Duct Sealing

Air Duct Sealing Service

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.

✕ 30% loss from positive pressure
✕ Moisture problems
✕ Conditioned air not delivered
✕ Too cold in the winter
✕ High energy bills

Why spray foam on ductwork?

Duct Sealing / Moisture Thermal Pressure Barrier at 2″ of Closed Cell Spray 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 with spray on duct insulation 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

Comfortable cozy room with direct heat delivery through sealed ducts

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.
