Types of Attic Insulation
Quality Insulation helps make it easier to maintain a comfortable home temperature, whether it’s hot in the summer or cold in the winter. This saves you money on energy bills by reducing the demand for fossil fuel-based heating and cooling systems. It also prolongs the life of your HVAC appliances.
The most common type of attic insulation is fiberglass batts or blankets, which are commonly available at home improvement stores. However, it’s important to note that these products should be “unfaced,” meaning that they have no paper or foil backing, as this material can promote moisture buildup in your attic.
How to Choose the Right Attic Insulation for Your Home
Blown-in (loose fill) insulation is another option that uses a blowing machine to blow loose particles of fiberglass, mineral wool or cellulose into your attic space, ensuring complete coverage and eliminating any gaps and air leaks. This type of insulation is also environmentally friendly, as it’s made from recycled materials. It is a standard choice for new homes, as it offers better R-value than fiberglass batts and can be installed quickly and efficiently. However, it can settle over time and may lose its R-value. It can also absorb moisture, which promotes the growth of mold and mildew.
Spray foam insulation requires a professional installer to ensure that the materials are properly applied to the attic’s structural surfaces and sealed against air leaks. This option is more expensive than the other types of insulation, but it offers better heat resistance and moisture resistance. It can also seal attic spaces that are difficult to reach or have irregular layouts, preventing air from entering or leaving your home.
