Spray Foam Insulation

Expert Spray Foam Insulation Company Near Ashburn, Reston, Sterling

Improve your home comfort with moisture-proof spray foam insulation services

Spray foam insulation in Fairfax Station

A versatile energy-saver. 2-part spray foam expands after it's applied, creating an effective thermal and moisture barrier. Thanks to its unique properties, it can be used to solve comfort & energy problems in many parts of the house.

The insulation "team" that's supposed to make our homes comfortable and energy efficient is truly a motley crew. In the old days, sawdust was sometimes dumped inside walls to slow heat loss. Then came vermiculite - porous lightweight pebbles with the look and feel of kitty litter.

Today we still rely on an old-timer, fiberglass batt insulation that's made from spun glass fibers. But if you're looking for a star player on the insulation team, a standout with qualities that other types of insulation can't touch, it's got to be spray foam. More specifically, we're talking about closed-cell polyurethane spray foam.

Before and After
  • Ashburn VA Cantilever gets spray foam to help insulate
    Ashburn VA Cantilever gets spray foam to help insulate

    This Ashburn VA home had an uninsulated cantilever.  The external temperatures were impacting the condition and comfort in the room above.  We removed the base board of the cantilever on the outside of the house and filled the cavities with spray foam to insulate and air seal.  This will help to keep outside temperatures out and inside feeling the way the homeowner would like it to.  

  • Ashburn Va Attic Wall Insulation
    Ashburn Va Attic Wall Insulation

    This Ashburn VA attic underwent a full transformation.  After our Home Performance Sales Pro performed a no cost inspection of the home, it was determined that the attic space would benefit from air sealing, blown cellulose insulation and panel insulation used on this wall that was facing the sun for most hours of the day and required additional attention to be properly insulated.  The existing wall panel insulation was insufficient and was not air sealed.  Our production team installed the SilverGlo insulation panels and used ZypFoam to seal up the cracks in between.  This helped to create the best result to help improve the comfort ii the home and reduce the energy costs related to heating and cooling the home.  

  • Ashburn VA Attic Wall Spray Foam
    Ashburn VA Attic Wall Spray Foam

    This Ashburn VA home had a room over its garage that shared walls with a partial section of the attic.  The homeowners called us to try and help make that room and other areas of the home more comfortable.  Our team air sealed the space with Zyp Foam before blowing in more Tru Soft cellulose insulation.  There was a small wall section of the attic with framing that created blocks of open space.  Our team used Spray Foam to insulate those blocks and finish the project.  

  • Spray Foam Garage Ceiling-Ashburn, VA
    Spray Foam Garage Ceiling-Ashburn, VA

    This Ashburn, VA had rooms over the garage that were too hot in the summer.  This is can often be caused by fiberglass batts installed by the builder in the ceiling of the garage.  They fall away from the sub-flooring depleting all thermal insulating value.  This customer decided to remove the entire garage ceiling and use closed cell spray foam to fix the problem.

There are two basic types of spray foam insulation:

1-part foam: You've seen and probably used this type of spray foam, which comes in pressurized cans that are sold at home centers and hardware stores under brand names like GREAT STUFF™. This single-component foam is super-sticky, and expands at different rates (depending on the type you buy) immediately after application. Since it seals gaps as well as insulates, this product is often referred to as an "insulating foam sealant."

2-part foam: To insulate an entire basement or attic with spray foam, contractors use 2-part polyurethane foam that comes in a pair of pressurized metal containers. When both components (resin and a catalyst) are mixed together at the nozzle, a foaming chemical reaction takes place that causes the material to expand.

Spray foam advantages:

R value. Poly spray foam has a higher R-value per inch than any other commonly used insulation -R-6.2 or higher, depending on the formulation.

Air barrier: Spray foam air-seals and insulates in one step. Its ability to expand and fill gaps and cracks make it an ideal air-sealing material, and it stays in place because of its super-adhesive qualities. Spray foam is often spot-applied as an air-sealing treatment prior to filling an attic with blow-in insulation. But when applied in more generous amounts, it can eliminate the need for other types of insulation.

Waterproof: Moisture will soak its way through fiberglass and cellulose insulation, but polyurethane spray foam stops it cold. Its closed cell structure means that water can't migrate from one tiny cell or bubble to a neighboring one.

Foolproof: Did you know that a void (missing insulation) of just 5% of an insulated area can diminish overall insulation performance by as much as 50%? It's very difficult to install fiberglass insulation perfectly, so voids are not uncommon. But spray foam's expanding, super-sticky characteristics just about eliminate the possibility of voids. And once the foam cures, it's not going to settle or shift like fiberglass or cellulose can.

Spray Foam Can Be Troublesome to Apply by Yourself!

Tricky: It takes experience to get the feel of applying spray foam, especially two-part foams. With their different expansion rates and other qualities, they prove difficult for someone without experience to get the most of this material. For example, a high-expanding foam will damage a door or window jamb, but our training and experience can prevent this from happening.

Oftentimes, spray foam can also be wasted and get messy -- but our fully trained specialists know how to get the job done well the first time! 

Temperature sensitive: Cold temperatures affect the chemistry that causes the foaming action. It's critical to keep spray foam cans or two-part foam canisters within a specific temperature range for successful application.
