The Wintermo membrane is a premium underfloor underlayment solution, engineered in Germany, providing superior protection for ceramic, porcelain, natural stone, vinyl, laminate, and other flooring installations. This specially formulated in-floor underlayment membrane is designed to prevent cracks in shower floor tile and grout. A standout feature of the Wintermo membrane is its cost-efficiency, making installation quick and easy, saving both time and effort.
It is recommended to use polymer-modified thin-set mortar adhesive for bonding porcelain and other challenging flooring tiles, as the membrane forms a strong bond with its reinforced fleece heat bond layer. No fasteners are required, further simplifying the installation process and saving time.
The Wintermo isolation membrane is both a waterproof and vapor-proof uncoupling membrane for tile, offering exceptional vapor barrier capabilities. This makes it ideal for crack prevention in various in-floor tiles, such as ceramic, porcelain, granite, marble, glass, mosaic, and natural stone tiles. It effectively absorbs stress from excessive substrate movement, preserving the surface and integrity of the ceramic floor tile.
Easy to install and compatible with various tile types, the Wintermo membrane offers superior protection and stability for your waterproof flooring projects. Whether for standard applications or challenging substrates, the in-floor Wintermo membrane ensures the longevity and performance of your tile installations. It is also suitable for renovating older kitchen tile flooring, basement flooring, bathroom floor tiles, and other living areas such as foyers, hallways, closed balconies, dining rooms, and bedrooms.
The Wintermo membrane is ideal for professional home improvement or DIY projects of any scope and is a great option for enhancing room decor, bathroom decor, kitchen decor, and overall home decor needs.
