BS EN 1366-3: 2004 & BS EN 1366-4: 2006 achieving 4 hour integrity and insulation rating for a range of linear and penetration seals.
An indicative fire test based on BS476 Part 20 achieving a 4 hour fire rating (integrity) for a range of vertical and horizontal joints up to 35mm wide between various non-combustible construction materials. A 1 hour fire rating (integrity) was achieved for a range of vertical joints up to 25mm wide between combustible materials (timber).
BS EN ISO 140-3. 1995 Measurement of Airborne Sound Insulation of Building elements. The sealant maintained the integrity of a plasterboard partition wall with a Sound Reduction Index of 55dB.
FIRESHIELD AC is specially manufactured to form an acoustic and fire rated intumescent barrier in construction applications.
When subjected to heat Bond It FIRESHIELD AC swells (intumesces) to provide an inert barrier to smoke and flame.
The fire resistance achievable with Bond It FIRESHIELD AC depends upon the joint design, depth of sealant and substrates being sealed.
It is non-slumping and rapid skinning. It can also be overpainted within 1 hour with fire resistant paint.
