HVAC ducts likes this one in the attic of this Harpers Ferry WV are designed to deliver conditioned air (heated or cooled) from the HVAC system into the rooms of the home below.  In the summer attic temperatures and reach up to 120 degrees or higher and in the winter attic temperatures can fall well below freezing.  That means the conditioned air could be travelling through a duct that is either baking in the heat or has been sitting in freezing cold temperatures as if it were outside.  These harsh conditions can work against the efforts of the HVAC system and result in the conditioned air being less cool or hot than it needs to be to make the rooms of the home comfortable.  It also causes the HVAC system to run more than it should, running up energy bills.  Encapsulating the ducts in spray foam helps insulate them from being impacted by external temperatures.

This Harpers Ferry WVA home has an enclosed room/deck area that was too cold in the winters and too hot in the summers.  The homeowners called to see if we could help make it more comfortable.  After performing a Home Performance Inspection, our Sales Pro Jonathan was able to identify a need for better insulation below the room.  The existing batt, rolled insulation was falling loose from the flooring and had gaps where the hot and cold air from outside was able to move into the floor above. Jonathan recommended the use of spray foam to air seal and insulate the spaces between the frame for the deck/floor.  This will keep the space more comfortable and reduce the energy cost to heat or cool the room.

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. To learn more about crawl space insulation cost, call, or click today!
