4 Types of Attic Insulation and Their Advantages and Disadvantages
The attic is an often overlooked space, and many homeowners don’t bother with it until something goes wrong — usually, a leak in the roof or rodent infestation. But, attic insulation is a crucial component of any home, and it provides a host of benefits including energy savings, comfort, and improved indoor air quality.
There are several types of attic insulation to choose from, and each has its own pros and cons. To make the best decision for your home, consider the following 4 types of attic insulation and their advantages and disadvantages:
Fiberglass batt insulation is the most common type of attic insulation contractor. It is composed of slivers of fiberglass, which originally came from sand and recycled material. It is affordable, offers good thermal performance and acoustic insulation, and can be easily cut to fit around obstacles in an attic or wall cavity.
How Attic Insulation Improves Indoor Air Quality – Energy Solutions Answers
Loose-fill insulation, also called blown-in insulation, is a combination of different particles like fiberglass, mineral wool, and cellulose that are blown into attics and walls to fill gaps. It is ideal for hard-to-reach areas in an attic or wall, offers excellent thermal performance and acoustic insulation, reduces noise, and is biodegradable and environmentally friendly.
Reflective or radiant barrier insulation consists of a reflective foil layer that is attached to a substrate, such as kraft paper, plastic film, and polyethylene bubbles. It is installed in homes — particularly in attics — primarily to reduce summer heat gain and lower cooling costs.
