Hi there from Dustin, owner of Insulation Nation! Here in So Cal, we join our Colorado office in providing personalized high touch experiences for our customers. I work with our customers directly every step of the way from evaluation, education and review of options, through the project and to inspection of the results. We've never seen less than a 5 star review. Small businesses live and die by reviews and we are ready to earn 5 stars on your project! Thank you! C-02 Insulation and Acoustic #: 1127373 EXP: 10/31/2026

"We had Insulation Nation (Dustin) come to our house to look at our attis insulation; our house was built in the late 70's and I had added more blown-in insulation many years ago. We decided on adding 8" of blown-in insulation to reduce our heating/cooling cost and to reduce the cycling of our HVAC system. They did a wonderful job of sealing any attic leaks, covers for our canned lighting fixtures, built a dam around our whole house fan, added baffles around our soffits, and added the insulation. Nicely done and a professional job. Would recommend using their service."

"The guys were really neat. They set up a tunnel from the attic to the back door. There really wasn't much to clean up after. They vacuumed out the old insullation and laid in new. It's hard to say if they did a good job in the attic, because I don’t know what its supposed to look like. They were in the attic almost about 7 hours. The only issue was that they said the senior discount on their Angie's list page must be old so they didn't honor it."

Insulation questions, answered by experts

Avoid sleeping in a house immediately after spray foam insulation is applied due to the off-gassing of volatile organic compounds (VOCs). These fumes can cause respiratory irritation, headaches, and other health issues. It’s recommended to wait 24 to 72 hours after installation to allow the foam to fully cure and the fumes to dissipate. The exact time frame depends on the type of spray foam used and the ventilation during the application, but your installation pro can advise you on the best timeline. 

The type of insulation you need in your home depends on your location, the installation site, and your region’s climate. According to Energy Star, insulation in homes in the Southern United States should have an R-value of between R30 and R60 in attics and R13 to R25 in the floors and walls; homes in moderate climates require R values of R38 to R60 in attics and R25 to R30 in floors and walls; and homes in northern states require an R value of R49 to R60 in attics and R25 to R30 in floors and walls.

A plastic vapor barrier should completely cover your basement to prevent water from penetrating through the walls. This typically goes before installing insulation to prevent moisture from building up and becoming trapped on the inside of your insulation, where it can collect and lead to mold damage. Installing insulation after the vapor barrier allows for any moisture to exit the walls for better ventilation.

Yes, crawl space insulation is worth it if installed correctly. Installing insulation in your crawl space will improve the air quality, help stabilize your home's temperature, lower your energy bills, and prevent pests from entering your home. Though you’ll pay more to install insulation initially, the savings you get from installing insulation can help offset those initial costs over time.

The best type of attic insulation depends on where you live, your budget, and what stage of construction the attic is in. For example, if you're building a house, then structural insulated panels are a worthy investment since they're easy to install during construction and they're the most energy-efficient type of insulation.  

Additionally, if you live in a very warm climate, then you can potentially save quite a bit of money by opting for reflective insulation, which is more affordable than comprehensive insulation but doesn't work well for cool climates. Blown-in, loose-fill, and spray foam insulation are all great options for attics in moderate climates.
