Most attic insulation projects have several steps in the service to improve their performance.  Removal of old insulation, air sealing and new insulation installation are some of the most common options as was the case with this Fairfax Station home.  An often added step to promote even better performance is to encapsulate the HVAC ducts in an attic with spray foam.  Metal HVAC ducts running through a hot attic in the summer or a cold attic in the winter can have trouble effectively delivering heated or cooled air created by the HVAC system.  Spray Foam insulation protects the conditioned air by keeping the ducts from allowing attic temperatures to have an impact.

Homeowners often try to get the most possible use out of the space in their home.  That can include turning small sections of attic into storage areas.  This storage space was cold in the winter and hot in the summer and the air inside was impacting the room it was attached to.  Our production team installed Silver Glo insulation panels and sealed them up with Zyp Foam.  This will better regulate the temperature and comfort for the room it is in.

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!
