Why Duct Seal
With Foam?

Get above and beyond efficiency from your heater when you seal duct work with foam.  

Ducts are inherently leaky because of joints and gaps, and sealing the duct work will help make the insulation as effective as possible. 

This means the air you pay to heat must pass through cold ductwork, where it will cool off, forcing your furnace to run longer

Duct Sealing Delivers Better
Temps By Preventing Leaks.

  1. A combination of closed cell spray foam and cellulose insulation is the perfect pairing for an unconditioned attic ( vented attic ).
  2. Seal the attic floor and any ductwork with one part spray foam around seams or two part spray foam around duct trunks and delivery lines. 
  3. Duct sealing can be done with from inside the duct for lines traveling through conditioned spaces where thermal transfer is not a concern.  

Before Spray Foam
On Ducts

The most common insulation materials fiberglass wrapped poorly around ductwork, it is a skin and eye irritant, does not seal seams, the warm moist air condenses. Ductwork should be insulated properly. 

After: Ductwork Sealed
with Spray Foam

A disconnected duct can cause heat loss and condensation in the attic and condensation in the ductwork. 

Air conditioning ducts should have their air/vapor barrier on the outside. = closed cell spray foam. 

Heating ducts duct serves as the air/vapor barrier.

If you are looking for a company that couples outstanding work with outstanding customer service, then Green Attic Insulation is who you should definitely call. I truly wish I would have called them years ago as I have been putting off suspected issues that centered around extreme temperature fluctuations between winter and summer, along with poor ventilation, within my attic.

James is prompt, thorough, and personable -- responded to my website inquiry right away and made it easy to schedule an appointment (still haven't heard back from the competition -- that was three days ago). He provided a detailed and professional quote within minutes of being on site and saved me from spending $20k on an unnecessary new roof! I'm glad I contacted Green Attic.

Highly recommend! Green Attic is thorough, responsive, and professional. Although it has only been a month since we had the work done, the results are clear. Our house is more comfortable, while our gas consumption is down ~30% and electricity is down ~25%.
