Experience the ultimate in roofing underlayment protection and ease of installation with Epilay EpiStik SA-250. This premium, heavy-duty self-adhered synthetic underlayment is a superior alternative to traditional asphalt-based peel and stick products, featuring advanced engineering for reliable performance in demanding environments. The core of EpiStik SA-250 is its proprietary SBS Modified Bitumen based adhesive, providing excellent adhesion to both plywood and metal substrates across an impressive temperature range of -40°F to 260°F. Unlike asphalt alternatives, it will not dry out, crack, or leach oil in high heat, nor become stiff in colder temperatures, ensuring consistent performance and easy rollability.
The unique 3-layer facer features a deep embossing non-woven blue top surface, creating a high-traction GripWalk-like walking surface for enhanced safety on steep slopes, even in moist conditions. The 50 mil thickness provides robust protection, including effective Ice Dam Protection. Installation is further simplified by the unique 3″ Overlap Edge, ensuring excellent adhesion and a watertight seal at overlaps. EpiStik SA-250 is water repellent, non-absorbent, UV resistant for up to 180 days, and impervious to mold growth due to its 100% synthetic and polymer construction. It boasts a Class A Fire Rating (ASTM E 108), adding an extra layer of safety. This versatile underlayment is ideal for use under asphalt shingles, tiles (concrete and clay), shakes, and metal roofing systems. Crucially, Epilay EpiStik SA-250 is Florida Building Code and Miami Dade Approved, making it a trusted choice for projects in high-velocity hurricane zones requiring stringent impact resistance and sealing properties. It is a durable, strong, recyclable, and offers a Limited Lifetime limited warranty.
