Managing extreme heat and preventing moisture intrusion are two of the toughest challenges facing modern roofing contractors. TECH WRAP HT SBS Self-Adhered Underlayment, manufactured by Tech Wrap, LLC, offers an advanced solution designed specifically to withstand severe environmental stress on high-end steep-slope assemblies.
This 40-mil membrane is composed of a proprietary elastomeric styrene-butadiene-styrene (SBS) polymer-modified bitumen blend paired with an aggressive, high-tack self-adhesive backing. The topside is surfaced with a heavy-duty tri-laminate woven polyethylene film that stands up to heavy foot traffic and elements. Crucially for modern designs, TECH WRAP HT is rated for service temperatures up to 260°F, ensuring it will not degrade or run under dark metal roofing systems or intense summer sun.
Contractor speed and safety are central to its design. The underlayment features an easy-to-remove silicone release film that peels away smoothly at an angle for a rapid, wrinkle-free layout. With a 100% UV-protected top film, the dry-in can safely remain exposed to sunlight for up to 90 days, offering ultimate scheduling flexibility on multi-phased jobs. Backed by rigorous testing and major structural code approvals, TECH WRAP HT SBS from A1A Wholesale Supply provides the peace of mind and commercial reliability your premium roofing projects demand.
Key Features and Benefits for Contractors:
- High-Temperature Performance: Designed to safely withstand extreme service temperatures up to 260°F (126°C) without degradation.
- Proprietary SBS Formulation: Made with high-quality elastomeric styrene-butadiene-styrene modified bitumen for superior flexibility and self-sealing capability.
- Tri-Laminate Top Film: Surfaced with a high-strength tri-laminate woven polyethylene film for rugged durability and puncture resistance.
- Aggressive High-Tack Adhesive: Powerful self-adhering backside creates an immediate, secure bond to approved roof substrates.
- 90-Day UV Exposure: Features 100% UV protection, allowing the dry-in to remain exposed for up to 90 days before final cladding installation.
- Fast Installation: Backed with a split silicone release film that removes quickly and cleanly at an angle to save labor time.
- Excellent Cold Flexibility: Maintains performance and flexibility down to low temperatures of -20°F (-29°C).
- Code Approved Protection: Fully classified by UL and carries prestigious Florida Building Code and Miami-Dade County approvals.
Basic Uses:
- High-temperature underlayment protection for steep-slope architectural and structural metal roofing systems.
- Premium water and ice protection under high-end asphalt shingle roofing assemblies.
- Comprehensive full-deck waterproofing for valleys, eaves, rakes, ridges, and low-slope transitions.
Installation Considerations & Limitations:
- Temperature Ranges: Ambient and surface temperatures must be between 40°F (4°C) and 110°F (43°C) during application.
- Substrate Conditions: Do not attempt installation if ice, snow, moisture, or dew are present on the roof deck.
- Dew Point Rule: Ensure ambient roof temperatures are a minimum of 5 degrees above the local dew point before applying.
- Application Best Practice: Unroll the membrane onto the roof surface and allow it to relax before positioning. Once placed, remove the silicone backing and roll the membrane firmly with a weighted roller to ensure total, positive adhesion.
- Storage Requirements: Store rolls strictly in an upright position to prevent flattening or damage; do not double-stack pallets. Maintain clean, dry storage conditions between 55°F (12.8°C) and 80°F (26.7°C).
- Shelf Life: Approximate shelf life is 12 months from the date of manufacture when properly stored indoors.
