This home in Fairfax VA had a multiple stage project to make the home more energy efficient and more comfortable.   One step was the encapsulation of the HVAC duct system in the attic with Spray Foam.  The existing ductwork had several holes at the joints where air was allowed to escape, making the HVAC system less efficient and requiring it to work harder and create more conditioned air.  The spray foam covering it protects the air from escaping and keeps attic temperatures from impacting the conditioned (cooled/heated) air travelling inside.  This will reduce the amount of energy used by the HVAC system and allow for better passage to the rooms it was intended to reach.

This home in Fairfax VA had roof leaks that were allowing water and excessive moisture into the attic which resulted in the early stages of mildew and mold.  We developed a project to help fix the attic that involved several steps and coordinating around other services providers that would eventually fix the roof, remove and clean any mold and then paint the inside of the attic after we removed all of the existing insulation.  Once painted and ready for new insulation, we used Zyp Foam to air seal the attic floor before finally blowing insulation in to cover the surfaces and properly insulate the home.

Home Insulation Services You Can Trust!

Comfenergy is Northern VA's preferred home insulation and air sealing services company. We have helped many homeowners not only reduce their home energy bills but improve the overall comfort of their homes without patented home insulation solutions.  Did you know that most modern homes do not have adequate insulation? Because of this, your home may feel drafty or uncomfortable throughout the year, mostly in the summer and winter, and this can increase your home energy costs. Proper insulation in your home allows your heating or air conditioning systems to work more efficiently which will save you money. 

We offer a wide variety of home insulation products and services, and each one serves its own unique purpose.  Our most popular form of insulation is spray foam.  Spray foam insulation is extremely versatile and can be used almost anywhere in your home.  Spray foam insulation is one of the best ways to lower energy costs, sometimes 30% or more!

Along with spray foam, we use many other different types of insulation as well. Some of our other insulation products include rigid foam, blown-in, cellulose, fiberglass, radiant barrier, and much more.  We understand that insulation is only part of the home energy and comfort equation, so because of this, we can insulate any area of your home.  We insulate spaces such as attics, basements, crawl spaces, walls, floors, garages, and much more.  If your home is uncomfortable or energy bills are too high, contact us today for a FREE home insulation quote!

Radiant Barrier for Comfort and Storage

A radiant barrier should always be a part of a home's insulation system. It functions to reduce temperatures in the attic by reflecting heat away. Radiant barriers are installed around the joists, roof beams, and wall studs - when combined with other insulation services, your attic can become a conditioned space. 

Besides comfort, installing a radiant barrier can allow you to use your attic for storage, because the heat will no longer damage your belongings. Radiant barriers can lower attic temperatures by up to 30 degrees. An insulated attic will also keep humidity lower, preventing moisture or mold damage to your things as well.
