Product Description:

The Profilitec Floortec Uncoupling Membrane Roll is a premium-grade crack isolation solution engineered for superior floor protection and tile longevity. Designed with advanced Lay-Flat Technology, this anti-fracture membrane eliminates edge curling during installation, saving time and effort for professionals and DIY users alike. Manufactured from high-density virgin polyethylene, the underlayment delivers exceptional load-bearing strength and resistance to structural movement. Its translucent composition allows for easy verification of thin-set mortar coverage, minimizing installation errors and voids beneath tile surfaces. The innovative circular column structure enhances mechanical bonding between mortar, membrane, and tile, ensuring optimal adhesion and load distribution.

This 1/8-inch thick membrane is ideal for a wide range of applications, including residential, commercial, and light industrial flooring installations. It compensates for lateral shear movement and differential expansion between the tile and substrate, such as concrete, gypsum, wood, OSB, drywall, cement board, hydronic slabs, or plywood. The Profilitec Floortec membrane meets ASTM C627 Extra-Heavy Commercial standards and serves as a reliable uncoupling, waterproofing, and vapor management solution in moisture-prone environments like bathrooms, balconies, showers, kitchens, laundry rooms, and basements. Suitable for indoor and outdoor use, it provides outstanding performance in tile installations over radiant floor heating systems, cracked substrates, or in areas subject to frequent temperature fluctuation.

Compatible with a variety of tile finishes, including ceramic, porcelain, cement, granite, marble, travertine, natural stone, mosaic, and glass tile, this uncoupling underlayment ensures durability and stability in wet areas and dry areas alike. It also contributes to acoustic insulation by reducing sound transmission through floors in multi-story homes and commercial buildings. Measuring 3.3 ft x 98.4 ft (323 sq ft total), the roll can be quickly trimmed and applied using a standard utility knife and thin-set mortar. Whether you're working on a large flooring renovation or a small tiling project, Profilitec Floortec membrane offers a lightweight, easy-to-handle, cost-effective solution for floor crack isolation and tile support with long-term reliability.
