SkamoSteel S-Isol WR is a lightweight insulating board with excellent insulation value, high mechanical strength and good heat resistance. The boards are designed for maximum temperatures of 1,100°C (2,012°F) and are applicable as back up insulating lining. SkamoSteel S-Isol WR is delivered with a water repellent surface treatment on one side. Water repellence is achieved by application of a coat of potassium siliconate identified by a light blue colour.

Due to its high resistance to carbon monoxide and hydrocarbons, SkamoSteel S-Isol WR can be used in furnaces with reducing atmospheres. No disintegration of carbon deposition is found after 200 hours' exposure to CO at 450°C (842°F).
