Ncell8 500

Ncell8 500 is a castor based water based open cell breathable soft spray foam insulation. It is designed specifically for use in domestic structures.

Ncell8 500 is an open-cell spray foam. It is extremely economical and can hugely reduce the amount of unmanaged moisture and air infiltration.

Ncell8 500 is applied using a spray gun. It is applied as a liquid and within seconds, it expands to 150 times its liquid volume. The foam is sprayed directly onto the substrate which forms a permanent seal over the most difficult shapes in a seamless fashion.

This seal increases energy efficiency and really improves the quality of air indoors by eliminating the movement of air through walls.  The performance of Ncell8 500 will be consistent throughout the lifetime of the building.

In order to meet building regulations, Ncell8 500 has been put through extensive testing to ensure its non-toxic nature. It has been developed with the environment in mind and as a result, no toxins are emitted after installation.
