When not loading the cellulose hopper in the truck, Zach volunteers for the Putney Fire Department.
Mike demonstrates dense packing a wall cavity. Netting is hung between the studs and cellulose is blown under pressure between the sheathing and the netting. Voila!
Here's a nice dense packed wall all ready for sheet rock!
Our trucks are everywhere! Here's one at a new construction job in Putney.
Chad attaches the blower door fan into a client's doorway. The fan will draw air out of the house changing the pressure differential between the outdoors and indoors. When the fan is running, air that was escaping the home under normal conditions will enter the home. The effect is the equivalent of a 25 mile hour wind hitting your home from all sides.
Time to turn on the fan and depressurize the house. Armed with his infrared camera, Chad gets ready to find the leaks.
The blower door is a fairly simple contraption, but the manometer that's attached to it is pretty sophisticated. It's calculating the air flowing through the fan in cubic feet per minute or CFM. The higher the number on the manometer the more air flowing through the fan, the leakier the home.
Now that the fan is running, Chad shows a client some leaks above her window trim using the infrared camera. The infrared camera is an invaluable tool as it reads differences in temperature. The photos identify where the cold air is entering through crevices. It's also fun at parties.
