About: We are a company that specialise in the applicatio­n of high quality polyuretha­ne spray foams for residentia­l, commercial and marine insulation­.
Services offered: NZAS offer closed & open cell spray foam insulation, as well as injection foams in a range of densities to suit your needs.
Areas serviced: Based in Auckland, with mobile spray units to service the upper North Island.
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 .78 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 closed 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.

Shipping containers conversions are becoming popular for dwelling spaces. The issue with using shipping containers as a dwelling is that they develop condensation against the steel which can cause mould and rust.

Polyurethane spray foam offers a solution to the issue of condensation and corrosion by providing an air tight barrier between the steel and the wall cavity. This creates a drier and warmer container-home than would otherwise not be possible with conventional insulation materials, which allow water vapour to condense on the steel.If conventional insulation such as polystyrene panels or fibreglass is used the still allow the warm moist air inside the container to find it way to the outer steel and condense.
