What is the R-value for rigid insulation?

What is the R-value for rigid insulation?

Extruded polystyrene: Extruded polystyrene (XPS) rigid foam is usually blue or pink in color, with a smooth plastic surface. XPS panels typically aren’t faced with other material. The R-value is about R-5.

What R-value is foam board?

Foam board insulation R-value varies based on type but is anywhere from 3.6 per inch of insulation thickness to 8.0. The types of foam board insulation include polyurethane, polyisocyanurate, extruded polystyrene foam, and expanded polystyrene foam.

Which rigid foam insulation is best?

Expanded polystyrene (EPS), or beadboard, serves as the best insulating rigid foam for homeowners on a budget. This material costs less than other rigid foam boards, but still offers an R–value of 3.6 to 4.2 per inch, according to Fine Homebuilding.

What sizes of rigid insulation board are available?

Rigid insulation board is available in quantities ranging from individual foam sheathing to bundles to units. Here, you can find overstock, discontinued, non-standard sizes, and more.

Is rigid foam insulation right for your project?

Choose rigid insulation wisely, and consider the effect its characteristics will have on the performance of the your project, overall product cost, and the best way to get the bang for your buck.

What type of rigid insulation has the highest are value?

Polyisocyanurate: Known as polyiso for short, polyisocyanurate foam has the highest R-value per inch (R-6.5 to R-6.8) of any rigid insulation. Simply so, how thick is r13 rigid insulation? Standard fiberglass insulation batts or blankets provide an R-value of 2.2 to 3.8 per inch of thickness.
