Versafire® is an A1 Non-Combustible board in accordance with BS EN 1716:2002 and 1182:2002 and is intended for use in both internal and external applications.

  • Fully External / Internal
  • Rot Proof
  • Impact Resistant
  • Acoustic Performance
  • Resistant To Attack From Vermin
  • Non-Toxic Under Fire
  • Can Be Nailed, Screwed, Stapled Or Bonded

Versafire® is suitable for a wide range of applications and is a major move forward in building board technology to meet increasingly stringent building regulations and demands for ever higher standards of durability, safety and economy.

Applications

When High Fire Resistance Is Needed in:

  • Metal / Steel Partitions
  • Timber Partitions
  • Suspended Ceilings
  • Spandrel Panel Partitions
  • Cold Bridging Systems

Standard panel size is 2400mm x 1200mm although Versafire® is available in 1830 x 915 for the application of fire door blanks.

Freeze/Thaw Test
Frozen at -17.5°c + 2.5°c continuously for over 16 hours. Kept frozen at -17.5°c for 4 hours. Thawed by immersing in water at approximately 20. Maintained at a temperature of 20°c ± 3°c for 5 hours. Freeze and thaw cycle is repeated 10 times.

Test result: No cracking, disintegration, crumbling, stripping occurs on the Board and it achieves the Freeze/thaw value of 1.97%

Water Endurance Test
No bloating on reverse side. Non-occurrence of swelling, breakage nor tearing apart of the board.

Compressive Strength

Conditioning: Unless otherwise specified, all test specimens were conditioned at 23 + 2°C, 70 + 15% relative humidity and tested at 23 + 2°C, 50 + 5% relative humidity.
