One part, rapid, moisture-curing expanding polyurethane foam which is gun applied and has excellent elasticity, air tightness and acoustic properties. Excellent adhesion to brick, block, stone, plaster and cementitious materials as well as wood, metal and a variety of plastics. The low post-expansion facilitates greater control during application.


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.

  • 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

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.

Safety data sheet must be read and understood before use. Extremely flammable - keep away from open flames and other ignition sources.

Delivery Information

As a full fixings merchant, we stock a huge range of products varying in size from minute to massive. In order to supply our products at such competitive prices and not overcharge where unnecessary, we have developed a shipping structure based on the size, weight and transportability of each product which will always offer the most cost effective shipping method.


All delivery charges are included and clearly displayed in the shopping cart (when using the shipping estimator) and also on the checkout page both before and during payment. All delivery charges are based on delivery to Mainland UK (excluding Northern Ireland, Isles of Man and Scottish Islands and Highlands).


We pride ourselves on quick and complete delivery services and we make every effort to ensure deliveries are always on time and exceed expectations. We will always endeavour to minimise any delays, however on some occasions there may be delays caused by manufacturers, suppliers or other factors which may be out of our control. It is important not to have tradesmen booked in or jobs ongoing that are reliant on the supply of the materials. Any deliveries that are outside of the timescales stated on the product page will be notified to you via email or phone and you will be kept in the picture at all times.
