Tyvek® StructureGuard®


Tyvek StructureGuard – The Latest in Vapour-open Breather Membrane Technology

The high-quality membrane assures first-class air and moisture management, making it the ideal choice for modern-day architects.

DuPont™ Tyvek® StructureGuard® is the high-quality membrane assuring first-class air and moisture management. The unique material science helps keep air and water out, while letting water vapor escape.

As a result, it can contribute to improved building durability by helping to protect homes against damaging wind and rain that can penetrate the exterior cladding.

Tyvek® StructureGuard® can also reduce home energy bills by controlling air flow and water intrusion, which helps insulation work better, allowing the HVAC system to work more efficiently. It’s a house wrap engineered to keep homes cool in the summer, warm in the winter, and dry all year round.

    • Perforated Wraps

      Perforated wraps give up a great deal of resistance to air and water penetration in order to achieve some level of vapor permeability. Water and air infiltration can lead to the potential for water damage and make insulation less effective, leading to higher energy costs

    • Low Perm Microporous Film Wraps

      A low perm, microporous film wrap is manufactured in a two-part process, where a coarse fabric backing with no protection for a building is laminated with a fragile film, in order to pass minimum requirements for water and air resistance. The film layer is delicate and routinely compromised in the real world through tearing and abrasion.

    • Ease of Installation

      Tyvek® StructureGuard® is easy to install. It is pliable, so it readily wraps around corners, interfaces at joints, and wraps over unique architectural geometries.

      Light weight, easy to handle, and fast to install, Tyvek® StructureGuard® is available in 9-foot and 10-foot width rolls, to help minimize seams and offer the potential for reduction in labor.

    • How this technology works

      The unique non-woven structure of Tyvek® StructureGuard® makes it breathable, allowing moisture vapor to pass through. This helps promote drying in wall systems, to help prevent mold and water damage. In addition, Tyvek® StructureGuard® stops air movement through the walls, helping insulation perform closer to its full R-value, to provide a more energy-efficient home.
