Rigid Board Insulation

Rigid foam-board insulation is typically installed as an insulation and vapour barrier over exposed concrete or on the outside of exterior walls. It generally offers an R-Value of “5 per inch”, based on the thickess of the material (ie: a 2″ thick sheet would have an R-Value of 10). We commonly install thicknesses of 1″, 1.5″, and 2″. Sheets are nailed or glued to your exterior wall, and all joints are sealed with construction tape to further reduce air flow.
