Overview of One-Component PU Spray Foam


LOTFIX F32 One-Component PU Spray Foam is a closed-cell spray polyurethane foam developed for thermal insulation and sound insulation in building applications. Applied with an applicator gun and nozzle, it creates a seamless insulation layer that helps cover surfaces more completely without the joints and gaps often found in traditional insulation materials.

This product is suitable for roofs, attics, walls, floors, basements, ceilings, pipes, tanks, and other uneven or hard-to-reach surfaces. Its sprayable format makes it especially practical where shaped surfaces, corners, or irregular building areas are difficult to insulate with boards or rock wool.

Why Spray Foam Matters

Seamless Insulation Layer

Spray application helps form a continuous insulation layer without the cut joints and connection gaps common in board-type insulation.

Better for Difficult Surfaces

It is easier to apply on uneven, rough, curved, or hard-to-reach surfaces where traditional insulation materials are less practical.

Built for Insulation Work

F32 is positioned around insulation performance first, making it more suitable for spray insulation applications than standard filling-focused PU foams.

Recommended Areas of Use

Roofs and Attics

Suitable for spray insulation in roof structures, attic areas, and upper building spaces.

Walls, Ceilings, and Floors

A practical option for interior walls, ceilings, floors, partitions, and other enclosed areas.

Pipes, Tanks, and Round Surfaces

Useful for insulating pipes, canals, tanks, and other curved or circular surfaces.

Vehicles and Marine Use

Can be used in car bodies, trailers, boats, yachts, and other vehicle insulation applications.
