Product Description

The ROCKWOOL FIREPRO® range is comprehensively designed for fire protection and fire stopping products. FIREPRO® SoftSeal Linear Joint Seal is made up of products specifically designed to create linear joint seals in buildings where movement is a factor in the design.

FIREPRO® SoftSeal Linear Joint Seal comprises low density stone wool mineral 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 resistance 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 & EI80). It has also been assessed for its movement capabilities, tested to accommodate movement, expansion and contraction, of +/- 25%.
