Between the high temperatures and the powerful sun in the Las Vegas area, it is essential to have the proper amount of insulation in your attic to keep it cooler and let your air conditioner do its job more effectively. Whether you’re building a new home or upgrading the insulation in an existing one, you will need to choose the best insulation for your needs and your budget. Two of the most popular options are fiberglass and spray foam, and they both have advantages.
How Much Attic Insulation Do You Need?
For locations like Las Vegas that are in Climate Zone 3, The U.S. Department of Energy recommends insulation rated at R-49 to R-60 in the attic. The R-value of a material indicates its resistance to the flow of heat, with higher numbers representing greater performance.
The Advantages of Spray Foam Insulation
Spray foam insulation is made from two liquids that are mixed on-site and sprayed into place. It quickly expands, adhering to nearby surfaces and expanding to create a thick insulating layer that conforms to any irregularities in the installation site, such as wires, plumbing, or outlet boxes. This creates a tight air seal. There are many advantages of spray foam insulation for Las Vegas homes, including the following:
- Impressive performance of up to R-6.0 per inch of installed insulation
- A tight seal that minimizes air leaks and drafts
- More insulation can be packed into a tighter space
- It is not vulnerable to moisture, mold, or pests
On the other hand, spray foam insulation is quite expensive compared to fiberglass. It can also release harmful chemical vapors while curing, and if it is not mixed properly by a professional, it may not cure completely, extending the amount of time it emits those vapors.
The Advantages of Fiberglass Insulation
Fiberglass insulation is made from thin glass fibers that are either blown into place or manufactured into batts that fit tightly between studs, joists, and rafters. It is an economical insulation that offers good thermal performance, with between R-2.2 and R-3.8 per inch of installed insulation. The blown-in variety can easily be added to existing walls, and it can conform around objects to create a better air seal. Compared to spray foam, the advantages of fiberglass insulation include:
- Lower cost that’s better for tight budgets
- No harmful chemical vapors or worries about curing
- Fiberglass offers better fire resistance than foam
- It is more sustainable and environmentally-friendly
Fiberglass does not perform quite as well as spray foam, however, with reduced R-values and air sealing abilities. Plus, it is more susceptible to harm from compression, pests, mold, and water damage. But, when you factor in installation and material costs, fiberglass insulation can be an attractive option, and it compares well to spray foam insulation for Las Vegas homes.
