Air Sealing

Air Sealing for your home

We air seal the Top Plates, Chases, Wire Penetrations, Junction Boxes, Bath Fans, Tin & Heal Caulk Furnace Flues. Then we place rulers for quality controll and baffles. We use fire stop foam and fire stop cault for this. We will not use the white foam walls because of flammability issues (without any wind outside you could have a 10 mile an hour convection current of air moving up and down the walls, if so). What is common to happen is the hot air from the attic in the summer goes down the walls and heats up the house from the inside out. Then th ecold aire form the attic in the winter goes down the walls and cools the house from the inside out. By properly air sealing your home with the correct insulation practices (we’re one of the very few to do this) at the top plates, you can stop this waste of energy.

Air leakage into interior walls including plumbing or exhaust flue penetration into attic above.  Top plate air leakage present as well.

Large exhaust flue chase open to the attic above.  Dropped Ceilings also look similar.  Infrared Picture taken on cold day.

Air movement through swamp cooler and around air movement at top of wall.

Air leakage under exterior door.  Install bulb type weatherstripping or change / raise threshold.
