Performance

Fire resistance tests have been conducted to BS476: Part 20: 1987 achieving 4 hours fire resistance in gaps up to 35mm wide. Tests were conducted between a number of substrates including Hardwood, Softwood, Steel, Concrete, Vermiculite Board and Aerated Concrete. Pyromas A shows good resistance to a wide range of commonly found chemicals. Care must be taken to avoid prolonged contact with hydrocarbon based products.

Application

Pyromas A is suitable as a permanent fire seal in low movement joints, door frame to wall gaps, dry lining and partitions.

Construction

Joints in structures should be dry, clean, and free of powder or dust.
Pyromas A should be inserted to the correct depth to ensure the necessary fire performance. To improve surface finish, smooth with a spatula. Cured Sealant can be over-painted.
