When properly installed, roof insulation prevents heat loss from a building. This is important because it reduces energy bills and increases the comfort level in a home or commercial building. Additionally, it keeps pollutants, harmful toxins, and allergens out of the interior, improving air quality.
There are many different types of insulation materials, including fiberglass and cellulose. Each type of material has a different R-value which indicates how effective it is at insulating. The R-value of each material is calculated by dividing the thickness by the thermal conductivity. In general, the higher the R-value is, the more insulating it will be.
If you’re looking to upgrade your attic insulation, there are two options: loose-fill or spray foam. Blown-in and spray foam insulation must be installed by a licensed professional as they require the use of powerful tools and personal protective equipment. This helps to ensure that the professionals don’t inhale or swallow any potentially hazardous particles.
Loose-fill insulation comes in bags of loose fibers which can be blown into tight spaces in walls or ceilings. It’s also great for filling in areas that are difficult to reach, such as the gaps between joists or wall studs. This type of insulation is a little more costly than other types, but it can provide exceptional insulating power and help to significantly lower energy costs over time.
Foam board insulation is both a radiant and air barrier which works to keep the attic space warm and dry while preventing moisture accumulation. It prevents condensation that would otherwise lead to mold or mildew and is fire resistant, which protects the integrity of the attic structure.
