Keep your home’s temperature balanced with R15 insulation materials. Thanks to the products’ low permeability, cold and hot air can easily be filtered out of your residence. That makes the temperature either in cooler in the summer or warmer in the winter. Moreover, insulation materials with this R-value are versatile and easy to cut, making them suitable to use in different parts of a property. According to the US Department of Energy, they are best used on 2×4 walls in homes within climatic Zones of 1 to 7. They can also be used for crawl spaces in homes within Zone 2. Whether you need insulation material in your exterior walls, ducts, or foundation, R15 insulation can work in those areas.
