Rigid Foam Roof Insulation

Install roofing underlayment flashing and cladding as per best practices.

Rigid foam roof insulation.

Rigid insulation is one of the best tools to reduce your energy costs. You can even place it under the foundation slab. Nailbase must be vented in high snow load areas. Rigid foam installation after the roof deck is ready the rigid foam insulation is installed.

Once the roof demo was complete and the flat roof was cleared of any remaining debris some rotted 2x material around the perimeter of the roof was replaced. 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. Install it anywhere from the roof to the foundation. They keep your home at a comfortable temperature without the need to crank your heat.

Rigid insulation layers exterior to existing roof sheathing must provide sufficient thermal insulation r value to control condensation risk see climate specific guidance. Depending on the type of insulation you choose and the desired r value you want for your facility you may need to build up a few layers of insulation. Polyiso is an easy cost effective sustainable and energy efficient construction material. But one thing that some builders don t like is the high global warming potential of some blowing agents used to make the foam.

A continuous layer of rigid foam insulation in wall and roof assemblies leads to lower energy consumption an environmental plus to be sure. Expanded polystyrene eps extruded polystyrene xps and polyisocyanurate are the most used types of rigid foam insulation. 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. Install nailbase for cladding.

Rigid foam insulation also known as insulating boards provide high r values. The r value is a measurement of the heat loss and heat gain. The rigid foam board insulation we used was 2 thick and came in 4 x 8 sheets.
