Rigid Foam Roof Insulation

All atlas acfoam polyiso insulation boards are qualitymark certified providing consumers an easy way to identify premium products that meet or exceed building codes for the best in roof performance.

Rigid foam roof insulation.

Install nailbase for cladding. Polyiso is an easy cost effective sustainable and energy efficient construction material. Rigid foam insulation also known as insulating boards provide high r values. Nailbase must be vented in high snow load areas.

Rigid insulation layers exterior to existing roof sheathing must provide sufficient thermal insulation r value to control condensation risk see climate specific guidance. The rigid foam board insulation we used was 2 thick and came in 4 x 8 sheets. Expanded polystyrene eps extruded polystyrene xps and polyisocyanurate are the most used types of rigid foam insulation. Rigid insulation is one of the best tools to reduce your energy costs.

Rigid foam installation after the roof deck is ready the rigid foam insulation is installed. They keep your home at a comfortable temperature without the need to crank your heat.

A continuous layer of rigid foam insulation in wall and roof assemblies leads to lower energy consumption an environmental plus to be sure. Install it anywhere from the roof to the foundation. R panel is manufactured with a closed cell polyisocyanurate foam core bonded to fiberglass reinforced facers and designed for use over metal nailable and non nailable roof decks with a variety of membrane systems.
