Healthy Home Exterior Wall Cavity Design

The roofing underlayment solution included both SlopeShield Plus SA Self-Adhered and VaproMat. Together this combination will promote air flow under the cedar shingles helping to extend the life of the roof.

WrapShield SA Self-Adhered membrane was chosen as the wall air and water resistive barrier solution. Because WrapShield SA is both breathable and air tight it stops air leakage and provides exceptional water holdout and breathability promoting a healthy home environment.

Windows Are The Most Vulnerable

A new Texas home suffered extensive moisture damage - “the windows were suspected to be a contributing factor” typically due to “inadequate weather barrier and window detailing.”

Insufficient Drainage in the Wall Cavity

An incorrectly installed stucco system caused massive deterioration and biological growth within 12 months.

Windows Require Proper Flashing

Proper detailing around windows requires a shingle overlap and high performance waterproof flashing material. VaproShield offers a complete system of flashing materials.

Rainscreen Drainage Cavity

By leaving a small air flow cavity behind the cladding, created by mesh or battens, residual water can drain away from your home. This is called rain screen design, a proven method to keep the wall cavity dry.

• Reduce moisture-related problems (mold, mildew, rot) in wall cavities by allowing vapor and moisture to escape instead of being trapped in the wall/roof
• Increase healthy airflow throughout the home helping to reduce allergens
• Save energy by installing a continuous air barrier
  around the home (roof and walls)
• Commercial-grade product (millions of square feet installed) with proven success in all climates and conditions

When homeowners opt for open-joint veneers, the exposure to sun and rain behind the joints is inevitable.
