When a home has low attic insulation or air leaks, it causes the HVAC system to work harder. Foam Expert Group leads to higher energy bills and discomfort in the home. By adding attic insulation, you can reduce your energy usage by up to 40 percent.
It’s important to understand the different types of attic insulation available before you make a decision. The type you choose will depend on several factors, including the local climate and your budget.
Fiberglass batt insulation is the most common type of attic insulation. It consists of small fiberglass strands, which help to keep warm air inside in the winter and cool air outside in the summer. It’s also a fire-retardant, which makes it safer than other kinds of insulation. However, fiberglass doesn’t mix well with moisture. It will sag and lose its insulative value if it gets wet, so it’s important to properly seal air leaks before installing fiberglass batt insulation.
Why Attic Insulation Is Crucial for Energy Efficiency
Blown-in cellulose insulation is another attic insulation option. It’s made of recycled paper products and is blown in using a special blowing machine. The material is flame-proofed with boric acid before it’s blown into the attic. It’s more expensive than fiberglass, but it’s more effective at sealing gaps and cracks.
Foam spray insulation is an attic insulation alternative to fiberglass and cellulose. It’s sprayed in and expands to fill in gaps and cracks. It’s a good choice for tight attics, since it fills in difficult-to-reach areas of the attic and can be used on its own or with other types of insulation.
