nVent RAYCHEM WinterGard Mat/Mesh are constant output heating mats for fast and effective ramp and access way heating, to prevent snow and ice formation. Pre-defined power and pre-terminated, available in varying fixed lengths for installation on concrete, screed and asphalt.

The heating mat should be installed on a stable subsurface. In suspended structures the substratum may consist of finished slabs, pre-stressed concrete or a suspended structure with poured concrete. The heating mat can be laid on all sub surfaces. In the case of poured concrete, it should be ensured that the surface is smooth and all sharp objects are removed. Ramps on a solid substratum do not require any additional thermal insulation. Appropriate preparations should be made for installing the temperature and moisture sensor. Recommended split/gravel sizes for sand bed or cement concrete: Round grain gravel: 8-16 mm Grit/Broken grain: 4-8 mm
