Which Is the Best Type of Attic Insulation for Your Home?

Sufficient attic insulation can prevent energy loss and give you savings on heating and cooling costs. While it’s possible to fill holes in your insulation, it will be better to just get a replacement if it’s reaching the end of its life. To determine which type of insulation is best for your home, you should know what R-value is recommended for your location.


Trusted roofing and siding contractors help you choose which type of attic insulation is best for your home.

Loose-Fill Insulation

This type of insulation is great for attics with minimal headroom and various obstructions like vents and crossbeams. Loose-fill insulation can be blown over existing insulation and comes in fiberglass, cellulose and mineral wool. The most effective material is cellulose, which has an R-value of 2.2 to 3.8 per inch. However, mold can grow on this material if exposed to moisture.

Sprayed Foam Insulation

Sprayed foam insulation offers one of the highest R-values, which is 3.5 per inch for open-cell and 6.5 for closed-cell. These cells are made with polyurethane. Closed-foam cells are filled with a gas that allows the foam to expand and fill spaces around it. Meanwhile, open-cell foam cells are packed with air, giving it a spongy texture. Keep in mind that this type of insulation is best applied by a professional. At DryTech Roofing LLC, we’re not only known siding contractors but also attic insulation installers.

Blanket Insulation

Blanket insulation can come in either batts or rolls. It’s available in different materials including fiberglass, mineral wood, natural fibers and plastic fibers. This type of insulation is recommended for attics with standard spaced beams and joints and few obstructions.
