When compared to traditional forms of insulation, closed cell spray foam insulation offers a higher R-value, establishing itself as a superior thermal barrier. This results in enhanced energy efficiency and ultimately leads to lower heating and cooling costs, particularly for homeowners in Mid North Coast NSW.
Spray foam insulation, particularly closed cell spray foam, expands to over 30x its size, effectively filling in gaps and holes. This process significantly enhances energy efficiency by eliminating air leakage and controlling drafts, making your home more comfortable during colder weather on the Mid North Coast NSW.
Closed cell spray foam insulation offers exceptional longevity, with a lifespan that can reach up to 80 years, making it an excellent choice for enhancing energy efficiency in homes across the Mid North Coast NSW.
Spray foam insulation, specifically our closed cell variety, is manufactured with zero ozone depletion potential (ODP) and low global warming potential (GWP) blowing agents, enhancing energy efficiency. We use Huntsman Heatlok Eco, which is produced using recycled PET bottles, making it an ideal choice for insulation in the Mid North Coast NSW.
Spray foam insulation, particularly the closed cell type, creates a moisture barrier and is mould resistant. This type of insulation is highly recommended for homes in flood prone areas on the Mid North Coast NSW, as it is fully water submersible and enhances energy efficiency.
Rodents love to nest in conventional fibre glass insulation batts, which can compromise energy efficiency. However, using closed cell spray foam insulation acts as a rodent deterrent, helping to keep your house critter-free on the Mid North Coast NSW.

Every insulation has their advantages in different applications, not one type will suit all projects. However, spray foam outperforms traditional insulation batts on several aspects.
Closed/open cell refers to the density of the spray foam product.
Closed cell spray foam is denser, harder, has a higher R-value and moisture resistance. It expands less and is ideal for small spaces.
Open cell spray insulation has cheaper, lighter, quicker to apply and expands more. However, it does have poorer thermal insulation qualities.
Other than in residential wall and underfloor applications, closed cell spray foam insulation can be used in:
Factors such as the thickness required, size of the area to be sprayed and preparation work are all considered when supplying your quote.
In some situations, spray foam is more expensive. However, unlike traditional batts there is lower costs with installation. The financial investment made in using spray foam will be repaid in its longevity and superior insulation ability that will save you on heating and cooling costs.
Yes.
Spray foam insulation does give off fumes during the installation process known as 'off-gassing'. We recommend that householders and pets are not in the home while it is being sprayed and for 12-24hours afterwards. Following this the home is safe to live in.
This is dependent on the size of the area to be sprayed.
In domestic households it can take 1-2 days.
Airtight Insulation uses Huntsman Heatlok Eco, a product which is composed of 20% recycled PET bottles. The product also uses ultra-low GWP blowing agents.
