The R-value that’s advertised on insulation products refers to their thermal resistance. Thus, products with higher R-values have the most resistance to heat flow and are the most effective at insulating spaces. R30 insulation products offer enough thermal resistance to be used in attics for homes classified by the US Department of Energy to be under climate Zones 1 to 3. They can also be used on floors and crawl spaces for homes within climatic Zones 4 through 7. Don’t risk the health and comfort of your home’s occupants by leaving it under-insulated. Get your indoor temperature under control by installing proper insulation. At Pacific Insulation Supply, we’ll be happy to help you choose the right solutions from a range of R30 products.
