Before and After Pictures from Mc Lean
Basement Floor Insulation in Mc Lean, VA

Basement Floor Insulation in Mc Lean, VA

Before After
Basement Floor Insulation in Mc Lean, VA Basement Floor Insulation in Mc Lean, VA

Sleepers and Subfloor were installed above concrete slab in a Mclean Home.

Fiberglass batts had been installed but were ineffective and drafty.  We used injection foam to fill these floor cavities above the slab with foam to air seal and insulate the floor system. 

Here you can see holes drilled on one side of the room that were the areas where we inserted the foam.  Outlet holes on the other side of the room were used as outlets for the foam and demonstrated total cavity fill when foam "Squirted" out.

This home is now much more comfortable and energy efficient.

Home Insulation Services You Can Trust!

Comfenergy is Nova'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 with out patented home insulation solutions.  Did you know that most modern homes do not have adequate insulation?

We offer a wide variety of home insulation products and services, and each one serves it's 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!
