Air Sealing

In order to ensure indoor comfort, it is critical that you control the air leakage of a home. Even if you do a great job insulating the home, air can still leak out through holes and cracks in the building envelope and you lose your valuable conditioned or heated air. Think about wearing an insulated coat on a cold winter day, now unzip that coat.  How do you feel?

Some traditional insulation products help reduce air infiltration, but many times these products are not enough on their own to get a house to pass the blower door test. There are many options available to help air seal a home, and one of the new resources we have utilized with great success is the AeroBarrier™ aerosolized air-sealing system installed by New England Air Barrier, LLC.  This system allows precise control over the air tightness of the building envelope and guarantees results.

Installed just after plaster, this system allows you to pass the blower door test before installing interior trim.  Typical installations take just a day or two and work can resume as soon as they are done since there is no off-gassing or chemical reactions. With the air sealing out of the equation, the entire spectrum of insulation products are on the table including all fiberglass batt installs. This allows us to help you find the best mix of products to fit your financial and performance goals.

We have partnered with New England Air Barrier, LLC to afford our clients a seamless way to pass the blower door test early in the project.  We know you are under pressure to deliver your house and New England Air Barrier, LLC has been delivering results to our clients, saving them time, money, and worry over the uncertainty of the blower door test.  Check them out at
