Fire Rated Sealant- Intumescent, Acrylic and Acoustic Mastic
Fire Rated Intumescent, Acrylic & Acoustic Mastic Sealant in white – 310ml cartridges (Boxed in 12’s)
Fire rated sealant tested to BS 476: Part 20 & 22 and tested to BSEN ISO 140/3. Achieved 55 DB RW for sealing linear gap seals and small floor/wall penetrations.
What does a fire resistant sealant do?
The FR Acrylic is a halogen-free, polymer emulsion based sealant that swells when subjected to temperatures in excess of 125 C and forms a char coat that restricts the passage of smoke and fire. The mastic seal is easily applied and dries to leave a smooth, flexible surface, perfect for painting over. The mastic sealant has excellent adhesion to a wide range of substrates and will not harden or crack with age.
What is mastic sealant used for?
The fire rated mastic forms a fire and smoke seal in joints up to 35mm wide without slumping. Mastic is ideal for sealing joints in and around internal partitions, lap joints in fire-rated cladding and for sealing between walls, floor, fire doors and fire-rated walls. It is recommended that a sealant depth of at least 15mm be applied.
If the fire sealant is to be overpainted, building regulations may require a fire-resistant coating.
SPECIFICATION COMPLIANCE
The FR acrylic has been independently tested to the following assessments:
-BS EN 1366-3: 2004 & BS EN 1366-4: 2006 Tested at Bodycote WarringtonFire,
achieving 4 hour integrity and insulation rating for a range of linear and penetration seals.
-an indicative fire test based on BS476 Part 20 at Warrington Fire Research and
achieved 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 acoustic tested Measurement of Airborne Sound Insulation of Building
elements.
University of Salford reports 125-76;77 and 79. The sealant maintained the integrity of a plasterboard partition wall with a Sound Reduction Index of 55dB
Intumescent sealants are designed to upgrade fire protection and resistance of a fire door. These sealants are needed to fill small and hard to access gaps which need to be sealed.
Intumescent sealants are designed to provide passive fire protection and resistance when exposed to extreme heat but they not all intumescent sealants reduce sound transmission, only a select few do.
The lifespan of fire mastics without exposure to extreme temperatures can last up to 8 -10 years. Most high quality fire rated mastic sealants have strong durability even when exposed to extreme heat, and toxic fumes but will still degrade over time due to exposure.
Fire mastics can shrink which is normal and nothing to worry about because the fire mastics have minimal shrinkage to maintain fire resistance and sealing properties.
