced appearance.
• Telescoping layouts can create a wider clear opening than a standard two-panel slider.
• Bi-parting telescoping layouts are designed for larger openings and stronger indoor/outdoor living connections.
• Stationary or sidelite panels may be reviewed where the design calls for additional glass area without every panel operating.
• Unequal panel sizing may be reviewed where available to better match the opening, traffic flow, or design intent.

Sliding patio door type should be selected with the full project in mind. The number of panels, active panel location, operation direction, rail style, glass package, screen system, hardware, clear opening, delivery access, and installation conditions can all affect the final configuration.

Maximum sizes, large-opening configurations, unequal panel sizing, French Rail availability, screen options, and hardware options should be reviewed before quoting or ordering.

Color Note: Digital color swatches can vary by screen, lighting, photography, and device settings. Actual exterior clad colors and interior wood finishes should be confirmed with physical samples before final color selection whenever color match is important.

• Actual colors may vary from digital swatches.
• Physical color samples should be reviewed before final selection when color accuracy is important.
• Exterior clad color should be reviewed with siding, trim, roofing, exterior doors, and surrounding window colors.
• Interior wood finish should be reviewed with trim, flooring, cabinetry, wall color, and hardware finish selections.
• Estate Colors may be reviewed when standard exterior colors do not meet the project design requirements.
• Sliding patio door colors can be coordinated with Casco Aluminum-Clad Windows, Aluminum-Clad Casement Windows, Aluminum-Clad Double-Hung Windows, and Casco Aluminum-Clad Swing Patio Doors.

Glass Selection Note: The base glass configuration is clear insulated glass with air fill. LoĒ glass packages are typically required when a project must meet a specific local energy code requirement, U-factor requirement, SHGC requirement, or performance target. Customers and project teams are responsible for confirming applicable energy requirements before purchasing Casco aluminum-clad sliding patio doors.

Base Glass Configuration

The base glass configuration for Casco Aluminum-Clad Sliding Patio Doors is clear insulated glass with air fill. This base configuration may be used when the project does not require a specific Low-E package and the applicable energy requirements allow it.

Clear glass allows strong visible light, but it does not provide the same solar control, UV protection, or U-factor performance as Low-E glass packages. When a project has a local energy code requirement or a specific U-factor, SHGC, or performance target, a Low-E glass package is typically required.

• U-factor measures heat flow through the window or door assembly. A lower U-factor means better resistance to heat loss.
• SHGC measures how much solar radiation enters as heat. A lower SHGC helps reduce solar heat gain.
• Visible Transmittance measures how much visible light passes through the glass. A higher visible transmittance means more daylight.
• UV transmission relates to fading protection. Lower UV transmission helps reduce fading potential for furniture, flooring, fabrics, artwork, and interior finishes.
• Glare control reduces harsh visible light in direct sun conditions.
• Privacy control can be handled through obscure glass or Blink blinds-between-glass depending on whether the project needs permanent privacy or integrated blind operation.

Laminated Glass

Laminated glass is available for Casco aluminum-clad sliding patio doors. Laminated glass can be ordered with the same Cardinal LoĒ glass options when the project requires laminated glass along with a specific Low-E package.

Laminated glass is commonly reviewed when the project requires added safety, sound control, security considerations, impact resistance considerations, or project-specific glass requirements. The correct laminated glass configuration should be reviewed with the required Cardinal LoĒ coating, energy performance requirements, unit size, project location, and applicable code requirements before ordering.

Obscure Glass

Obscure glass is available for sliding patio doors. It is commonly used in areas where privacy is needed while still allowing light into the room.

Blink Blinds-Between-Glass

Blink blinds-between-glass options are available where size, product configuration, glass package, and project requirements allow. These options place the blind inside the insulated glass unit, helping protect the blind from dust, damage, and exposed cords.

Blinds-between-glass options must be reviewed for available sizes, glass type, Low-E requirements, operation type, warranty, lead time, and the project’s required energy performance before ordering.

• Clear insulated glass with air fill is the base glass configuration.
• LoĒ options are typically required when a project must meet a specific local energy code requirement or performance target.
• Quad LoĒ-452+ with Neat+ is commonly used for strong solar control, neutral appearance, lower solar heat gain, fade protection, and naturally cleaner exterior glass.
• LoĒ³-366^® is commonly used for balanced energy performance and clear appearance.
• LoĒ²-272 is commonly reviewed for balanced Low-E performance, good visible light, and moderate solar control.
• LoĒ³-340+ is commonly used for direct sun and glare control.
• LoĒ-i89 combinations are commonly used for improved winter thermal performance, northern climates, and lower U-factor requirements.
• Triple pane LoĒ³-366^® with LoĒ-180™ is available when the project requires additional glass performance beyond standard dual pane configurations.
• Laminated glass is available with the same Cardinal LoĒ options.
• Specialty glass and blinds-between-glass options must be checked against size limits, glass package availability, lead time, and project performance requirements.
• The customer, dealer, contractor, architect, builder, or project team must confirm which glass package is required before ordering.

Grille Note: Grille type and grille style should be reviewed with the patio door configuration, glass selection, exterior color, interior finish, hardware finish, surrounding window package, and architectural appearance of the project before ordering.

Grilles Between the Glass

Internal grilles are positioned between the two panes of insulating glass. This provides the visual appearance of divided lites while keeping the interior and exterior glass surfaces easier to clean.

All internal grilles are available in two-tone finishes. The exterior color of the grille is matched to the patio door exterior color, and white is included on the interior side to coordinate with painted white interior finishes.

Common Use: Sliding patio door projects where a grille pattern is desired with easier glass cleaning and a cleaner surface compared with applied grilles.

Simulated Divided Lite Grilles

Simulated Divided Lite (SDL) grilles are mounted to the exterior surface of the glass on both the exterior and interior of the patio door. SDL grilles create a richer divided-light appearance compared with internal grilles alone.

Adding a third internal grille between the glass can further enhance the look of SDL grilles by creating additional visual depth through the insulating glass unit where that option is selected.

Common Use: Traditional, historic-style, architect-specified, or design-focused sliding patio door projects where a more authentic divided-lite appearance is desired.

Interior Removable Wood Grilles: Interior removable wood grilles may also be available for projects requiring that grille option. Ask a Casco sales representative for more information.

• Internal grilles are positioned between the panes of insulating glass.
• Internal grilles are available in two-tone finishes.
• SDL grilles are mounted to the exterior and interior glass surfaces.
• An internal grille between the glass can be added with SDL grilles for additional visual depth where available.
• Interior removable wood grilles may be available when that option is required.
• Grille type, grille pattern, exterior color, interior finish, hardware finish, glass selection, and patio door configuration should be reviewed together before ordering.
• Grille selection can help sliding patio doors coordinate with Casco Aluminum-Clad Windows, Aluminum-Clad Casement Windows, Aluminum-Clad Double-Hung Windows, and Casco Aluminum-Clad Swing Patio Doors.

Quick Summary: Casco Aluminum-Clad Sliding Patio Doors are sliding wood patio doors with heavy-duty extruded aluminum-clad exteriors, not roll-form aluminum or vinyl cladding, along with pine wood interiors, clear insulated glass with air fill as the base glass configuration, LoE glass options typically required when a project must meet specific local energy code requirements, available internal grilles and SDL grilles, screen fabric options, standard and keyed hardware options, narrow rail and French rail panel options, NFRC-certified performance, and multiple patio door configurations including single slide, double slide, bi-parting, telescoping, bi-parting telescoping, and stationary panel layouts. Blink blinds-between-glass options are available where size, product configuration, glass package, and project requirements allow. CLiC switchable privacy glass is not available on Casco Sliding Patio Doors.

An aluminum-clad sliding patio door is a wood patio door with aluminum cladding on the exterior and wood on the interior. The sliding panels move horizontally instead of swinging into or out of the room.

Casco Aluminum-Clad Sliding Patio Doors are commonly selected when a project needs large glass areas, exterior durability, interior wood appearance, space-saving operation, and access to a patio, deck, porch, yard, balcony, lake-facing area, or outdoor living space.

Casco Sliding Patio Doors operate by sliding one or more panels horizontally along the sill and track system. Depending on the selected configuration, the door may use a single active panel, multiple active panels, bi-parting operation, telescoping operation, or a combination of bi-parting and telescoping operation.

The selected door type affects panel movement, clear opening, screen planning, hardware review, handing, rough opening planning, and final installation details.

Sliding patio doors are commonly used for patios, decks, porches, balconies, lake homes, sunrooms, additions, remodels, new construction, walkout basements, covered outdoor areas, and spaces where a wide glass opening is desired without requiring door swing clearance.

They are especially useful where furniture placement, interior traffic flow, or exterior deck space makes a swinging patio door less practical.

The main advantage of a sliding patio door is that it provides a large glass opening while saving space. Since the panels slide instead of swinging, the door does not require interior or exterior swing clearance.

Sliding patio doors can also support larger glass areas and wide-opening configurations when the selected layout, panel sizes, glass package, hardware, and installation conditions allow.

General aluminum-clad window and patio door information can be reviewed in the Casco Window & Patio Door Guide. Sliding patio door sizing can be reviewed in the Casco Sliding Patio Door Size Chart. Color information can be reviewed in the Casco Color Chart.

Yes. Casco Aluminum-Clad Sliding Patio Doors are available with insulated glass and multiple LoE glass options. The base glass configuration is clear insulated glass with air fill. LoE glass options are typically required when a project must meet a specific local energy code requirement, U-factor requirement, SHGC requirement, or performance target.

Casco Aluminum-Clad Sliding Patio Doors are NFRC certified for performance documentation and project review.

Yes. Casco Aluminum-Clad Sliding Patio Doors are National Fenestration Rating Council (NFRC) certified. NFRC certification supports performance documentation for homeowners, contractors, dealers, architects, and project teams reviewing U-factor, solar heat gain, visible transmittance, and related performance data.

No. The base glass configuration for Casco aluminum-clad products is clear insulated glass with air fill. LoE glass options are typically required when a project must meet a specific local energy code requirement or performance target.

Before purchasing, the customer, dealer, contractor, architect, builder, or project team must review the applicable energy requirements and select the product configuration needed to meet those requirements. This may include selecting the correct LoE coating, including LoE²-272, LoE³-366^®, LoE³-340+, Quad LoE-452+, LoE-i89 combinations, gas fill, pane configuration, grille option, unit type, and overall door configuration.

Customers, dealers, contractors, architects, builders, and project teams are responsible for reviewing the project energy requirements before purchasing Casco aluminum-clad sliding patio doors. Requirements can vary by location, building code, project type, glass package, unit configuration, orientation, and overall project design.

Casco provides available product configurations, glass options, NFRC-certified performance information, and supporting product documentation. The project team must confirm that the selected door type, glass package, grille option, unit configuration, and overall product selection meet the applicable energy requirements before ordering.

Yes. Sliding patio doors save space because the panels slide horizontally instead of swinging inward or outward. This can be useful when furniture, walkways, decks, patios, railings, landscaping, or exterior grade conditions limit the space available for a swinging door.

A sliding patio door moves horizontally on a track. A swing patio door opens on hinges and requires swing clearance. Sliding patio doors are often selected when space-saving operation and larger glass areas are priorities. Swing patio doors are often selected when a hinged-door appearance or traditional French door operation is preferred.

For hinged patio door options, review Casco Aluminum-Clad Swing Patio Doors.

Yes. Custom sizes are available for Casco Aluminum-Clad Sliding Patio Doors. Sliding patio door size should be reviewed with the selected door type, panel layout, glass package, screen system, handing, rough opening, jamb depth, installation method, delivery access, and project requirements before ordering.

Casco Sliding Patio Doors are available in standard heights including 6'9", 6'11", and 8'0". Custom heights may be available up to 10' tall depending on the final configuration. Panels may be available up to 48" wide depending on the selected layout, glass package, hardware, and product review.

Larger active or stationary panels may be available by special review and custom quotation. Panels over 48" x 96" have limited warranty coverage and must be reviewed with Casco directly before ordering.

Casco Sliding Patio Doors are available in multiple configurations, including single slide, double slide, bi-parting, telescoping, bi-parting telescoping, and stationary or sidelite panel layouts where available.

Door type should be reviewed with the project opening, clear opening goals, furniture layout, walking path, screen needs, hardware requirements, delivery access, and installation conditions. For drawings and layout examples, review the Types section.

A single slide patio door uses one operating panel and one stationary panel. The active panel slides open to provide access, while the other panel remains fixed.

Single slide layouts are commonly used for standard patio, deck, and yard access openings.

A double slide patio door uses more than one operating panel. Depending on the selected layout, the active panels may provide more flexible operation than a standard single slide door.

Double slide layouts should be reviewed with screen planning, panel movement, clear opening, and hardware requirements before ordering.

A bi-parting sliding patio door uses operating panels that move away from the center, creating a centered opening and a balanced appearance.

Bi-parting layouts are commonly reviewed for larger patio, deck, lake-facing, and entertainment openings where centered access and ventilation are important.

A telescoping sliding patio door uses multiple panels that slide and stack, allowing a wider clear opening than a standard two-panel sliding door.

Telescoping layouts are often reviewed for remodels, additions, patios, decks, lake homes, and larger indoor/outdoor living spaces. Telescoping sliding patio doors require a deeper 7" jamb, so wall thickness and interior finish details should be reviewed early in the project.

A bi-parting telescoping sliding patio door combines center-opening operation with telescoping panel movement. Multiple moving panels create a wider clear opening from the center.

Casco’s Bi-Parting Telescoping Sliding Patio Door can be available up to 24' wide and can provide four moving panels with up to a 14' clear opening depending on the final configuration. Final availability depends on the selected layout, unit size, panel width, glass package, hardware, screen system, handling requirements, delivery access, structural opening, and installation conditions.

Because bi-parting telescoping doors are part of the telescoping door family, they also require a deeper 7" jamb and should be reviewed with the wall condition, interior finish plan, and installation method before ordering.

The standard Casco Sliding Patio Door panel uses a 2-1/2" narrow rail profile. This narrower profile helps maximize the glass area of each panel, creating more visible glass and a cleaner view.

The French Rail option uses a wider 4-1/2" rail profile. This upgrade adds more exterior color presence and more visible wood exposure on the interior.

French Rail is commonly used when a sliding patio door is installed near a Casco Aluminum-Clad Swing Patio Door or when the project team wants the sliding door to better mimic the larger rail appearance of a swing patio door.

Unequal panel sizing may be reviewed where available to better match the opening, traffic flow, or design intent. Unequal panel layouts should be confirmed with the selected door type, panel width, hardware, screen system, glass package, and product availability before ordering.

Larger active or stationary panels can be created in some cases, but they require custom quotation and should be requested directly through Casco’s office for review.

Casco Aluminum-Clad Sliding Patio Doors use a 4-9/16" jamb depth as a standard feature.

Telescoping sliding patio doors require a deeper 7" jamb. This applies to telescoping and bi-parting telescoping versions of the door.

Yes. Sliding patio door handing, active panel location, operation direction, and panel movement should be reviewed before ordering. Handing affects operation, screen planning, traffic flow, hardware review, installation, and customer expectations.

In sliding patio door layout drawings, X marks the active operating panel and O marks a passive, inactive, or stationary panel.

For bi-parting, telescoping, bi-parting telescoping, unequal panel, and other large-opening layouts, panel movement and active panel locations should be confirmed carefully before ordering.

The base glass configuration for Casco Aluminum-Clad Sliding Patio Doors is clear insulated glass with air fill. LoE glass options and upgraded glass packages are available when additional performance is required.

Because energy requirements vary by project location, building code, unit type, glass package, and configuration, the customer or project team must confirm whether the base glass configuration is acceptable or whether a LoE option is required before ordering.

Available glass options include LoE²-272, LoE³-340+, LoE³-366^®, LoE³-366^® with LoE-i89, Quad LoE-452+, Quad LoE-452+ with LoE-i89, triple pane LoE³-366^® with LoE-180™, LoE-i89, Neat^® naturally clean glass, tempered glass, laminated glass, obscure glass options, and Blink blinds-between-glass options where size, product configuration, and project requirements allow.

LoE options are typically required when a project must meet a specific local energy code requirement, U-factor requirement, SHGC requirement, or performance target. Glass selection must be reviewed with the patio door location, energy goals, applicable project energy requirements, solar exposure, privacy needs, grille selection, hardware finish, and project requirements before ordering. For more detail, review the Glass & Screen section.

The correct glass configuration depends on the project energy requirements, climate zone, sun exposure, room use, visible light goals, solar heat gain goals, and required NFRC performance. The base glass configuration is clear insulated glass with air fill. LoE glass options are typically needed when the project must meet a specific local energy code requirement or performance target.

Clear insulated glass with air fill is the base configuration. It may be appropriate only when the project does not require a specific Low-E performance package and the energy requirements allow it. Clear glass allows strong visible light, but it does not provide the same solar control, UV protection, or U-factor performance as the LoE glass packages.

LoE²-272 is commonly reviewed for balanced Low-E performance, good visible light, and moderate solar control.

LoE³-366^® is commonly used as a balanced high-performance Low-E option when the project needs improved energy performance, solar control, UV protection, and clear visibility.

LoE³-340+ is commonly used when greater glare control and lower solar heat gain are needed, especially for direct sun exposures.

Quad LoE-452+ is available when the project needs strong solar control with a clear, neutral appearance. It is commonly reviewed for hot, sunny exposures where reducing solar heat gain is a priority while maintaining useful visible light.

LoE-i89 is an interior surface coating used when additional U-factor improvement is needed. It is commonly reviewed when the project needs stronger interior-side heat retention or must meet stricter U-factor requirements.

The customer, dealer, contractor, architect, builder, or project team must confirm which glass package is required before ordering. Casco provides available glass options and product performance documentation, but the project team is responsible for selecting the product configuration that meets the applicable project energy requirements.

Yes. Obscure glass is available for sliding patio doors. It is commonly used where privacy is needed while still allowing light into the room, including side yards, close neighboring homes, bedrooms, private patios, and other areas where clear glass is not preferred.

Yes. Laminated glass is available for Casco aluminum-clad sliding patio doors. Laminated glass can be ordered with the same Cardinal LoE glass options when the project requires laminated glass along with a specific Low-E package.

Laminated glass is commonly reviewed when the project requires added safety, sound control, security considerations, impact resistance considerations, or project-specific glass requirements. The correct laminated glass configuration should be reviewed with the required Cardinal LoE coating, energy performance requirements, unit size, project location, and applicable code requirements before ordering.

No. CLiC switchable privacy glass is not available on Casco Sliding Patio Doors.

For sliding patio door privacy, review available obscure glass options or Blink blinds-between-glass where size, product configuration, glass package, and project requirements allow.

Yes. Blink blinds-between-glass options are available for Casco Sliding Patio Doors where size, product configuration, glass package, and project requirements allow. These options place the blind inside the insulated glass unit, helping protect the blind from dust, damage, and exposed cords.

Blinds-between-glass are useful when the customer wants integrated privacy and light control without a separate window treatment mounted over the patio door opening. Blinds-between-glass options must be reviewed for available sizes, glass type, Low-E requirements, operation type, warranty, lead time, and the project’s required energy performance before ordering.

Screen options should be reviewed with the selected sliding patio door type. Single slide, double slide, bi-parting, telescoping, and bi-parting telescoping patio doors may use different screen systems depending on the door layout, panel movement, opening width, and final configuration.

Standard screen, BetterVue, and PetScreen fabric options are available. BetterVue is used when improved visibility is desired. PetScreen is used when added screen durability is needed. Screen fabric selection should be reviewed based on visibility, airflow, durability, pets, high-traffic use, and customer expectations.

Casco Sliding Patio Doors are available with internal grilles, simulated divided lite (SDL) grilles, grille style patterns, and interior removable wood grilles where available. Internal grilles are positioned between the panes of insulating glass. SDL grilles are mounted to the exterior and interior glass surfaces.

No. Standard Casco Sliding Patio Door hardware does not include a keyed exterior.

Keyed exterior hardware is available as an option and should be reviewed before ordering when exterior access or keyed entry is required.

Keyed exterior hardware should be reviewed when the sliding patio door will be used as an entry point from a patio, deck, yard, balcony, or other exterior area where keyed access is desired.

Keyed hardware availability, finish selection, handing, panel layout, and final configuration should be confirmed during quoting.

Yes. Casco Aluminum-Clad Sliding Patio Doors can be used for replacement, remodel, addition, and new construction projects. Replacement requirements depend on the existing opening, rough opening condition, wall construction, interior trim, exterior cladding, installation method, sill condition, and final finish details.

For replacement projects, the existing wall thickness and interior finish condition should be reviewed before selecting the final sliding patio door configuration, especially when changing from a standard sliding patio door to a telescoping or bi-parting telescoping layout.

Yes, but telescoping sliding patio doors require additional review for retrofit and replacement applications. Telescoping and bi-parting telescoping sliding patio doors require a deeper 7" jamb. If the existing wall is narrower than the telescoping jamb depth, the project may require an interior build-out, trim return, jamb extension planning, or other finish work to properly address the deeper frame within the existing wall condition.

This wall thickness and interior build-out review should be addressed before ordering so the project team can plan the rough opening, finished wall depth, interior trim, flooring, sill condition, casing, and final appearance around the door.

Yes. Casco Sliding Patio Doors can be used for new construction and addition projects. Door type, rough opening size, structural support, sill condition, exterior cladding, interior finish, jamb depth, flashing details, and installation method should be reviewed before ordering.

Shared Product Note: The sections below cover aluminum-clad product details that repeat across Casco’s aluminum-clad product line, including extruded aluminum cladding, wood interiors, finish options, Cardinal glass packages, energy-code review, screens, laminated glass, obscure glass, and blinds-between-glass options. CLiC switchable privacy glass is not available on Casco Sliding Patio Doors.

An aluminum-clad wood patio door uses aluminum on the exterior and wood on the interior. Casco aluminum-clad products use heavy-duty extruded aluminum cladding on the exterior, not roll-form aluminum or vinyl cladding. The extruded aluminum-clad exterior helps protect the outside of the patio door from weather exposure, while the wood interior provides a traditional appearance and finish flexibility inside the home.

This aluminum-clad section applies broadly across Casco aluminum-clad window and patio door product lines.

Aluminum-clad patio doors are selected when a project needs exterior durability and interior wood appearance. The aluminum exterior reduces exterior maintenance compared with exposed wood, while the pine interior provides a warmer interior appearance that can coordinate with trim, cabinetry, flooring, doors, and other interior finishes.

Yes. Casco aluminum-clad windows and doors use extruded aluminum cladding. Casco does not use roll-form aluminum cladding or vinyl cladding on its aluminum-clad product line.

Extruded aluminum is a heavier-duty exterior cladding system that is formed through an extrusion die, creating a stronger and more substantial profile than thin roll-form cladding or vinyl exterior cladding.

Extruded aluminum cladding is made from a solid aluminum profile shaped through an extrusion process. This creates a rigid, substantial exterior component with more strength, better profile definition, and a heavier-duty feel.

Roll-form aluminum cladding is typically made from thinner aluminum sheet material that is bent or formed around the exterior of the window or door. Roll-form cladding can provide an aluminum exterior surface, but it is generally a lighter-duty cladding approach compared with extruded aluminum.

For customers comparing similarly priced aluminum-clad products, the cladding method matters. A patio door with extruded aluminum cladding is not the same construction level as a product using thin roll-form cladding.

Extruded aluminum cladding provides a durable metal exterior over the wood patio door. It is used when the project requires a more substantial exterior cladding system with a clean finish, strong profile shape, and long-term exterior durability.

Vinyl cladding uses a vinyl exterior surface instead of aluminum. Vinyl cladding can reduce exterior maintenance compared with exposed wood, but it does not provide the same heavy-duty aluminum exterior construction as extruded aluminum cladding.

Casco aluminum-clad sliding patio doors are built for customers who want the strength and appearance of aluminum on the exterior with the warmth and finish flexibility of wood on the interior.

Casco aluminum-clad products are available with exterior standard colors, exterior Estate Colors, and custom exterior color options. Physical color samples must be reviewed before final selection whenever color accuracy is important.

For current color galleries, review the Colors section.

Factory stain, prime, or paint finishes are available, including custom interior paint. Interior prefinished wood colors are also available for projects requiring a factory-finished pine interior.

U-factor measures heat flow through the window or door assembly. A lower U-factor means better resistance to heat loss. This is often important in cold climates and energy-code-driven projects.

Solar Heat Gain Coefficient (SHGC) measures how much solar radiation enters as heat. A lower SHGC helps reduce solar heat gain and is often important in hot, sunny climates or high-sun exposures.

Visible Transmittance (VT) measures how much visible light passes through the glass. A higher visible transmittance means more daylight and a clearer view.

UV transmission relates to fading protection. Lower UV transmission helps reduce fading potential for furniture, flooring, fabrics, artwork, and interior finishes.

Laminated glass uses an interlayer between glass layers and is commonly reviewed for added safety, sound control, security considerations, impact resistance considerations, or project-specific glass requirements.

Privacy control can be handled through obscure glass or Blink blinds-between-glass on Casco Sliding Patio Doors depending on whether the project needs permanent privacy or integrated blind operation.

Glare control reduces the intensity of visible light in direct sun conditions. This is useful for high-sun exposures, rooms with screens or televisions, commercial spaces, and areas where harsh daylight is a concern.

For a base non-code-driven configuration: clear insulated glass with air fill may be used when the project does not require a specific Low-E package and the applicable energy requirements allow it.

For balanced Low-E performance and good visible light: LoE²-272 is commonly reviewed when the project needs moderate solar control and Low-E performance.

For balanced energy performance and clear appearance: LoE³-366^® is commonly selected when the project needs a strong all-around Low-E option.

For direct sun and glare control: LoE³-340+ is commonly selected where glare and solar heat gain are the main concerns.

For strong solar control with a clearer neutral appearance than heavy glare-control glass: Quad LoE-452+ is commonly selected for hot, sunny exposures where reducing solar heat gain is a priority while still maintaining useful visible light.

For improved winter thermal performance, northern climates, and lower U-factor requirements: LoE-i89 combinations are commonly selected when the project needs stronger interior-side heat retention or must meet stricter U-factor requirements.

For laminated glass requirements: laminated glass is available with the same Cardinal LoE glass options when the project needs laminated glass for safety, sound control, security considerations, impact resistance considerations, or project-specific requirements.

For permanent privacy: obscure glass is available where the project needs privacy while still allowing light into the room.

For integrated light and privacy control: Blink blinds-between-glass options are available where the project requires cordless blinds enclosed inside the insulated glass unit. These options help control privacy and light while keeping the blind protected between panes of glass.

For projects with specific local energy requirements: the glass package must be selected based on the required U-factor, SHGC, VT, climate zone, code path, unit configuration, and supporting NFRC performance information before ordering. Specialty glass and blinds-between-glass options must also be checked against size limits, available glass packages, and project performance requirements before ordering.

Before purchasing Casco aluminum-clad sliding patio doors, customers and project teams must confirm the applicable project energy requirements and select the product configuration needed to meet those requirements. The base glass configuration is clear insulated glass with air fill; LoE options such as LoE²-272, LoE³-366^®, LoE³-340+, Quad LoE-452+, and LoE-i89 combinations are typically required for projects that must meet specific local energy code requirements. This includes reviewing the door type, glass package, grille option, unit configuration, project location, building code requirements, and supporting NFRC performance information.

For telescoping and bi-parting telescoping sliding patio doors, project teams should also review the 7" jamb depth, wall thickness, interior build-out requirements, rough opening preparation, and finished interior trim details before ordering, especially in retrofit or replacement applications where the existing wall may be narrower than the telescoping door frame.
