No matter where you're building and no matter what season it is,
Tyvek® HomeWrap can help make your home more comfortable
and energy efficient. In cold weather, Tyvek® helps keep the
cold air out and the heat in. In warm weather, it helps keep the
air conditioning in and the hot air out. And by reducing the
amount of heat and air conditioning lost through cracks and
seams, Tyvek® helps save on your energy bills.
TYVEK® HomeWrap will:
Reduce airflow through the wall
Help prevent moisture buildup in the wall cavity
Provide resistance to water penetration
Exhibit better longevity than caulking
Help protect the structure from the elements during the construction phase
How Insulation Works:
Trapped air is an excellent insulator. As long as the air is NOT
MOVING. The double pane windows in your home or a Thermos
bottle are two good examples of how trapped air acts as an
insulator to keep what's inside warm or cold.
Wall insulation works the same way. As long as the air inside
the insulation stays still and dry, the insulation works to its
rated R-value. The result is a comfortable home.
But, an average 2,500 square foot home has more than 1/2 mile
of cracks and crevices in the wall cavity and if the wind blows
even a little (and it blows, on average, 8 mph across the US),
air is forced into your home. Your heater or air conditioner will
run more often to keep you comfortable, resulting in higher energy
bills.
How Tyvek® Works:
For 15 years, Tyvek® HomeWrap from DuPont has made
over 2 million homes more energy efficient and more comfortable.
Tyvek® reduces the movement of air into your home and also helps
keep water (from driving rain, for example) out of your walls.
Tyvek® HomeWrap can breathe, too (like Goretex clothing).
That means that if moisture does get inside your walls Tyvek lets
it pass through to the outside.
Helping to keep air and water out; letting moisture vapor pass
through--it's the perfect way to keep you comfortable year round!
