Crafted with precision using extruded polystyrene (XPS), this insulation board sets new standards for energy efficiency, durability, and environmental responsibility. With thickness ranging from 50mm to 245mm, Polyfoam Roofboard Extra ensures optimal thermal insulation for a wide range of applications, including green roofs, flat roofs, and paving slabs. Its high compressive strength of 300 kPa guarantees superior support, making it perfect for heavy-duty constructions. In today's climate-conscious world, Polyfoam Roofboard Extra is the eco-warrior's choice. Boasting a low Global Warming Potential (GWP) and zero Ozone Depletion Potential (ODP), it actively contributes to reducing the harmful effects of greenhouse gases. Additionally, it holds the esteemed BBA certification, cementing its credibility as a top-quality construction product. Designed to resist water absorption, Polyfoam Roofboard Extra remains highly resistant to water, ensuring long-lasting thermal performance. When used along with the slimline zero membranes, its compatibility allows for a seamless integration with various roofing systems, preventing moisture ingress and safeguarding the structural integrity of your roof. What sets Polyfoam Roofboard Extra apart is its ability to provide exceptional thermal insulation. Its remarkable thermal conductivity properties ensure a comfortable living environment by minimising heat loss or gain, ultimately reducing energy consumption and costs. Additionally, it resists repeated freeze/thaw cycles of the surroundings, giving consistent energy savings The versatility of Polyfoam Roofboard Extra extends beyond insulation. Its exceptional strength makes it suitable for use under ballast, paving slabs, or even green roofs. The highly resistant composition guarantees the durability of your roof, protecting it from the harshest weather conditions. But the benefits don't end there. Polyfoam Roofboard Extra has achieved the coveted BES 6001 certification, demonstrating its commitment to sustainability. With its environmental product declaration, you can be confident that you are making a responsible choice for your project.
