Why Pyroblanket
Versatile and Tough
Sheds Splash
Thick silicone coating sheds molten metal and weld spatter.
Weatherproof
Impervious to water, oils, sunlight and corona – good outdoors and offshore.
Cut and Sew
Supplied in rolls or made into custom shapes.
Turns to Crust
Under long exposure the coating becomes a protective silica crust.
