Fyrewrap marine blanket from Unifrax is a totally inorganic, flexible, high temperature insulation blanket specifically designed to provide passive fire protection for marine applications. The calcium, magnesium, silicate chemistry is designed to enhance bio solubility.

Unifrax’s proprietary fibre spinning technology combined with mechanical needling of the fibres eliminates the need for binders in the product. This results in a material with high tensile strength and superior thermal and acoustical properties. Fyrewrap marine blanket is chemically stable and it's thermal properties are unaffected after exposure to water immersion or high humidity.
