Flat Roof Insulation Products

XPS insulation is an excellent choice for flat roofs due to its closed-cell, moisture-resistant rigid foam board design. Offering a range of R-values and thicknesses, it delivers versatile thermal performance. Certain variants are engineered for high load-bearing capabilities, making them suitable for commercial flat roof insulation where rooftop installations and occasional maintenance foot traffic are involved.

XPS insulation is also effective in tapered insulation systems, providing flexibility for various flat roof designs. For protected roof membrane assemblies (PRMA), XPS insulation can be placed directly over the membrane or under pavers, maintaining its moisture resistance and robust structure for long-term performance. This high-performance flat roof insulation balances thermal efficiency, durability, and ease of installation, reducing energy consumption and enhancing the overall performance of the building roof insulation.

Cellular glass insulation is a high-performance option for flat roofs, offering unique properties. This closed-cell, rigid foam board is impermeable to water and vapor, providing essential moisture resistance. Its non-combustible nature includes excellent fire safety, making it a great choice for commercial flat roof applications. This insulation, made of completely sealed glass cells, is ​resistant to chemicals and pests, making it a durable and reliable insulating choice. Overall, cellular glass insulation provides dependable performance with excellent moisture and fire resistance, meeting diverse customer needs for building roof projects.
