Applications

• As part of the comprehensive Firepro range of fire protection products, Softseal incorporates a product specifically designed to form a linear joint seal within buildings, where the design needs to accommodate movement in the joint
• It may be installed horizontally or vertically and is suitable for linear joint widths up to 200mm
• Can also be used as a ‘head-of-wall’ barrier to extend the fire resistance and acoustic performances of masonry walls that finish at suspended ceiling height, up to the concrete soffit above
• Can be used in conjunction with Rockwool Ablative Coated Batt for head-of-wall applications.
• Comprises a low-density stone wool Firepro SoftSeal batt, pre-coated with Firepro SoftSeal Flexible Coating
• Depending on the application, strips can be supplied on either one or both sides. (Single Sided for Horizontal Applications. Double sided for Vertical Applications)
• Supplied in strips 1200mm x 200mm x 100mm

Performance

Fire performance

• Tested to the dedicated fire resistance standard for linear joint seals BS EN1366-4 and shown to provide up to 4 hours* fire performance (E240 & EI80)
• Certified by UL and CE marked to EAD 350141-00-1106

*Subject to application.

Movement

As part of the testing to BS EN 1366-4, Firepro SoftSeal was assessed for its movement capabilities, prior to conducting the
fire test. The product was tested to accommodate movement (expansion and contraction) of +/-25%.

Acoustics

Tested to EN 10140 based on two thicknesses with the following results:

• Rw 30 dB: When installed with 100mm thick SoftSeal Batt
• Rw 39 dB: When installed with 200mm thick SoftSeal Batt
• Dn,e,w 40 dB: When installed with 100mm thick SoftSeal Batt
• Dn,e,w 49 dB: When installed with 200mm thick SoftSeal Batt

Water Permeability

Tested to EN 1027 - No leakage observed up to 300Pa.

Air Permeability

• Tested to EN 1026 up to 600Pa
• Leakage at 50Pa - 0.1/1.4 m³/m²/h

Installation

• Please see Product Data Sheet and Installation Guide for detailed installation instructions.
• Measure the width of the Linear Joint to be sealed
• Cut the strips up to 25% bigger than the joint width, so when installed they are under compression
• Ensure substrate is clean and free of dust and debris
• Install the strip with the coating on the top surface
• Apply Firepro SoftSeal Flexible Coating to the face of all joints between the seal and the substrate, overlapping by 20mm
• Apply Firepro SoftSeal Flexible Coating to the faces of all butt joints between pieces of Soft Seal Linear Joint Seal
