Designed for radiant heated floors, tile protection, waterproofing, and crack isolation, this membrane helps create a durable and energy-efficient floor assembly for residential, commercial, and high-traffic applications. When installed with compatible Nuheat heating cables and a thermostat, it supports reliable floor temperature control and consistent warmth across tile and stone surfaces. Compatible with top-tier mortars, including Mapei Keraflex RS, Schluter ALL-SET, LATICRETE 254 Platinum, Custom Building Products VersaBond-LFT, TEC Full Flex, ARDEX X 5, and ARDEX X 77. Ensure ANSI A118.11 compliance when installing over plywood or OSB. Suitable for DIY and professional installation, accommodating straight, curved, or angled floor layouts across varied room shapes and floor plans.\u003c\/p\u003e\n\u003cp\u003eThis updated Nuheat Membrane design offers greater load-bearing capacity, improved shear strength, reduced roll memory, increased thermal mass within the subfloor assembly, and enhanced vapor management performance. These improvements help make installation easier while supporting long-term tile stability, improved mortar bonding, and dependable radiant heat transfer. The new pillar cavity shape is designed to help eliminate pieces of hardened mortar from releasing during installation, creating a cleaner, more secure surface for placing Nuheat electric heating cables. Its reduced roll memory also supports easier handling, faster layout, and improved flatness during installation. The Chemelex Nuheat Membrane eliminates the need for a second layer of plywood or cement backer board in most approved tile installations, reducing finished floor buildup and saving installation time. Its 1\/4\" low-profile design helps maintain a minimal floor height while still delivering strong uncoupling, waterproofing, crack isolation, and radiant floor heating performance. The membrane is ideal for remodeling, renovation, bathroom heated floor projects, kitchen tile installations, shower tile applications, and professional flooring upgrades.\u003c\/p\u003e\n\u003cp\u003eChemelex Nuheat Membrane serves as a flexible uncoupling layer between the subfloor and the finished flooring assembly. It is bonded to the substrate with thin-set mortar adhesive, creating a stable base that helps absorb substrate movement and reduce stress transfer to the tile covering. This infloor uncoupling layer helps neutralize tension, lateral movement, delamination risk, and shear stress, helping prevent cracks in tile and grout while supporting the long-term structural integrity of the flooring system. This flooring underlayment for tile is suitable for many approved tile and stone coverings, including ceramic tile, porcelain tile, vinyl tile, cement tile, granite tile, marble tile, travertine tile, slate tile, limestone tile, sandstone tile, onyx tile, quartzite tile, mosaic tile, glass tile, engineered stone tile, and natural stone tile. It can also support select approved flooring applications such as linoleum tile, carpet tile, vinyl flooring, and stone flooring when installed according to manufacturer requirements. Designed for use with underfloor heating systems and underfloor temperature regulation, the membrane helps create a comfortable, energy-efficient, and long-lasting heated floor system.\u003c\/p\u003e\n\u003cp\u003eThe Chemelex Nuheat uncoupling and waterproofing membrane achieves a high-performance rating under ANSI A118.12 for system crack resistance and an Extra Heavy rating in the Robinson Floor Test, ASTM C627. This makes it suitable for demanding commercial environments such as hotels, restaurants, retail stores, office buildings, shopping malls, healthcare facilities, and industrial kitchens. Its durability, greater load-bearing capacity, and enhanced shear strength help support long-lasting protection in high-traffic flooring installations. The Chemelex Nuheat Membrane is also an excellent option for wet areas and moisture-prone spaces, including showers, bathrooms, bathtub surrounds, kitchens, laundry rooms, steam rooms, basements, entryways, hallways, dining rooms, and other interior areas where water exposure or water damage may be a concern. Its waterproofing and vapor management properties help protect the floor assembly while allowing moisture within the substrate to escape during curing, supporting better mortar performance and long-term adhesion.\u003c\/p\u003e\n\u003cp\u003eThe membrane’s polypropylene plastic layer features square-shaped columns that form channels designed to embed and securely hold nVent Nuheat Cable in place. This design allows precise cable spacing, stable cable placement, and accurate temperature regulation through a compatible Chemelex or Nuheat thermostat. The improved pillar cavity shape helps prevent hardened mortar pieces from releasing during installation, making the membrane easier to work with while supporting a cleaner and more reliable heating cable layout. The polypropylene layer is heat-welded to a non-woven polypropylene fabric that absorbs thin-set mortar and creates a strong bond to the subfloor. Ensure ANSI A118.11 compliance when installing over plywood or OSB. Suitable for DIY and professional installation, accommodating straight, curved, or angled floor layouts across varied room shapes and floor plans. With its low-profile design, enhanced vapor management, improved thermal mass, strong uncoupling performance, and reliable compatibility with Nuheat electric heating cables, the Chemelex Nuheat Membrane provides a professional foundation for durable, comfortable, and efficient heated tile floors.\u003c\/p\u003e","brand":"Nuheat","offers":[{"title":"Default Title","offer_id":48792777654489,"sku":"NUMEM_NEW_161","price":507.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0641\/4676\/8089\/files\/1-2026-06-09T103525.618.jpg?v=1781015769","url":"https:\/\/gtdsupply.com\/products\/nvent-nuheat-2000005808-uncoupling-heating-membrane-161-sq-ft-roll-non-woven-polypropylene-heating-pad-anti-fracture-floor-underlayment","provider":"Global Trade \u0026 Distribution Inc.","version":"1.0","type":"link"}
