Spray Foam Insulation Contractors

Spray Foam Insulation in the Washington, DC Metro Area (Maryland & Virginia Surrounding Areas)


spray foam insulationSpray foam insulation is a technologically advanced type of insulation that bears little resemblance to the insulation used over the years.

Back in the day, homebuilders used sawdust inside walls to slow down the transfer of heat. Then came vermiculite – lightweight pebbles that looked like kitty-litter which was meant to act as insulation. 

Then we moved up to fiberglass batt insulation, made from spun glass fibers. This was a step up from both sawdust and vermiculite, and has been used as insulation for many years. But closed-cell polyurethane spray foam insulation far surpasses all of these options, offering several advantages that other forms of insulation can't offer.

Advantages Of Spray Foam Insulation

1) R-Value

Polyurethane spray foam insulation has a higher R-value per inch than fiberglass batt insulation, meaning you get more bang for your buck with spray foam insulation.

2) Air Barrier

Air sealing is just as important as the insulation you use when insulating your walls and attic, and spray foam does both air sealing and insulating in one step. It works as an air sealant because it expands and fills gaps, while its adhesive quality means it stays put once it is properly in place.

3) Waterproof

Other types of insulation allow moisture to seep through, but the closed-cell structure of polyurethane spray foam insulation doesn't allow water to move from one cell to the next. No water is getting through this one.

4) Foolproof

Installing fiberglass insulation correctly is difficult, and spots can be missed – and missing a small spot when insulating can mean a lot of energy lost in the long run. Spray foam insulation expands, and is very sticky, so it is easier to make sure every small nook and cranny gets properly insulated. Also, unlike other types of insulation, spray foam insulation doesn't settle or shift. Once it cures, spray foam stays put.

Two Types Of Spray Foam Insulation

1) 1-Part Foam

Sold in hardware stores in pressurized cans, this spray foam is made of one component, is very sticky, and different brands will expand at different rates. Often called "insulating foam sealant", this type of spray foam is good for sealing gaps.

2) 2-Part Foam

Contractors use pressurized metal containers that contain 2-part polyurethane spray foam composed of a resin and a catalyst. This type of spray foam is more suitable to insulating whole basements and attics

Leave It To The Pros

Spray foams – particularly 2-part foams – have different qualities and expansion rates, and for someone who is not experienced at using them, they can be difficult to use. Our trained professionals will get the job done right, with minimal waste and mess.


Start With an Energy Inspection

Having proper insulation can help increase your comfort, save energy, and improve your home's safety and durability. But the first step is to schedule an energy inspection to find out exactly what home improvement work is recommended for your home. Our energy efficiency experts will provide detailed recommendations for your home in the Washington, DC Metro Area (including Virginia & Maryland suburbs).

Learn More About Insulation

We were unaware of what was involved in an energy audit and your audior took the time to explain everything. We were impressed with the report which told us the areas in which we need to take action on. He never pressured us to use any particular contractors, he just suggested that we go to the HomeEnergyTeam web site to select contractors of our own choice. He did an excellent job and we HIGHLY recommend the Home Energy Team Affiliates. We already have recommended them to several of our neighbors. Again, EXCELLENT JOB!

Willie Gantt

Your home energy audit proved to be very informative and helpful. I was not aware of the updraft created inside our walls because of the balloon framing construction. You said that that can cause heat to be pulled out of the house with the draft going up inside the walls and should be re-mediated. You also said that the attic insulation was insufficient and that fiberglass batts can leave spaces for around the edges causing heat loss and that it should have blown in insulation on top of what was there to seal the whole attic and increase the R factor. Thank You for all your advice and expertise. You made me aware of things I should consider and did the upgrades. I can already see the difference on my utility bills!
