Typical House Leaks On a typical winter day, cold outside air -being relatively dense and therefore heavy- pushes its way into lower areas of your house and displaces the relatively buoyant warm air, pushing it up to the ceiling, forcing it out through ceiling (or attic) bypasses. It is easy to detect the cold air flowing into your house -you can feel it. What is less obvious is is the warm air leaking out! You can't see it, and you can't feel it -unless you spend time in your attic. Remember, the cold air leaking in is equal in volume to warm air leaking out! In cold climate areas such as Minnesota, this warm air often reveals itself in the form of Ice Dams, and/or snow melt on roof tops. It is VERY IMPORTANT to SEAL these BYPASSES (air leaks) BEFORE adding insulation. Generally, the most effective way of keeping cold air from leaking in is to keep warm air -air you have paid to heat- from leaking out! These air leaks are best revealed using an infra-red (thermal) camera.© |
