Roofs account for 35% of building heat loss. Our 2 rigid insulation panels feature interlocking tongue-groove designs that eliminate gaps, achieving U-values as low as 0.18 W/m²K. The 50mm foam insulation sheets integrate seamlessly with aluminum composite panels (ACP) for ventilated façade systems, reducing surface temperatures by 15-22°C in desert climates. Contractors value the 1.2m x 2.4m insulation panel board dimensions for fast installation - a 10,000 sq.ft roof can be insulated in 3 days versus 8 days with fiberglass. With 25-year warranties on moisture-resistant rigid foam board insulation, we help clients from Canada to Saudi Arabia combat ice dams and urban heat islands.
