Where Spray Foam Excels
Underfloor Insulation
Spray foam strengthens your home’s thermal barrier by sealing the underfloor area completely. It reduces drafts, blocks moisture and supports better indoor comfort throughout the year.
Work Sheds & Garages
For sheds and garages made from Colorbond or steel, spray foam helps maintain a stable internal climate. By filling the grooves in metal panels, it keeps condensation under control and improves usability.
Caravans, Vans & Tiny Homes
Spray foam delivers efficient, space-saving insulation for mobile and compact dwellings. It fits everywhere traditional insulation fails, improving temperature control and reducing external noise.
Shipping Containers
With spray foam, shipping containers become more versatile spaces. The foam fills ridged walls to create an even, insulated interior that resists condensation and maintains consistent temperatures.
Marine Applications & Soundproofing
Spray foam’s density makes it great for reducing sound transfer and providing a waterproof layer inside boats. It improves onboard comfort and helps protect internal surfaces from rust.
Frequently Asked Questions
How does insulation help during cold winters?
Insulation slows the transfer of heat between your home and the outdoors, keeping interiors warmer for longer. In cold climates like the Southern Highlands, it helps maintain steady indoor temperatures while reducing the strain on heating systems. Quality insulation prevents cold drafts, stops condensation on surfaces and lowers energy use — keeping rooms comfortable even when it’s freezing outside.
How thick should insulation be?
The ideal insulation thickness depends on the product and the area being insulated. In colder climates, thicker layers are often recommended to achieve a higher R-value (a measure of thermal resistance). Spray foam insulation achieves strong performance even at thinner layers compared to traditional batts, making it an effective choice where space is limited but efficiency is crucial.
Is spray foam insulation environmentally friendly?
Spray foam insulation supports sustainability by improving a building’s energy efficiency. By reducing heat loss and preventing air leaks, it cuts down on the need for constant heating or cooling, which lowers carbon emissions. Many modern foams are also formulated with low-VOC or environmentally safe compounds. The long lifespan of spray foam further reduces waste, making it an energy-smart, low-maintenance insulation choice.
