Spray Foam Insulation Kits
The exterior of your home is called
the "envelope" or shell. The insulation, outer walls, ceiling,
door, windows, and floors all work together to control airflow in and out of
the home structure, repel moisture, and prevent heat from being lost or gained weather inside or outside the door of your home.

Always air sealing door & windows strip
before adding insulation, then sealing up holes, weather strip door, caulk pipes and wires, weather strip and insulate attic floors, basements,
and crawl space walls in your home. Any air sealing efforts will complement
your insulation efforts, and vice versa. Proper moister control and ventilation srategies will improve the effectiveness of air sealing and insulation, and
vice versa. Moldy and dusty air can enter a leaky home through such areas as
attics door strip or foundations due to weather. This air in the home could
cause health problems.
The recommended sealing strategy in both new
and old homes is to
reduce air leakage as much as possible and to provide controlled ventilation
and insulation as
needed.
Air leakage, or infiltration, occurs when outside air enters a home
uncontrollably through cracks and openings. Properly air sealing, insulation
& strip, such cracks and openings in your home can significantly reduce
heating and cooling costs, improve building durability, and create a healthier
indoor environment.
First, make a list of obvious air leaks
(weather drafts). The potential l energy savings from reducing drafts in a home
may range from 5 to 30% per year, and the home is generally much more
comfortable afterward.

Check for in door air leaks, such as gaps along
the baseboard or edge of the flooring and at junctures of the walls and
ceiling. Check to see if air can flow through these places:
·
Electrical
outlets
·
insulation
·
Door
strip
·
Switch plates
·
Window
frames
·
Baseboard
strip
·
Weather
strip around door
·
Fireplace dampers
·
Attic
hatches
·
Wall-
or window-mounted air conditioner.
Also look for gaps around pipes and wires,
electrical outlets, foundation seals, insulation, Door
strip and mail slots in your home. Check to see if the caulking and
weather striping are applied properly, leaving no gaps or cracks, and are in
good condition.
Inspect windows and doors for air leaks. See if
you can rattle them, since movement means possible air leaks. If you can see
daylight around a door strip or window frame, then the door or window leaks. You can usually seal these
leaks by caulking or weather strip them. Check the home storm
windows to see if they fit and are not broken. You may also wish to consider
replacing your old windows and door(s) with newer, high-performance ones. If
new factory made door strip or windows are too costly, you can install low-cost
plastic sheets over the windows insulation.

If you are having difficulty locating weather
leaks, you may want to conduct a basic building pressurization test: Home Blower Door test
