Cornell ThermaCal Nail Base Roof Insulation Panels

These nail base roof insulation panels provide a pre-attached substrate that can adhere to multiple overlying roof covering types, including asphalt shingles, tile, metal, or slate.

Ventilated versions help expel excess moisture before it condenses in the deck or roofing system and causes damage. Ideal for structures with steep-slope roofs or cathedral ceilings, such as churches, institutions, and schools.
