Class A Thermal Underlayment
SOL-R-SKIN Class A Thermal Underlayment starts with a 99% highly polished, scrim-reinforced aluminum layer, bonded to fiberglass, then laminated to a synthetic underlayment substrate.
The result is a robust radiant barrier underlayment that pairs thermal performance with a high level of fire resistance.
- Tested thermal performance of approximately R-5.5 (ASTM C1363/C1224).
- Class A / Class 1 fire rating as tested to ASTM E108 and ASTM E84.
- Helps meet evolving energy and fire codes when used as part of a complete roofing system.
- Approved for use under shingles, tiles, metal roofing, and stone coated metal roofing systems.
Compared to older reflective insulations built around bubble or foam cores, SOL-R-SKIN Class A Thermal Underlayment is designed to fit more applications, especially where fire performance and code compliance are a priority.
