HB42 Ultimate LXP Low Expansion Foam

HB42 Ultimate LXP Foam is an ultra-low expansion spray foam, perfect for fixing window and door frames, insulating cavities, cracks, gaps and surroundings of pipework (hot or cold), cables and ducting. Its superior adhesion allows it to be used on concrete, brick, stone, wood, plaster, metal, plastics and more.

Ultra Low Expansion means it doesn’t rise or expand as much as the other foam products, making it less permeable to air and moisture and therefore supremely strong.

HB42 LXP Foam is not only ultra-low expansion but also features a Unique Start / Stop Valve that stops it from curing in the can, so you can pick it up and use again – and most importantly, waste less! *Note that the straw must still be cleaned out each time.
