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!
