Attic Insulation Types :


When it comes to home insulation, the attic is one of the most critical areas to focus on. This is because a poorly insulated attic can lead to significant energy loss, causing your energy bills to skyrocket. In this article, we will discuss different attic insulation types to help you make an informed decision for your home.

Fiberglass Insulation

Fiberglass insulation is one of the most commonly used types of insulation in attics. It is affordable, easy to install, and highly effective. Fiberglass insulation comes in two forms: batts and blown-in. Batts are pre-cut fiberglass sheets that fit between attic joists, while blown-in fiberglass is installed using a machine that blows the insulation into the attic space.

Spray Foam Insulation

Spray foam insulation is a highly effective insulation type that is ideal for attics. It is made of polyurethane foam, which expands to fill every nook and cranny in the attic, creating a highly airtight seal. Spray foam insulation is more expensive than other types of insulation, but its energy-saving benefits make it a worthy investment.

Cellulose Insulation

Cellulose insulation is an eco-friendly insulation type made from recycled paper products. It is blown into the attic space using a machine, and it is highly effective at preventing heat loss in the winter and heat gain in the summer. Cellulose insulation is a bit more expensive than fiberglass insulation, but its energy-saving benefits make it a wise investment in the long run.

Radiant Barrier Insulation

Radiant barrier insulation is a type of insulation that reflects heat back into the attic space. It is made of a reflective material, such as aluminum foil, and it is installed on the underside of the roof rafters. Radiant barrier insulation is highly effective at reducing summer heat gain, making it an ideal insulation type for homes in hot climates.


What is the best type of insulation for my attic?

The best type of insulation for your attic depends on several factors, such as your budget, climate, and personal preferences. Fiberglass insulation is a good all-purpose option, while spray foam insulation is ideal for those who want maximum energy savings.

How much insulation do I need in my attic?

The recommended amount of insulation for attics varies depending on the climate zone you live in. In general, it is recommended to have at least 12-16 inches of insulation in your attic.

Can I install insulation in my attic myself?

While it is possible to install insulation in your attic yourself, it is recommended to hire a professional to ensure proper installation and maximum energy savings.


Attic insulation plays a critical role in keeping your home comfortable and energy-efficient. By choosing the right type of insulation for your attic, you can save money on energy bills and reduce your carbon footprint. Consider the factors discussed in this article and consult with a professional to determine the best insulation type for your home.
