Overview
About ProRox® WM 971
ProRox WM 971 is a lightly bonded heavy-duty stone wool insulation mat stitched on galvanized wire mesh with galvanized wire. The wired mats are produced with an innovative water-repellent binder, known as WR-Tech™, to mitigate the risk of corrosion under insulation (CUI). WR-Tech ensures our stone wool maintains its superior water repellency even at elevated operating temperatures within the CUI range, while preserving its excellent thermal performance in use.
Application: The wired mat is suitable for the thermal and acoustic insulation of industrial installations subjected to vibrations and exposed to the environment, such as outdoor industrial pipework, reactors and furnaces.
Key benefits
- Suitable for heavy duty applications which are exposed to high temperatures and high mechanical loads
- Resistant to high temperatures
- Flexible application
- Available in a wide range of thicknesses
- Suitable for use over stainless steel
