The Different Kinds of Attic Insulation Material

Attic insulation is an important part of today’s roofing as it helps reduce the heat absorbed by your roof. The right kind of insulation makes the roof less susceptible to the bad effects of trapped heat. It also helps reduce indoor cooling requirements, which leads to energy savings. As one of the leading licensed roofers in Central Florida, Universal Roof and Contracting shares with you the different types of attic insulation material.

The Different Kinds of Attic Insulation Material

Fiberglass Batts

Fiberglass insulation is typically sold as batts made of fiberglass wool. This is favored by DIYers rather than professionals because it’s readily available in stores and does not require tools to install. One can simply unroll a layer single or multiple layers on the attic floor. It’s not the ideal type of attic insulation, though, as the layers have gaps that still allow heat to seep through. If you intend to use the attic for storage or as a living space, this type of insulation will prevent you from doing so.

Loose-Fill Fiberglass

Like fiberglass batts, loose-fill fiberglass is installed on the attic floor. However, it requires a blower to install, taking DIY out of the equation. It has slightly better insulation performance than fiberglass batts. Since it’s installed on the attic floor, performing attic and roof inspection can be difficult.


Cellulose insulation is made from treated recycled paper. One of the main advantages of cellulose insulation is that it can be installed right under the roof deck, making it a good option if you need to make use of the attic space. It requires a specialized type of blower that mixes a small amount of water as it’s blown in, resulting in a tightly-packed layer of material that dries within a day. Its insulation performance is substantially superior to fiberglass.

Spray Foam

Spray foam is made from isocyanate and polyol resin. When sprayed on the target surface, it expands up to 60 times its liquid volume, filling even the hard-to-reach spaces in the attic. Spray foam can be installed on the attic floor or the roof deck, and is the most effective insulation material available today.
