When determining how much insulation you need don t guesstimate calculate.
The higher the r value the greater the insulation performance.
Steep slope or pitched roofs will almost never include insulation as a part of the roof assembly.
Used most widely in insulated concrete forms and structural insulated panels.
Traditional loose fill insulation such as fiberglass or cellulose has an r value between r 2 0 and 3 5 per inch of thickness.
Polyiso is an easy cost effective sustainable and energy efficient construction material.
When new energy codes are adopted the required r value is often increased.
You can even place it under the foundation slab.
Install it anywhere from the roof to the foundation.
The r value is a measurement of the heat loss and heat gain.
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.
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.
