Product Details:
- Manufacturer: ALCO Products, LLC
- Type: Self-adhering, high-temperature ice and water protector
- Application: Designed as a waterproofing underlayment for use with various roofing systems, especially those exposed to high temperatures.
Features:
- High-Temperature Resistance: Specifically formulated to withstand high-temperature environments, up to 240∘F (115∘C), making it ideal for use under metal, tile, and asphalt shingles in demanding conditions.
- Superior Waterproofing: Provides robust protection against water infiltration from ice dams, wind-driven rain, and pooling water, ensuring the integrity of the roof structure and building interior.
- Self-Adhering Membrane: Features a proprietary self-adhesive backing for easy, secure, and direct bonding to the roof substrate, allowing for efficient installation in a wide range of weather conditions (above 40∘F / 5∘C).
- Durable and Flexible: Constructed from a polymer-modified asphalt membrane, reinforced with a polyester fabric surface (or similar, depending on the specific HT variant) that provides a tough, skid-resistant, and UV-protected (for a limited time) underlayment.
- Self-Sealing: Seals around nails, staples, and screws, maintaining a watertight barrier and preventing leaks at fastener penetrations.
- Industry Compliant: Meets or exceeds industry standards, including ASTM D-1970 criteria, ensuring reliable performance for both residential and commercial applications.
- Ease of Installation: Features a split-release peel-off backing sheet and a top adhesive selvage-edge (in some versions) to ease alignment and enhance lap sealing. May be repositionable for accurate placement.
Applications:
- High-Temperature Roofing Systems: Excellent for use under standing seam metal roofing, metal shingles, metal roof panels, tile (clay and concrete), slate, and asphalt shingles where high heat is a concern.
- Critical Roof Areas: Provides a strong waterproof layer for valleys, eaves, ridges, dormers, skylights, and other flashing areas prone to water accumulation or ice dams.
- Versatile Use: Suitable for new construction projects and reroofing applications, offering enhanced protection in diverse climatic conditions.
Commercial and Residential: Appropriate for a wide range of building types requiring durable, high-temperature underlayment solutions.
