WebJohns Manville Polyiso foam sheathing insulation boards provide a continuous layer of insulation to reduce thermal bridging and improve energy efficiency. Polyiso consists of a uniform closed-cell polyisocyanurate foam core and provides one of the highest R-values per inch of any rigid insulation. Filter Products By Jump To Foam Board, Sheathing WebHalf-inch thick rigid foam insulation has an R-value of R-2 to R-3.5. Foam thicker than a half-inch will yield even higher R-values. Adding ½ inch of rigid foam insulation (R-2 in this example) will increase a 2x6 stud wall from an effective R-15 to an effective R-17. This is an increase of 13% of effective thermal resistance.

WebOffering insulation products across a broad temperature spectrum to fit your needs. WebWhile closed-cell foam has a greater R-value and provides stronger resistance against moisture and air leakage, the material is also much denser and is more expensive. Open-cell foam is lighter and less expensive but should not be used below ground level where it could absorb water.
