Meets the requirements of ASTM C 1289, Type II, Class 4, Grade 1
High-Density Polyisocyanurate Foam Core: Closed cell polyisocyanurate foam technology provides additional insulation value (R-value of 2.5), with lightweight and low water absorption characteristics.
Inorganic Coated Glass Facers: (With no cellulose) Provide improved resistance to mold growth, as well as a smooth surface that performs well with self-adhering systems, and efficient adhesive application in adhered single ply systems.
Lightweight: Offers labor and installation efficiencies and allows more options
for situations where the overall weight is a concern. This also means easy
hoisting, staging and maneuvering around the roof.
User Friendly: ProtectoR HD allows easy & efficient scoring, cutting and snapping which permits fast, tight fabrication and all in a low dust environment.
High R-Value (2.5 R): Provides significantly more thermal insulation (R-value) than wood fiber or gypsum boards.
Resistance To Damage: High impact, flexural and compressive strength provides a protective layer for insulation while working with the membrane above to ensure maximum performance and longevity.
Up to 50% Fewer Fasteners: Achieves FM 1-90 utilizing 8 fasteners per 4'x 8' board with an adhered reinforced membrane and 11 fasteners per 4'x 8' board with an adhered non-reinforced membrane over a min. 22 ga steel deck or structural concrete deck. Refer to fastening patterns on page 2.
Fire Resistance: Achieves UL Class A approval directly over a combustible wood deck up to 1/2:12" slope.
Cell phones, text messages, notes being passed, and side-bar conversations are disruptions that cannot be controlled in a classroom environment. Protection from outside elements and acceptable sound transmission is something that can be controlled by having a correctly designed and properly installed roofing system.
Against the backdrop of the Rocky Mountains’ Front Range, commercial real estate developer Trammell Crow Company (TCC) transformed 70 acres of farmland into an industrial park. All new infrastructure—roads, electricity, water, sewage—was put into place before a massive 818,300 square foot roofing project was constructed.
