The Insulation Contractor is a space that often gets forgotten about until something goes wrong, such as a leak in the ceiling or a rodent infestation. But this area of your home can be an important part of the energy efficiency and comfort of your entire house. Adding attic insulation can help you reduce your heating and cooling costs by keeping the heat in during winter and out during summer.

There are several different types of attic insulation, ranging from fiberglass batts to loose fill to spray foam. Some of these types can be DIY projects, while others require professional installation. In addition to choosing the right type of insulation, it is also important to make sure that your attic is properly air sealed before insulating it.

Spray Foam vs. Fiberglass: Which Attic Insulation

Fiberglass batts are usually the most affordable and easy to install. They’re available in a variety of R-values and are ideal for most homes. However, this type of insulation can be dangerous if it becomes wet, so you should always wear a mask when handling it. Additionally, fiberglass doesn’t mix well with moisture and takes a long time to dry out.

Blown-in fiberglass insulation is similar to batts but has a higher R-value. It can be installed by homeowners with a blower rental from a hardware store, but it is recommended that professionals handle this job for you. This type of insulation can settle over time, which can decrease its insulating value.

If you choose to do it yourself, be sure to nail in depth indicators along joists or mark highly visible lines on rafters before laying loose-fill insulation. This will ensure that you achieve the correct R-value and avoid a cold spot where the ceiling and wall meet. You should also seal gaps around soffit vents and the attic entrance before installing insulation.
