The Chemelex NUHEAT NUMEM250PS Peel & Stick Membrane Sheet (FG0800_1) is a tile underlayment and uncoupling system specifically engineered to integrate seamlessly with nVent NuHeat electric floor heating cables. It offers outstanding uncoupling and waterproofing properties, helping to prevent tile cracking and substrate movement. When installed in combination with nVent NuHeat heating cables and a thermostat, it creates a reliable, energy-efficient radiant floor heating solution. The system provides soothing heat to tile and stone floors. It is energy-efficient and easy to install. Chemflex NuHeat floor mat is a flooring underlayment that can be installed over the entire subfloor for uncoupling, crack isolation (crack in the floor prevention), and waterproofing purposes.
Unlike the standard Chemflex NuHeat membrane sheet, the Peel & Stick version features a factory-applied pressure-sensitive adhesive backing protected by a release liner, eliminating the need for thin-set mortar beneath the membrane. This innovative design reduces floor buildup, speeds installation, and creates a strong, lasting bond to properly primed substrates. Integrated mortar vents cut into the top of each square-shaped column allow thin-set mortar applied above to flow through and bond directly to the substrate below, ensuring a permanent, secure tile installation with even floor heat distribution.
The Chemflex NuHeat Peel & Stick Membrane eliminates the need for a second layer of plywood or cement backer board in most tile installations, thereby reducing floor buildup. It is designed for the quick and easy installation of nVent NuHeat electric heating cables, now part of the rebranded Chemflex Heating System. Chemelex NuHeat mat serves as a flexible layer between the subfloor and your flooring assembly, providing a stable base that is bonded to the subfloor with the factory-applied adhesive after priming the surface. This infloor uncoupling layer is effective in neutralizing tension, delamination, and lateral stress from transferring to tile covering surfaces, ensuring long-term structural integrity over tiled subfloors.
Suitable for various floor tiles, 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, concrete blocks, engineered stone tiles, or natural stone tiles installed directly on top of it. Also suitable for linoleum tile applications, carpet tile, vinyl flooring, and stone flooring, the Chemflex NuHeat Peel & Stick Membrane provides a reliable foundation. Designed for use with underfloor heating systems and underfloor temperature regulation, this underlayment supports a comfortable, energy-efficient, and long-lasting floor system.
The Chemflex NuHeat uncoupling and waterproofing membrane achieves a 'high-performance' rating under the ANSI A118.12 standard for system crack resistance test and 'Extra Heavy' rating in the Robinson Floor Test (ASTM C627), indicating its capability to withstand high-traffic environments. This makes it ideal for commercial spaces such as hotels, restaurants, retail stores, office buildings, shopping malls, healthcare facilities, and industrial kitchens, providing long-lasting protection and superior waterproofing in commercial and industrial settings, ensuring a strong and durable flooring system for years to come. It is rated for a maximum ambient temperature of 194°F (90°C). The Chemflex NuHeat Peel & Stick membrane (nVent NuHeat underfloor mat) is available in a convenient 10.6 sq ft size, making it ideal for both professional installations and DIY home improvement projects of any scale.
The Chemelex NuHeat membrane underlayment is an excellent option for your remodeling and home renovation needs and enhances room décor, bathroom décor, kitchen décor, and overall home décor. It's a robust tile underlayment membrane (heated floor mats) that makes it usable in your shower, bathroom, hot tub and bathtub surround, kitchen, laundry room, steam room, basement, entryway, hallway, dining room, and other wet areas where potential water leaks (water damage) are a concern. Perfect for bathroom tile, kitchen tile, and shower tile installations, it helps ensure reliable, long-lasting performance in moisture-prone areas.
The Chemelex NuHeat heating system allows you to create a bathroom heated floor and a warm, inviting space in your living room. The membrane's design facilitates easy on-site adjustments, accommodating complex floorplans with curves and angles. The NUHEAT FG0800_1 Peel & Stick membrane sheet is 1/4 inch thick, minimizing the finished floor height, while its durable and flexible design reduces installation time, providing a seamless, professional finish.
The Chemflex NuHeat uncoupling membrane also acts as a crack prevention barrier that preserves the surface and integrity of the tile and grout. It also functions as a vapor management solution in ceramic tile and stone installations and absorbs shear stress from subfloor movement, and prevents damage to your floor tile or grout.
The polypropylene plastic layer features square-shaped columns with integrated mortar vents that form channels specifically designed to embed and securely hold the nVent NuHeat Cable in place, allowing precise temperature regulation of your tiled floors through the Chemflex thermostat.
The shape of the Chemflex NuHeat Peel & Stick Membrane also functions as a vapor management system that allows moisture to escape from the substrate during the curing process. The polypropylene layer is heat-welded to a pressure-sensitive adhesive base for quick application to primed surfaces. Compatible subfloors include concrete, plywood, OSB, wood, concrete backer board, gypsum underlayments, and other approved substrates.
