A building envelope is the physical separator between the inside and outside environment of a building, protecting it from the air, water, heat, light, and noise outside – this is an essential line of defense against the elements and wasted energy. Arroyo carries Dupont Tyvek products that make buildings more durable, comfortable, and energy-efficient.

Tyvek provides you with solutions that meet or exceed codes, helping to extend building life and assisting in the reduction of fossil fuel consumption. They resist moisture and air, but are highly permeable to reduce the risk of water damage, mold growth and wood rot.

FlexWrap NF self adhered flashing does not require mechanical fasteners, even in flexed corner areas around building openings. This allows it to provide easy, one-step insulation for hard-to-seal corners around windows and doors.

FlexWrap NF is designed to help protect vulnerable corners against air and water intrusion. It’s effective across a range of window and door designs and a wide range of typical wall substrates, including OSB, plywood, gypsum, concrete masonry unit (CMU) and other non-nailable sheathing materials.

Tyvek HomeWrap is the original house wrap, incorporating unique material science that 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 HomeWrap 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.

Tyvek StuccoWrap has an engineered, grooved surface – it’s a stucco wrap designed to be installed as a drainage planebehind stucco facades and EIFS systems.

Tyvek CommercialWrap D provides superior air and moisture control, with an emphasis on enhanced drainage. It combines the unique material science of Tyvek weather barriers with a vertically grooved surface to help channel windblown rain and other bulk water.

Utilizing a specially engineered, “creped” surface texture, Tyvek CommercialWrap D is designed with an enhanced drainage plane to help meet the challenges of heavy rainfall, windblown water, snow and humidity, and provide effective drainage. By combining superior air infiltration and exfiltration control, bulk water holdout, and vapor permeability, Tyvek CommercialWrap D helps prevent water intrusion and accumulation in the wall, which can lead to mold and water damage.
