Attic insulation is one of the best investments you can make to reduce your energy costs, improve comfort and enhance indoor air quality. It creates a barrier that prevents warm air from escaping your home during the winter and cool air from seeping in during summer, helping to keep a steady indoor temperature throughout the year. Insulating your attic can also help prevent moisture penetration, which is especially important in humid climates where condensation can lead to mold growth and wood rot in walls and ceilings. It can also reduce the risk of ice dams in cold climates, which occur when melting snow refreezes at the roof edge. Attic Insulation Installation Experts: Energy Solutions There are several types of attic insulation available to homeowners, including fiberglass batts, cellulose, mineral wool and spray foam. The best option for your home depends on your climate, budget and the level of sophistication you desire. Fiberglass batt insulation is easy to install, affordable and a good choice for most homes. It comes in standard sizes that fit between the attic joists (usually 16 or 24 inches on center) and provides an R-value of about 38. It has a paper backing to block moisture and does not promote mold growth. Loose-fill insulation, which can be made from cellulose, rock wool, or fiberglass, is installed with a blowing machine. It offers a higher R-value per inch and does not settle, but can be more expensive than fiberglass batts. Cellulose can be a cost-effective attic insulation, but it does not last as long as fiberglass and can cause a buildup of ammonium sulfate in the attic. It also absorbs water, causing the material to weigh down over time and increasing the risk of attic sagging and ceiling cracks.
