How Foam Insulation Affects the Construction Process
Unlike the confusing rumors you may have heard, foam does not
change your framing very much. You will save money during the
building stage, if you make the decision to use foam before
you frame. Listed below are the changes you may expect in a
foam home:
|
You do not need the BIG additional expense of 2x6’s for your
walls just to get a higher R-Value. Save the money & upgrade
your insulation to foam. |
|
Leave the corners of your walls with a bigger internal gap
when framing. Then we can better seal and insulate the corners
with foam. |
|
Use a foam gasket between the bottom plate of your perimeter
walls and your slab. This stops unwanted outdoor air
infiltration from entering. |
|
When foam insulating your attic floor, use sealed insulated
recessed lights. These housings will not allow hot or cold
moisture laden air from your attic, to enter your conditioned
living areas. Improves overall comfort levels.
|
|
If you choose to foam insulate your roof deck (a closed attic
system), you will need to eliminate all ridge vents and soffit
vents. Your attic will then become part of the thermal
envelope. It will be much cooler and cleaner.
|
|
When using a closed attic system, have the framers build
attic separation walls at the garage, carport, front and
back porches. Then we can properly seal your attic above
all conditioned living areas. |
|
Finally, a foam home does not need as much air conditioning or
heating. The average foam home will use up to 30% smaller A/C
units. One of our Energy Consultants will help you properly
size your units. |
