ZMesh carries an industry-leading 25-year manufacturer’s warranty. The long warranty is backed by the product’s construction: because ZMesh is installed under roofing or flooring rather than exposed to the elements, it is protected from UV damage, physical impact, and weathering. Heatizon’s distributors have documented ZMesh installations from decades ago that remain fully operational and visually unchanged. In most installations, ZMesh will outlast the roofing or flooring material installed above it.

The width choice affects heat output, not coverage area. The 9-inch mesh allows more runs to be placed in a given space, resulting in higher watts per square foot — up to 13 watts per square foot — making it the recommended choice for roof deicing where aggressive snow and ice melting is needed. The 12-inch mesh produces a lower watt density, which is better suited for radiant floor heating where even, gentle warmth is the goal. Heatizon’s design team specifies the appropriate width for each project based on application and local climate.

ZMesh serves two distinct applications: under-shingle roof deicing and ice dam prevention, and radiant floor and space heating. For roof applications, ZMesh is installed beneath non-conductive shingles, membranes, and wood decking to melt snow and ice from eaves and valleys. For floor applications, ZMesh is installed beneath virtually any non-conductive floor covering — including hardwood, tile, stone, carpet, engineered wood, linoleum, and vinyl — to provide even, comfortable radiant warmth. Both applications use the same physical element; the installation method and wattage configuration differ by use case.

ZMesh is a woven bright bronze metal mesh heating element manufactured by Heatizon Systems. It resembles screen door material in appearance and is approximately 1/16 inch thick, available in 9-inch and 12-inch widths and in lengths from 50 to 400 feet. The bronze construction is highly durable, fully recyclable, and designed to outlast the roofing or flooring installed above it. ZMesh has been in continuous production and use since 1979.
