Spray foam

Polyurethane Spray Foam is the solution for all your insulation needs. It is a seamless, “spray-in-place” insulation that is low density, rigid, closed-cell,  foam. It has the most efficient insulating properties available.

It comprises of a 90% closed cell formation, thus drastically reducing the chances of water absorption or transmission. Polyurethane has tremendous  thermal properties. Our closed cell foam has an R value of 1.23 per 25mm making it the most efficient insulation for residential housing . We prefer to use only closed-cell foam as it has the highest R-value, lowest perm rating for water vapor transmission, and adds structural integrity as well as soundproofing. Not all spray foams provide these benefits.

We can also offer open cell foam which has a R value of .6 per 25mm.

Open cell Foam has a lower density than Closed cell foam and requires a thicker application to achieve the equivalent "R Value". The cost works out at approximately the same price as closed cell for a given "R Value" . It has a better noise insulation properties than open cell foam. Open cell foam will insulate and air seal but will allow water vapour to migrate through it. Please contact us to discuss your insulation requirements and select the appropriate foam for your application.

At NZAS We offer a complete range of Polyurethane foams.

  • Low density open cell foams used in household insulation.
  • Closed cell foams used in Domestic and Industrial envorinments.
  • Higher density foams for structural strength.
