Thermograms
or Thermal pictures are showing colors blue and black as
cold infiltration into a warm house
Gabled Ends: Many
builders do not insulate these area's properly causing large
amount of infiltration
Knee Walls: Even
though the attic side of the knee wall is insulated barriers
to prevent attic air from flowing into the spaces between
the studs have not been installed correctly.
Foundation Sill Plates: The wood
frame and the concrete foundation wall typically isn’t air
tight.
Hydrant Radiant
Heat: It is hard even for the installing contractor to
know if all the zones are working properly
Improperly
Installed Insulation: If the insulation isn’t pushed
against the wall board, air gets between the insulation and
the wall and ruins the effectiveness of the insulation.
Chase ways are
areas between the studs, that are used for plumbing, wiring,
ducts, and chimneys.
These areas are equivalent to an open window to the attic.
Can lights
fixtures that protrude into attics work much like mechanical
fans. Heat from the bulb rises through the fixture, creating
a draft of air.
Leaking Door and
Window Seals can be found even on new homes and high
efficiency products.
