Are you a home builder, contractor, architect, or homeowner striving for superior building performance? Facing challenges with moisture intrusion, compromised indoor air quality, or struggling to meet stringent energy efficiency standards in your construction projects? The integrity of your building envelope is paramount. Without a robust defense against air and moisture, your structures are vulnerable to costly issues like mold, mildew, and significant energy loss.

At Spycor Building Resource Hub, we understand these challenges. That's why we're highlighting DELTA®-VENT SA, a revolutionary vapor-permeable, self-adhering air- and water-resistive barrier (WRB) designed to provide a comprehensive solution for a high-performance, energy-efficient, and healthy building enclosure.

DELTA®-VENT SA: Advanced Product

Details for Superior Protection

DELTA®-VENT SA is engineered for excellence, acting as a critical component in safeguarding your building. This 3-layer, self-adhered membrane actively prevents exterior moisture from entering your building while allowing moisture vapor from within to escape, effectively mitigating mold risk and enhancing energy efficiency.

Key Features & Benefits:

• Self-Adhering & Seamless: Features a full-surface, aggressive adhesive coating and a unique self-adhering edge lap, ensuring a 100% watertight and airtight seal without the need for fasteners in the field of the membrane. This eliminates fastener leaks and reduces labor.
• High Vapor Permeability: With an industry-leading perm rating of 50 perms (ASTM E96-05, Proc. B), DELTA®-VENT SA allows the building to breathe, preventing moisture accumulation within the wall assembly.
• Robust Air Barrier: Dramatically exceeds the stringent requirements of the Air Barrier Association of America (ABAA) and the National Building Code of Canada (NBC 2010, 2015, 2020), achieving an air leakage rate of <0.2 L/(s·m²) @ 75 Pa. This significantly improves energy efficiency by preventing uncontrolled air leakage.
• Exceptional Durability: Made with high-strength spun-bonded polypropylene (PP) fabric outer layers thermally bonded to a watertight TPU middle layer, it's lightweight, tear-resistant, and can withstand harsh job site conditions, wind, and weather.
• Extended UV Exposure: Offers up to 1 year of UV exposure depending on the climate zone (180 days for Climate Zone 1, 270 days for Climate Zone 2, and 365 days for Climate Zone 3 and above). This provides greater flexibility during construction.
• Code Compliance & Certifications: ABAA evaluated, Building Code Evaluation ICC-ESR 2932 (AC38) compliant, NFPA 285 compliant, Red List Compliant (DECLARE), and has a Health Product Declaration (HPD 2.0) available.
• Reduced Glare: Its matte dark gray color minimizes glare during installation, enhancing worker comfort and safety.
  
  

DELTA®-VENT SA: Installation Made Easy

for Professionals

Proper installation is key to unlocking the full potential of any WRB. The DELTA®-VENT SA Installation Video provides a comprehensive step-by-step guide to ensure a flawless application, ideal for contractors and builders aiming for precision and efficiency.

Key Installation Highlights:

• Surface Preparation: Emphasizes removing protrusions and applying DELTA®-HF PRIMER or DELTA®-ADHESIVE (for cold weather) where needed to ensure optimal adhesion.
• Strategic Application: Can be installed vertically or horizontally, starting from the bottom of the building to ensure proper downward shingling for effective drainage.
• Window and Penetration Sealing: Detailed instructions on using DELTA®-FAS CORNER for rough openings, DELTA®-FLASHING for sills, and DELTA®-FLEXX-BAND and DELTA®-TILAXX or DELTA®-LFS sealants for penetrations to maintain airtightness and watertightness.
• Overlap Assurance: Demonstrates the secure 4-inch minimum overlap for side laps with the self-adhering edge, and taping end laps with DELTA®-MULTI-BAND tape for complete air barrier continuity.
• Final Inspection: Stresses the importance of inspecting for rips or tears and using DELTA®-MULTI-BAND or patches for repairs to maintain the system's integrity.
