Everbuild Sika Pyro Mate Firesil White Fire-Rated Silicone Sealant

The Everbuild Sika Pyro Mate Firesil is a premium neutral cure, elastic silicone sealant that complies with EN1366-4 standard for fire retardancy, making it an essential product for fire safety applications in buildings.

With a fire rating of up to 4 hours in specific joint configurations, this sealant is CE marked under both ETAG 026 Part 3 and EN15651-1:2012 type F-EXT-INT CC class F 25LM, ensuring high performance and reliability. It is suitable for sealing building joints, voids, and irregular holes in fire walls, partitions, and other structures requiring fire resistance.

This white silicone sealant adheres well to most surfaces, including porous and non-porous substrates, while maintaining permanent flexibility. It also offers excellent weathering properties, making it suitable for both internal and external use.

Ideal for joints up to 50mm wide and 25mm deep, though a primer is recommended for most construction substrates for optimal adhesion.
