Insulating Glass Units (IGUs) for Glazing Contractors

Cardinal IG - Simply the Best Glass. Built to Order. Delivered Fast.

Casco is a trusted regional distributor of Cardinal IG insulating glass units (IGUs), supplying glazing contractors, glass shops, and window professionals across Chicago, the Midwest, and the Eastern U.S.—with lead times and delivery reliability that keep jobs on schedule.

All units include Preserve® protective film, a factory-applied, low-tack surface barrier that protects the glass during fabrication, transport, and jobsite handling—minimizing cleanup time and reducing the risk of damage during installation.

IGUs are constructed using XL Edge® or Endur® warm-edge stainless steel spacers, CNC-bent and laser-welded to eliminate seams around the perimeter. This advanced construction method reduces failure points common in kinked or butt-jointed spacer bars. Both spacer systems improve thermal performance, increase condensation resistance, and are backed by a 20-year seal failure warranty. XL Edge units have a proven failure rate below 0.2%, among the lowest in the industry.

IGU Glass Options:

  • Dual-pane and triple-pane insulated glass with Low-E coatings and argon gas
  • Tempered, laminated, obscure, and mono-pane glass options
  • Specialty shapes and custom sizes—CAD-supported with minimal template requirements
  • Painted stainless spacer finishes available for refined sightlines
  • Optional upgrades: Neat+™ self-cleaning glass and CLiC™ switchable privacy glass
Designed for Professional Use:
  • Jobsite-friendly, reusable packaging reduces waste and cleanup
  • Weekly delivery routes serve the Midwest and Eastern United States
  • Short lead times with consistent turnaround on custom IG orders
  • Automated QA systems ensure consistent quality and accuracy at scale
Common Applications:
  • Residential window seal failure glass replacement
  • Light remodeling and reglazing projects
  • Insurance claim glass replacements and breakage repairs
  • Custom insulated units for service-driven glass shops and window specialists

Cardinal residential insulating glass units from Casco deliver industry-leading quality, performance, and field efficiency—ideal for window replacements, reglazing, and repair work in single-family homes, multi-unit properties, and light residential construction.
