Rigid foam roof insulation.

Rigid foam insulation also known as insulating boards provide high r values. There s a reason polyiso rigid foam insulation is used in more than 70 of commercial roof construction as well as in many residential builds. But one thing that some builders don t like is the high global warming potential of some blowing agents used to make the foam. The r value is a measurement of the heat loss and heat gain.

Rigid foam installation after the roof deck is ready the rigid foam insulation is installed.

Expanded polystyrene eps extruded polystyrene xps and polyisocyanurate are the most used types of rigid foam insulation. Install roofing underlayment flashing and cladding as per best practices. A continuous layer of rigid foam insulation in wall and roof assemblies leads to lower energy consumption an environmental plus to be sure. Johns manville r panel rigid roof insulation board offers r values of up to r 23 6 providing high thermal efficiency.
