Dallas Home Blower Door Testing & Home Weatherization

Blower door testing

is the most practical way to find air leaks, measure the air tightness of a building and calculate the minimum ventilation requirements to ensure acceptable indoor air quality in homes. A blower door is a powerful fan that mounts into the frame of an exterior door with a calibrated manometer constantly measuring the pressure of the home while the blower door is running. A blower door is used to pressurize a home by blowing air into the home or depressurize a home by sucking air out a home. Blower door depressurization is the most common procedure because air comes in to the home through air leaks and allows you to feel, view ( Infrared camera ) and locate the air leaks. The blower door data also allows Perkins Inc. to determine the effectiveness of any air-sealing procedures.

Home weatherization

is the process of reducing energy consumption and increasing comfort in a home by sealing air leak issues and improving the homes air barrier. Air leakage in a home represents 5% to 40% of the space-conditioning cost. Air leaks in most existing homes add up to an open window in your home 24 hours a day, all year long. Controlling air leakage is one of the most important functions of home weatherization. An effective air barrier prevents most air leakage as well as convection. An effective air barrier surrounds a home on all sides, adjacent to its insulation. However Most homes have a flawed air barrier that can be significantly improved by a blower door test and air sealing.

Home weatherization includes sealing bypasses (cracks, gaps, holes), especially around doors, windows, pipes and wiring that penetrate the ceiling and floor, and other areas with high potential for heat loss, using caulk, foam sealant, weather-stripping, window film, door sweeps, electrical receptacle gaskets, and so on to reduce air infiltration. Weatherization can also include replacing older windows with Energy Star vinyl replacement windows with insulated and Low-E coated glass as well as replacing old drafty doors with tightly sealed and insulated doors.
