Fact#1 - Moisture will get into a wall system, one way or another.

Fact #2 - Trapped moisture can lead to mold, mildew, even rot.

Fact #3 - 80% of construction litigation is moisture related.

Consider the advantages of DuPont™ Tyvek® Weatherization Systems products—a relatively simple solution to a potentially serious problem. If you’re not currently using a weather resistant barrier—if you’re using building paper, #15 felt or other perforated housewraps—take a minute to see what a difference DuPont™ Tyvek® makes for building in quality protection that’s proven itself on millions of homes.

DuPont™ Tyvek® Weatherization Systems products:

• Help reduce water related callbacks
• Have the best combination of water, moisture and air infiltration protection of any other secondary weather membrane
• Is a name recognized by homeowners for comfort and energy savings
• Give a clean, crisp, quality-enhancing image on your jobsite
• Has the only local, in-the-field weatherization specialist network
• Is a leading brand backed by a trusted company

DuPont™ Tyvek® is a unique nonwoven web structure with microscopic pores, small enough to resist bulk water and air molecules, but large enough to let smaller moisture vapor molecules pass through.

DuPont™ Tyvek® creates an envelope of weather protection for all your homes. Water, moisture and air—whether from inside sources or from outside weather conditions—inevitably will find ways to get inside walls, causing homeowner discomfort and potential mold, mildew, even structural damage.

DuPont™ Tyvek® bridges the gaps and seams between building materials (a half mile of cracks in an average home) and reduces drafts that limit a wall’s effective R-value. Air infiltration can cause up to 63% loss of R-value without DuPont™ Tyvek®.

DuPont™ Tyvek®, along with proper flashing, provides added protection against water infiltration around doors and windows—some of the biggest problem areas.

Make your protective shell continuous using DuPont™ Tyvek® Tape for a secure Tyvek® to Tyvek® seam.

• Cuts down drafts and cold areas in winter
• Keeps hot, humid air out in the summer
• Protects a home long-term against possible mold, mildew, rot
• Cuts air infiltration so it cuts energy bills

The nonwoven pore size of DuPont™ Tyvek® compared to mechanical pin-perforated housewraps and #15 felt is clear. That’s why DuPont™ Tyvek® has the best combination of bulk water resistance, moisture vapor transmission and air infiltration protection.
