In most wall applications, you will use r-13 or r-15 kraft-faced fiberglass insulation rolls for these two-by-four stud walls. While rated differently, these two types of insulation are close enough in thickness that they can both fit into modern two-by-four wall systems.
What Type of Insulation for Walls?
There are many types of insulation for walls, and the best type of insulation for your home depends on several factors.
The climate in your area, the type of home you have, and your budget all play a role in deciding which type of insulation is best for you.
In general, there are three main types of insulation for walls: fiberglass, cellulose, and spray foam. Each has its own advantages and disadvantages, so it‘s important to do your research before making a decision.
Fiberglass is one of the most popular types of insulation. It‘s made from glass fibers, and it‘s very effective at preventing heat transfer.
Fiberglass is also relatively easy to install, and it‘s relatively inexpensive. However, fiberglass can be itchy and uncomfortable to work with, and it‘s not as effective as some other types of insulation in very cold climates.
Cellulose is another popular type of insulation. It‘s made from recycled paper products, and it‘s very effective at preventing heat transfer. Cellulose is also relatively easy to install, and it‘s relatively inexpensive.
However, cellulose can be difficult to work with, and it‘s not as effective as some other types of insulation in very cold climates.
