Webbclaimed R-values as high as R-14 for an 8-inch CMU wall, although those ratings were based on a very light-weight 60-pcf block. Tests conducted by the Northwest Concrete Masonry Association, however, found an R-value of 11 for a wall built with a more typical 100-pcf block.

Webb30 okt. 2013 · In reality, the R-value of an 8-inch CMU wall insulated with amino foam is highly dependent of the density of the concrete. With very low-density blocks—85 pounds per cubic foot (pcf)—two-core, blocks insulated with this insulation provide a whole-wall R-value of 11.3. With heavier (more dense) concrete blocks the R-values drop.
WebbInjection Foam Insulation's Higher R-Value With an R-Value of 4.0 to 5.1 per inch, depending on the manufacturer, pre-expanded injection foam provides a higher R-value than fiberglass or cellulose, and it seals the building from air leakage at the same time.

WebbSpray foam (expanding foam in the UK) is a chemical product created by two materials, isocyanate and polyol resin, which react when mixed with each other and expand up to 30-60 times its liquid volume after it is sprayed in place. This expansion makes it useful as a specialty packing material which forms to the shape of the product being packaged and … WebbLoose-fill cellulose has an R-Value of R-3.1 to R-3.8 per inch. R-Value measures an insulation’s thermal resistance. Thermal resistance is the material’s ability to resist that heat transfer through conduction. But in the case of injection foam insulation, R-Value doesn’t tell the whole story. RetroFoam Insulation R-Value
