Floor Insulation

Warm Up Your Floors With Proper Insulation Near Sterling, Leesburg, Ashburn

Spray Foam in the crawl space in Leesburg

Spray foam insulation will keep your ground from losing heat to the basement or crawlspace - and seal air leaks, too.

Ground level floors may get too cold in the winter if the spaces beneath them are cold. Existing insulation (if there is any) is often inadequate or improperly installed beneath the floor boards. Floor surfaces cool as the heat they contain is literally sucked away. Drafts cool floors, too.

As heated air escapes from the upper levels of your home, cold air is drawn in through cracks around lower level windows and doors, from below the floor, and from outdoors. The cold air is heavier than warm air, so it tends to hug the floor and cool its surface.

Insulating the floors in your home will reduce drafts and help you save each year on energy costs!

Finding the Best Solution

Garage Insulation in Fairfax

Floors over garages are almost always cold but with our dense-pack cellulose insulation, that's a thing of the past.

When possible, convert the space below your floor to a conditioned (warm) space. For example, by insulating basement or crawlspace walls with the proper insulating material, those spaces will become much warmer and so will the floors above them. See basement insulation and crawlspace insulation for more information.

When it's not possible to insulate the walls of your basement or crawlspace, ask us about insulating the joist bays (spaces between joists) under the floor. We have various types of insulation materials that can do the job, including spray foam and rigid foam.

Our installers will pay special attention to critical areas, such as perimeter rim joists - a notorious source of air leakage.

Whichever option you choose, it should be accompanied by a thorough air-sealing of your home. Air sealing reduces the stack effect that is continually trying to expel air through small openings all throughout the upper reaches of your home, while it pulls in air through gaps around the lower levels of your home. See air sealing for more information about this Comfenergy service.

Cold floors above garages, balconies, and porches

More tips for warmer toes

  • Vinyl, carpet, cork, and wood feel warmer than ceramic tile, stone, and concrete.
  • Install glass doors on your fireplace.
  • Where feasible, supply outdoor combustion air to your furnace or boiler. Drawing combustion air from your basement or utility closet creates drafts.
  • Weatherstrip your windows and doors, especially the gaps between the bottom of exterior doors and the thresholds.
  • Wear warm slipper and socks!

Ground level floors aren't the only ones that can get cold. Rooms built above garages are notorious for having cold floors due to lack of insulation and so is any floor that's cantilevered (overhangs the foundation perimeter).

balconies, bow and bay windows, and bump-outs are all examples of cantilevered spaces. Their floors are especially prone to air leaks because of ill-fitting soffits (boards used to seal under the overhang) combined with direct exposure to wind. Comfenergy has detailed solutions for each and every situation.

We will specify the most appropriate insulation solution based upon you home's construction and your budget.
