Delta Vent SA

Delta Vent SA is a gray, vapor-permeable, self-adhering air and moisture barrier that enhances the building enclosure by increasing airtightness and energy efficiency. Designed for applications in exterior walls in energy-efficient constructions, beneath final cladding systems.

Key Features

• Fully adhered without fasteners to prevent leaks
• High vapor permeability allows moisture diffusion
• Lightweight, tear-resistant, and easy to install
• Complies with ASTM standards for air barriers and nail sealability
• Self-adhering WRB and air barrier with the security of a self-adhesive edge lap
• Available sizes: 4' 11" x 115’, 9.75” x 115’, 19.5” x 115’

Delta Vent S

Delta Vent S is a black, water-resistant, vapor-permeable air barrier membrane designed to protect structures from wind-driven rain and snow while allowing trapped moisture to escape. Exterior walls, energy-efficient construction, and moisture protection in various climates.

Features

• Waterproof and tear-resistant
• High vapor permeability for efficient drying
• Maximizes airtightness for improved energy efficiency
• Protective fabric layer to prevent damage during installation
• Fabric layer on the lower side to protect the WRD against damage
• Matte black; prevents blinding during installation
• Lightweight; easily lined up and unrolled
• Large roll size to simplify installation and maximize productivity

Delta Fassade SA

Delta Fassade SA is a black, UV-resistant, vapor-permeable membrane designed for open joint rainscreen cladding systems. Its durable construction improves building performance and energy efficiency. Buildings under IRC, Type V-B construction, and IBC codes, including structures up to 40 feet tall without plastic foam insulation.

Features

• Self-adhering with high-tack adhesive for secure application
• Engineered for UV exposure in open-joint cladding
• Lightweight, watertight, and highly tear-resistant
• Matte black finish enhances appearance and reduces glare during installation
• Acts as a blank canvas for open cladding architecture
