FM330 is ideal for use as an air tight gap filler for general construction joints including where movement is expected to occur. It is suitable for applications such as airtight window and door perimeter joint seals, sealing floor to wall and wall to ceiling joints and pipe & service penetrations.

FM330 is not UV resistant and should be protected from sunlight with a suitable opaque sealant, filler or paint. As with all PU foams, it does not bond to polythene, Teflon®, siliconised or wax-like surfaces.

  • A high performance PU foam with excellent acoustic and airtight performance.
  • Airtight formulation - tested to EN 12114.
  • Acoustic dampening - up to 63 dB joint insulation index.
  • Elastic performance - up to 50% movement capability ensures integrity of the seal in the event of movement.
  • Sub-zero formulation - can still be used at temperatures as low as -3°C.
  • Low post-expansion facilitates more accurate application depth.

Safety data sheet must be read and understood before use.
