FIREPRO® SoftSeal Linear Joint Seal is designed to fire stop linear joint seals in buildings where movement is a factor in the design.

FIREPRO® SoftSeal Linear Joint Seal comprises medium density, lamella stone wool insulation, SoftSeal batt, pre-coated with SoftSeal Flexible Coating. It is designed for installation horizontally or vertically and can be applied to linear joint widths up to 300mm§. Where masonry walls finish below a suspended ceiling height there is significant risk of spread of flames and smoke, in addition to noise travelling between rooms day to day. FIREPRO® SoftSeal Linear Joint Seal can be used as a ‘head-of-wall’ barrier to extend the fire safety protection and acoustic performance properties of the walls. 

FIREPRO® SoftSeal Linear Joint Seal has been tested to BS EN1366-4 and has been proven to provide up to 4 hours’ fire performance (E240 & EI180). It has also been assessed for its movement capabilities, tested to accommodate movement, expansion and contraction, of +/- 25%.
