Spray Foam overview

Spray foam insulation is mixture of two liquid chemical components under heat and pressure in a spray gun.

When the two components are mixed and sprayed as a liquid they react to produce a foam which expands and sets within seconds, sticking to and sealing against the substrate.

Foams are classified by their density (high, medium or low) and by their cell structure (open or closed). Sealection 500 is a low density, open cell, flexible polyurethane foam.

The foam supplied by Insulfoam is completely different from any other product on the New Zealand market:

Insulfoam is spray-applied as a liquid, expands into foam to fill gaps and cracks, and then sets within seconds.

Other foams are pumped pre-expanded through holes drilled in the wall.

Insulfoam sticks to the substrate and therefore can be applied under floors, under rooves and in walls (where there is no lining so that the wall is exposed).
Other foams are injected into existing walls only.

Insulfoam is an environmentally-friendly water blown polyurethane foam.  The foam is inert and emits no toxins during installation or after.

Other foams are Urea Formaldehyde-based which are banned in North America.

Insulfoam maintains its shape and R Value over time.

Other foams shrink by up to 6% as they dry, leaving gaps which affect insulation performance.
