Roof Insulation: EPS Foam Moisture Sealant Membrane

EPS Foam Roofing Systems from Northwest Foam Products, Inc.

Contractors and architects are increasingly finding that roofing systems using Expanded Polystyrene (EPS) foam from Northwest Foam Products, Inc. can meet the needs of the most demanding building requirements. EPS foam offers measurable energy savings, long-term R-value, effective moisture sealant water resistance, and dimensional stability and strength when properly installed and protected from moisture. These systems may include flat and/or tapered foam insulation for use in traditional built-up assemblies and most single-ply membrane systems.

Moisture is extremely detrimental to any roofing system. The purpose of the membrane is to keep the water out. Results for R-value performance indicated no deterioration in R-value over time, meaning EPS thermal resistance values may be used without adjustments for aging.

EPS foam roof insulations are compatible with most commercial roofing systems, including but not limited to built-up roofing, modified bitumen systems, and single-ply membrane systems that are either ballasted, mechanically fastened, or fully adhered. Expanded polystyrene insulation meets the requirements of ASTM C 578 Standard Specification for Rigid, Cellular Polystyrene Thermal Insulation.
