Expanding Foams

Expanding foam, also known as insulation foam, is a product that provides airtight insulation around materials, joints and components. The foam acts as a filler to seal cracks and holes around parts and fittings. These sealants form a barrier to repel moisture, insects and air from creeping into gaps.

Expanding foam normally has a mousse-like consistency, which hardens via a chemical process when it comes in contact with atmospheric humidity. Once cured or hardened, the foam will not expand or shrink, being durable against damp and other weather effects.

What is expanding foam used for?

Expanding foams have many uses across industry and retail. The foam sealant can be used to fill the openings and insulate around window frames, window sills and awkward gaps, and to seal pipes and hoses.

Expanding foams are also applied in indoor building activities and in repair work to ceilings, walls and cavities. The foams are rot-resistant and can be used to bond and seal the rings around manholes.

How to use expanding foam?

A foam gun or a nozzle applicator can be used for the application. Spray foam directly into the required area, as the PU foam needs moisture to expand and cure it is advised that if applying in a dry area the user lightly mists with water first. Once cured any excess can be cut or sanded off or additional foam can be added.

Expanding foam comes in different variants, usually in an aerosol can, customised to the task they need to be used for, whether filling, coating or barricading.
