40+ Years of Expert Residential & Commercial Insulation Services
When performance matters, experience counts. Foamed Insulations is a leading insulation company in Sydney, delivering high-performance spray foam insulation solutions for homes, businesses, and industrial facilities across NSW.
With more than 40 years of industry experience, we specialise in insulation systems that improve energy efficiency, control moisture, and enhance long-term comfort. From large-scale commercial insulation projects to home insulation in Sydney, our work is engineered for real conditions.
As specialist insulation contractors Sydney clients trust, we deliver professional installation, transparent pricing, and insulation systems designed to perform for decades.
Home Insulation for Sydney Locals
Choosing the right insulation for your home directly impacts comfort, energy use, and long-term costs. Our residential home spray insulation services are tailored to Sydney’s climate and modern building standards.
We install both open-cell and closed-cell spray foam insulation, selecting the right system based on your home’s structure, airflow requirements, and thermal goals.
Our residential spray foam insulation applications include:
Underfloor Insulation
Homes with raised floors or subfloor cavities are particularly vulnerable to cold air infiltration and moisture issues. Underfloor spray foam insulation creates a continuous barrier beneath the home, reducing heat loss, improving comfort underfoot, and helping manage damp conditions common in many Sydney properties.
Commercial Insulation for Sydney Businesses
We deliver commercial spray foam insulation for a wide range of industries, providing durable, code-ready solutions that perform in demanding environments.
We deliver commercial spray foam insulation across the following applications:
Industrial and Warehouse Insulation
We insulate warehouses, factories, and industrial facilities to reduce energy consumption, improve temperature control, and protect equipment and stock.
Commercial Kitchens and Void Filling
Our spray foam systems are ideal for void filling in commercial kitchens and food preparation areas, including work requiring AS4674 compliance. Spray foam seals penetrations, controls airflow, and supports hygiene requirements.
Cold Storage and Refrigeration
Closed-cell spray foam insulation is widely used for cold rooms, refrigerated spaces, and temperature-controlled environments where moisture resistance and thermal stability are critical.
Office and Commercial Buildings
For offices and commercial buildings, spray foam insulation improves thermal performance, reduces noise transfer, and helps meet BASIX requirements.
Our team works closely with builders, facility managers, and consultants across commercial insulation projects in Sydney to ensure insulation systems integrate seamlessly with HVAC, fire safety, and building services.

- Size and scope of the area being insulated
- Choice between open-cell and closed-cell foam
- Accessibility of the space
- Required insulation thickness and performance level
While spray foam insulation typically has a higher upfront cost than traditional materials, it delivers long-term value through energy savings, reduced maintenance, and durability. Many clients find the investment pays for itself over time through lower heating and cooling costs.

Foam Insulation Sydney – FAQs
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 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.
