since local building code requirements for insulation R-values differ between attics and walls. Attics (R-30 to R-60) often need greater thermal resistance than walls (R-13 to R-23), and code ...

Generally, the higher the R-value, the more effective the insulation ... Step 5: Apply vapor barrier over batting for exterior walls. If the insulation will be installed in the exterior walls ...

The result is the following guide to the best insulation for exterior walls. R-value 13.1 Sika’s Rmax Pro Select board is essentially dense foam insulation for walls in sheet form.

Typical R-value: R-3.8 and R-6.8 per inch of thickness, depending on the type. Where commonly used: Basement and crawl space walls, and as continuous insulation on a house’s exterior.

Do you prefer warm or cool weather? Or are you more like Goldilocks, and like your weather ‘just right’? When it gets too hot or too cold outside, it’s time to find someplace more comfortable. Our ...
