Preventing Heat Loss
If you are having difficulty locating leaks, you may want to conduct a basic building pressurization test:
- First, close all doors to the outside, windows, and fireplace flues.
- Turn off all combustion appliances such as gas burning furnaces and water heaters.
- Then turn on all exhaust fans (generally located in the kitchen and bathrooms) or use a large window fan to suck the air out of the rooms.
This test increases infiltration through cracks and leaks, making them easier to detect. You can use incense sticks or your damp hand to locate these leaks. If you use incense sticks, moving air will cause the smoke to waver, and if you use your damp hand, any drafts will feel cool to your hand.
The Rim-Joist is often a place homes suffer from large amounts of heat loss. There is only 1.5” of lumber covered by siding that separates you from the elements outside.
A thermal imaging sensor can be used as well, to help locate places in your home where thethermal envelope is not fully enclosed and sealed.
Can fix the problems associated with excessive heat loss through the rim-joist. Since SilverGlo is a proprietary product, you can't just buy it off the shelf. Your local Basement Systems dealer will send someone out to give you a free estimate.
