Where Spray Foam Excels
Underfloor Insulation
Spray foam improves underfloor performance by blocking cold air, pests and moisture from entering through gaps. It offers long-term protection for timber and enhances your overall heat retention.
Work Sheds & Garages
Metal sheds benefit from spray foam’s ability to eliminate moisture-prone pockets. Its expansion fills every indentation, keeping your workspace insulated, dry and ready for everyday use.
Caravans, Vans & Tiny Homes
Spray foam insulation helps micro-living spaces feel more stable and comfortable. Its airtight seal prevents heat loss and muffles outside noise, creating a better environment on the move.
Shipping Containers
By bonding directly to the steel, spray foam removes the thermal weaknesses of container walls. It creates a smooth, insulated finish designed to stop condensation and deliver year-round comfort.
Marine Applications & Soundproofing
Spray foam makes boats quieter and more resilient. It reduces vibrations from engines, seals internal walls and shields surfaces from moisture damage and corrosion.
Frequently Asked Questions
Why is insulation important for coastal homes?
Coastal homes are exposed to moisture, salty air and fluctuating temperatures, which can cause condensation, corrosion and higher energy use. Proper insulation protects against these issues by creating a thermal and moisture barrier. Spray foam insulation is especially effective because it adheres directly to surfaces, preventing damp air from seeping in and improving energy efficiency, comfort and longevity of building materials.
Can insulation reduce condensation and mould near the coast?
Yes. Insulation helps regulate surface temperatures inside your home, reducing the conditions that lead to condensation and mould. Spray foam insulation forms a waterproof, airtight layer that keeps warm, humid air from meeting cool surfaces — a common problem in coastal climates like Shellharbour. This prevents mould growth, protects your walls and floors, and keeps indoor air healthier.
How does insulation help with energy efficiency?
Insulation acts as a thermal shield, keeping your home warmer in winter and cooler in summer. It reduces heat transfer through walls, floors and ceilings, which means your air conditioning and heating systems don’t have to work as hard. This leads to lower energy bills and a more sustainable, environmentally friendly home — benefits that are especially valuable in energy-conscious regions like Shellharbour.
