  • Screen


    Standard Screen

    As the standard in the industry for years, this vinyl coated fiberglass screen material is sure to keep insects out.



    BetterVue insect screen is an improved visibility screen that offers clearer views (20%) with enhanced insect screen performance (10%). Additionally, BetterVue includes Microban antimicrobial product protection to stay clean longer and Water Shed TechnologyTM.



    PetScreen is tear and puncture-resistant to prevent damage by dogs and cats and is ideal for use in high-traffic areas. Additionally, PetScreen includes Microban antimicrobial product protection to stay clean longer and Water Shed TechnologyTM.


    Energy Efficient Coated Glass



    LoE-x89® is a neutral color exterior glass surface coating (indium tin oxide) which reduces outdoor glass condensation. LoE-x89® is designed to be used on surface #1 to reduce heat loss and the occurrence of the glass falling below the dew point. This reduces the opportunity for exterior condensation to occur. In addition, LoE-x89® has a titanium dioxide coating which keeps the exterior glass surface cleaner for a longer period.

    Safety Glass

    • Tempered safety glass and Plexiglass are available in lieu of standard annealed glass.

    Obscure Glass

    Oftentimes used in bathrooms, mud rooms, and utility areas, specialty glass provides different levels of privacy while still allowing light into a room.
