What is Expanding Foam?

Expanding foam for insulation is a product made from a chemical reaction between isocyanate and polyol resin. Mixing these substances results in a substantial increase in size, expanding the foam up to 30-60 times its initial volume. This unique feature makes it ideal for specialised packaging, as it moulds to the contours of the item it's encasing. Additionally, it provides excellent thermal insulation and effectively prevents air infiltration.

Expanding foam, particularly in the form of spray foam insulation, has revolutionised the way we approach insulation in buildings. Its unique properties make it an ideal solution for a wide range of insulation needs, offering benefits that traditional insulation materials can't match.

How Expanding Foam works

Expanding foam works by expanding and hardening upon application, effectively filling gaps and voids with a durable, airtight barrier. This barrier not only insulates but also adds structural strength to the insulated area. It's a versatile material suitable for both new constructions and renovations of existing buildings.

Key Application Benefits

Energy Efficiency

One of the most significant benefits of expanding foam is its superior insulating properties. It effectively reduces heat loss, leading to lower energy bills and a more comfortable living environment.

Moisture Barrier 

Expanding foam creates a moisture-resistant barrier, protecting buildings from damp and mould, which are common problems in the UK's wet climate.

Soundproofing

In addition to thermal insulation, it provides excellent soundproofing, reducing noise transmission between rooms and from the outside.

Expanding Foam vs Traditional Insulation Materials

While traditional insulation materials like fiberglass and cellulose have their place, expanding foam offers several advantages. It's more effective in sealing gaps and cracks, provides better moisture resistance, and is easier to install in hard-to-reach areas.
