Closed Cell

Closed cell spray and injection foam insulation

Closed Cell foam insulation is designed for external walls, floors, roofs and soffits and provides a seamless airtight insulation solution. This type of foam can also be used for cavity wall insulation and stabilisation as well as insulation and weatherproofing of roofs externally.

As it says on the tin, these cells inside a closed cell foam remain closed, meaning that there are no gaps for the air to fill. So, our closed cell foam creates an airtight barrier so air isn’t able to pass through the foam.

Closed cell spray foam will definitely make a significant contribution to a comfortable indoor environment for whoever is inside the insulated building, by creating a draft-free climate and reducing the overall rate of heat loss from a building, thus saving you money on utility bills for your building/warehouse.

On top of all that the cell structure of closed cell foam only permits low levels of water vapour to pass through meaning that this spray also helps control the movement of moisture throughout your building thus reducing the risk of condensation and mould. Also, this type of foam helps over time it can even prolong the buildings life as closed cell foam has a much higher density than open cells and is a more solid inside a structure as it can protect your building against premature deterioration.

  • Joints
