Dear Gerb: As the product description notes, this DOW polyiso foam board delivers R-6. That sai new research found that polyiso R-value drops along with the temperature.


It is designed for use in walls and attics of new and retrofit applications. What is the are value of rigid insulation? How to install rigid foam sheathing? Install it anywhere from the roof to the foundation. You can even place it under the foundation slab.

This is the product that I typically use to insulate basement walls. Styrofoam brand name. Dow’s proprietary extrusion process enables precise control of parameters such as density, cell size and cell orientation. This yields foam boards that can stand up to the most demanding composite panel applications.


Buy or rent a table saw if you need the rigid foam insulation to fit exact measurements. It is available in several thicknesses and R-values. It can be installed on the exterior of the foundation walls, but in order to be effective, needs to be installed to the full height of the wall which means protecting the above grade portion.


Polyiso would be one of the best-performing insulation rigid foam boards on the market today giving the highest R-values for the least thickness. Polyiso insulation can be used in so many different locations and effectively can totally replace glass wool and mineral wool in almost every application.

Rigid foam is routinely used to insulate the interior or exterior of foundation walls. On above-grade walls, exterior foam improves the performance of a wall or insulated roof by reducing thermal bridging, improving air-tightness, and raising the R-value of the entire assembly.


WARNING: Rigid foam insulation does not constitute a working walkable surface or qualify as a fall protection product. XPS) Rigid Foam Insulation is a closed cell, moisture-resistant rigid foam board well suited to meet the needs for a wide variety of building applications.
