Linear seam sealants

To comply with building regulations for fire safety, buildings must be divided into fire compartments. Fire resistance of the walls and ceilings between these fire separations can be rendered ineffective by seams, expansion joints and void spaces.

Walraven’s Pacifyre® and Tangit sealing products have been tested and approved for effectively fire stopping seams, joints and cracks between walls, floors and ceilings of fire compartments. They are also effective for sealing annular joints around (insulated) pipes, fire collars and sleeves. Our solutions prevent the spread of fire and smoke through joints in fire rated separations, and provide excellent adhesion to most substrates. An overview of our acrylic and silicone fire sealants can be seen below.

Tested for fire safety

Our products are tested by accredited European testing Institutes for their fire resistance in compliance with EN 1366-4 & EN 1366-3 and provide a fire resistance that is classified in accordance with EN 13501-2:2003 up to EI 240 inclusive. That is to say, 240 minutes of integrity and insulation, depending on material and configuration.

The Walraven Pacifyre Acrylic and Silicone Sealants are safe to use. The emission level is A+ and the Acrylic has achieved the highest possible EC1plus classification according the EMICODE® system. It also has a sound reduction performance of up to 62dB according EN ISO 717-1.
