Proper attic insulation is the best way to prevent heat loss in the winter and retain cool air in the summer.
Traditional attic insulation.
Traditional insulation could retain water potentially damaging your home as well as reducing the functionality of the insulation.
Foam once installed is an incredibly strong adhesive so when installed in a traditional attic scenario creates a air tight thermal blanket across the ceiling of a house.
It s a sandwich of rigid foam insulation and plywood or osb oriented strand board the flaky plywood.
There are other materials and systems that you can use to insulate your attic.
Water retention can be a contributor to mold growth.
Aside from the insulating benefits of foam a large benefit is that spray foam once installed will never settle blow around or disintegrate.
But when radiant barrier is added over traditional attic insulation emissivity levels drop considerably.
Your attic insulation just shouldn t be alone.
One that i like a lot since i built a house out of them is the structural insulated panel.
Be sure to check your current insulation in case it s time for an upgrade.
So it s time to pay close attention to what s happening up there.
A short overview many homes have attics that are completely uninsulated.
Traditional attic insulation and radiant barrier work together and each do their part.
Spray foam stays in place and does not settle ensuring total continual performance.
The result is more consistent temperatures inside the living spaces throughout the winter.
You can use the small pressurized cans of foam in place insulation to reduce air leakage in holes and cracks such as window and door frames and electrical and plumbing penetrations.
The type of insulation you need depends on which type is currently installed and the required r value.
Developed in the 1930s the candy floss like insulation is the go to insulation method to date.
Foam in place insulation can be blown into walls on attic surfaces or under floors to insulate and reduce air leakage.
It isn t sufficient protection against conduction.
The most common insulation materials are fiberglass cellulose and foam.
Radiant barrier is your first line of defense against radiant heat and traditional attic insulation fiberglass or cellulose is the second line of defense against conductive heat gain.
Professionals spray an expanding foam insulation into your attic sealing the cracks and insulating it from outside temperature variations.
