Description
A one part fire rated intumescent acrylic mastic designed for sealing gaps around fire doors, window frames and for sealing joints, voids and irregular holes in fire rated structures, and for maintaining their integrity when sealing around pipes and cables that penetrate them.
The mastic has been independently tested in accordance with BS476: Part 20 & 22: 1987 and can provide up to 4 hours fire resistance depending on depth/width and volumetric area.
Can be used on most construction substances, although we do recommend that a small area is tested on unusual substrates. It can be used in most low movement joints up to 25mm wide with no slump and can be overpainted. Further details and installation instructions available on request.
Acoustic performance: Weighted Sound Reduction Index (RW) of up to 57db to BSEN ISO 140-3.
