duct sealing

Duct sealing seams delivering hot air to living spaces prevent wasted gas up to 30%

Ductwork Seams Leak Positive Pressure Air Resulting In Loss Of Pressure And Lower Temps Further Down The Delivery Lines To Vents In Bedrooms, Bathrooms, Kitchens, And More

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

Comfortable Cozy Room With Direct Heat Delivery Through Sealed Ducts

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.
