High Performance Construction - Air Infiltration
a normal unsealed, wood framed house, 45% of the air infiltration comes where
wall meets the floor, 27% where ceiling meets the wall, 11% from exterior window
framing, 13% from electrical outlets on the exterior walls, 3% from pipe and
wire penetrations and 1% from exterior doors. To minimize these air infiltration
paths, Quail Homes applies Owens Corning EnergyComplete Whole Home Insulation
and Air Sealing System. See photo to the left of Owen Corning sealing foam application. EnergyComplete
sealants help improve indoor air quality by helping to seal out allergens
and pollutants. The sealant also helps prevent moisture from entering walls
to reduce conditions that can lead to mold growth. By blocking gaps and holes,
you have a first line of defense against insects, rodents and other pests that
can cause health problems for your family.
Insulating ceilings, walls, and floors decreases the heating or cooling needed
by providing an effective resistance to the flow of heat. Insulation saves money.
Besides insulation and EnergyComplete sealant, Du Pont Tyvek air barrier house
wrap and metal flashing in strategical location also play an very import part
in stopping air and moisture infiltration into your home.
To qualify for Earth Advantage Platinum Certification, each new house constructed
by Quail Homes has to pass the whole house and ductwork blow test for air leakage, see photo to the right,
and a third-party energy inspection.
