What is spray foam?

Spray foam is made from specially blended polyurethane components called ‘systems’. It can be sprayed into walls, ceilings, and other areas that need to be insulated including encasing pools and spas.

As the foam cures it expands to fill any gaps and will create an airtight and water-resistant seal while also improving the structural integrity of the home from within the wall cavity. 

While loose packed fibreglass blankets or batts can settle over time and create an invisible void or gap in your environmental barrier the rigid nature of spray foam ensures that it remains in place for the life of the building.

Properly installed foam insulation is intended to prevent the home from becoming too hot in summer and too cold in winter, helping to reduce the amount of air-conditioning needed to regulate the interior.

The most obvious benefit to the homeowner is the reduction of their energy bill and ultimately their carbon footprint.

The ease of application and ability to penetrate into cavities enables spray foam to create a more efficient seal against drafts, insects and vermin that will try to enter the home.

What to look for when selecting a spray foam for your home

·         Properly specified foam insulation should have a higher ‘’ than traditional fibreglass insulation and panels or cladding made from polystyrene products - compare the R-Value against the product thickness, spray foam can be applied at almost any thickness to provide an R-Value that meets your individual needs.

·         Spray foam insulation is generally fire retarded - remember to always check the manufacturer’s data before approving any application.

·         Not all spray foams are equal - compare R-Value and post cure shrinkage. You don’t want to pay for 50mm of insulation only to find that you have 25mm behind your walls with gaps that let your air-conditioning dollars flow out while allowing pests an easy way in.

·         Due to the need for specialised application equipment and an understanding of correct foam specification any installation should always be carried out by a professional spray foam applicator.

·         Don’t be afraid to contact the manufacturer - it is their job to help you understand what their product can do for you.
