Best Attic Insulation Types

When you invest in attic insulation, you’re looking for a good R-Value, a measure of the material’s ability to stop heat from escaping your home during winter and keep it inside during summer. The higher the R-Value, the more energy savings you’ll see and the cozier your home will be. Go here desertsprayfoaming.com

Fiberglass batt insulation is an affordable option that provides a high R-Value. Its drawbacks are that it doesn’t work well in damp areas and that the vapor it releases can be harmful to your health, especially if you suffer from allergies. Additionally, fiberglass deteriorates over time and can’t be removed easily should it get wet.

Cellulose insulation is an eco-friendly alternative to fiberglass that’s made from recycled paper and has fire-resistant additives. It’s denser and more airtight than fiberglass, offering superior R-Values and insect prevention. However, it doesn’t mix well with moisture and may require more maintenance as a result. Additionally, removing this type of insulation is more labor intensive as you have to pick it up piece by piece.

How Attic Insulation Improves Comfort and Reduces Bills

Spray foam insulation is becoming increasingly popular because of its exceptional R-Value and air sealing capabilities, as well as its mold and moisture resistance. It’s usually 2-3 times more expensive than the other insulation types on this list, but it will likely last longer and reduce your energy costs. It comes in open and closed-cell varieties that differ in their insulating properties. Open-cell spray foam is lighter and can break or “pop” as it expands before setting, making it easy to remove if necessary. Closed-cell spray foam is a bit more expensive but offers the best R-Value on this list at up to R-6.4 per inch.
