Drew Foam manufactures three types of roofing insulation: conventional or flat panel, tapered, and composite or structural board roof insulation. EPS offers great design versatility to meet a wide range of job conditions, is easy to handle, ad puts a minimal amount of weight on the roof. EPS manufactured by Drew Foam is equally suited to new construction or reproofing applications. EPS roofing insulation provides excellent R-values and low water absorption at a low coast in both asphalted built up roofs and single ply membrane systems.

Conventional or Flat Panel roofing provides a low-cost means to meet today’s stringent energy requirements. Available in a variety of thicknesses, flat panel EPS provides maximum dimensional stability and high thermal efficiency. It is ideal for use in a single-ply membrane systems and economically adds R-value in built up roof systems.

Drew Foam can help you custom design pre-tapered EPS insulation for any roof layout. With tapered EPS you can reduce framing costs, achieve positive drainage and have superior thermal insulation with one product and with a single step.

Composite or structural board is laminated at Drew Foam or on the job site to add strength and durability to your EPS insulation. The top surface can be laminated as a protective layer for traffic and hot asphalt, single-ply adhesives, and modified bitumen applications. The bottom surface can be laminated to act as a thermal barrier and flute spanning layer. Laminate can be applied to both surfaces on either flat or tapered board.
