Spray foam, answered
Still have a question? Our team is happy to help – call or request a free inspection.
What is spray foam insulation and how does it work?
Spray foam insulation is applied as a liquid that expands on contact to fill gaps, cracks, and cavities within a structure. Once cured, it forms a continuous, airtight insulation layer that improves thermal performance, reduces air leakage, and helps control moisture movement throughout the building.
How much does spray foam insulation cost in Sydney?
Spray foam insulation cost in Sydney and surrounding regions varies depending on factors such as the size of the area, the type of foam used, access conditions, and required insulation thickness. We provide tailored, fixed-price quotes following a site assessment to ensure accurate pricing and performance outcomes.
What warranties and guarantees do you offer?
All spray foam insulation systems installed by Foamed Insulations are backed by manufacturer warranties covering both materials and workmanship. Our professional installation standards and proven products provide long-term assurance, giving clients confidence in the durability, performance, and reliability of their insulation investment.
How long does spray foam insulation take to install?
Most standalone homes and small commercial projects are completed in one day. Larger industrial or multi-stage installations may require additional time, but our team always provides an accurate schedule upfront.
Can I remain in my home during applications?
For safety and optimal curing, homeowners typically vacate for a few hours while foam is applied and set. Once the area is ventilated and safe, you can return home.
Is spray foam insulation safe for my home?
Yes. When installed by trained and qualified professionals, spray foam insulation is safe for residential use. Once cured, the material is inert and stable. Proper installation, ventilation during application, and adherence to safety guidelines ensure a safe and effective insulation solution.
Can spray foam be used in existing homes?
Spray foam insulation is well-suited to existing homes and retrofit projects. It can be applied to underfloor areas, and hard-to-reach sections where traditional insulation struggles to perform, improving comfort and energy efficiency without major structural changes.
What is the difference between open-cell and closed-cell foam?
Closed-cell foam is our preferred choice for underfloor insulation because it delivers superior strength, moisture resistance and energy efficiency. Open-cell foam is lighter and generally used for specialised applications such as vermin-proofing. Closed-cell foam is denser, adds structural rigidity, creates a vapour barrier and achieves a higher R-value for the same thickness as other insulations, perfect for roofs, floors and pre-insulated pipes.
