Rigid Foam And Batt Insulation

Foam board insulation can add insulation and eliminate thermal bridging when used in wall and ceiling assemblies insulated with batts.

Rigid foam and batt insulation.

Polystyrene and polyurethane are the most common materials used in making foam board. There are a few different kinds of foam board insulation diyers should know about. Flash and batt insulation is one example of a new technique being implemented by insulation contractors. These are panels of rigid foam sold in 4 by 8 foot sheets in a variety of thicknesses from 1 4 to 2 inches it is also sold in large bundled panels joined at the ends accordion style for use as an exterior sheathing material.

It can potentially replace the vapor barrier and house wrap as well. Nor will that approach address thermal bridging through the studs. It is often used as a layer of continuous insulation on exterior walls and in the roof. Rigid foam insulation packs a lot of r value into a relatively thin package.
