Why Is Insulating An Attic Important?

Insulating an attic is important because it creates a vapor barrier, thus acting like a blanket around your building structure. When it comes to choosing the right type of attic insulation, spray foam is one of the best options because cellulose or fiberglass insulation will still allow air to pass through it, and is not capable of creating a complete air seal.

Types of Insulation For Attics

There are many types of attic insulation that you can choose from. Some of the most popular ones are as follows.

  • Cellulose insulation:  Cellulose insulation is not expensive and is a popular choice for attics. It has an R-value of 3.5 per inch. One disadvantage of using cellulose is that it allows air to pass through it. As a result, it will not completely seal your building envelope.

  • Fiberglass insulation:  Fiberglass is also a popular choice and comes in the form of batts and rolls and loose fill. Loose-fill fiberglass has an R-value that is R- 3.5 per inch whereas batts have an R-value of 2.5 per inch. Fiberglass is a good option but has disadvantages as well because if it is disturbed, the tiny glass particles will escape into your home and cause skin and respiratory issues.  Fiberglass also allows moisture to pass through it. Thus it may lead to moisture retention and mold and mildew issues.

  • Spray foam insulation:  Foam insulation is one of the best types of insulation for attics as it forms a complete air seal. This completes the building envelope and conditioned air will not be allowed to exit through the roof. A good insulation contractor will advise you regarding using open-cell or closed-cell spray foam depending on what kind of attic you have.

  • Radiant barriers: Radiant barriers reflect the sun’s heat and help to cut down on cooling costs. They are relatively easy to install and an effective method of keeping your home cool especially if you live in a sunny region. You can combine radiant barriers with other insulation types, such as spray foam or mineral wool.

Why Hire an Insulation Contractor?

Only a professional insulation contractor can install insulation in an attic efficiently and correctly depending on the type of attic you have. They will check for blocked vents, air leaks, and damaged insulation if you already have old insulation. Attic insulation that is installed properly by a professional will last a long time.
