Expert Spray Foam Insulation Company

At one point pink fiberglass insulation was the best option for home insulation. However, today spray foam insulation is the much better option. Spray foam insulation has several benefits and beats the traditional fiber-glass product in every way. Spray foam insulation is the top choice for homeowners, contractors and building scientists (the experts who study home energy performance) for several reasons. Here are the top reasons spray foam insulation should be your number 1 choice:

Advantages of Spray Foam Insulation:

  • Provides both insulation and air sealing
  • Fills gaps and cracks
  • High R-value
  • Speedy installation
  • Spray foam won't shift, settle, or fall out of place

Help Your Home with Attic Insulation

Upgrading your home’s attic insulation is a very effective & popular energy-saving method because there is usually a lot of room for improvement. Most homeowners believe their attic has enough insulation but once we explain how much insulation is actually needed to make your home efficient people understand that they don’t have anywhere near enough. It is common knowledge that hot air rises which is why a properly insulation attic is one of the most important things you can do for your home. By adding attic insulation to your home you are guaranteeing to save money and also have a more comfortable home. Not having a properly insulated attic is equivalent to constantly leaving one of your windows open. Don’t wait any longer to learn more about the attic insulation methods we have available in your area!.

Crawl Space Insulation Experts

Do you need crawl space insulation installed or replaced? If so, you're in the right place! A damp crawl space with falling or sagging insulation usually means the space has a moisture problem. If that is the case our team of experts can provide a vapor barrier to keep moisture out of your crawl space. We can then replace your existing insulation with a better option such as rigid foam or spray foam insulation. If your crawl space is completely missing insulation then your home is most likely cold and drafty. This is because the environment in your crawl space will transfer to other parts of your home, which is why proper crawl space insulation is essential to keeping your home comfortable and your energy bills low.

Hot Upstairs Bedrooms - Dumfries, VA

A Dumfries, VA homeowner had been dealing with hot upstairs bedrooms in the summer months for years. He tried replacing the A/C and got an attic fan, but nothing worked. He heard about Comfenergy from a friend, and gave us a call. 

Our estimator arrived at the house and noticed that the air ducts were going through the hot attic, making the cool air traveling through them warm. He also found several air leaks in the home and very little insulation. The hot summer heat was penetrating the barely there insulation, heating up the drywall, and then radiating down into the bedrooms. Imagine putting cold air in a box with an 125 degree F roof and expecting it to stay cool. 

We installed a radiant barrier in the attic of this home, which can slow the transfer of heat and reflect heat back to it's source. We also air sealed it and insulated it with cellulose. We also sealed and insulated the duct work with closed cell spray foam. 

Once the work was done, the Dumfries, VA homeowner was extremely pleased. He reduced his AC expenses by over 10% and enjoyed much cooler bedrooms during the summer months.
