Premium Services for Underfloor Insulation

Spray Foam Australia stands as a pioneer in the industry of underfloor insulation, with a specific focus on retrofitting existing homes in Sydney, Brisbane, and Perth to augment their energy efficiency and comfort levels.

We offer a diverse range of underfloor insulation solutions, each customised to enhance the R-value of your home, regardless of whether it features a concrete slab, a concrete floor, or timber floor joists. Having insulated over 10,000 homes in Australia, we possess the requisite expertise and skills to provide service of unmatched quality.

The Crucial Role of Underfloor Insulation

Underfloor insulation parallels wall insulation and ceiling insulation in acting as an extremely effective barrier against heat gain and heat loss, accounting for approximately 15-25% of thermal and heat loss from your home. Efficient insulation results in substantial energy savings, diminished energy bills, and a smaller carbon footprint.Poorly insulated suspended timber floors can contribute to a multitude of heating and cooling problems:

Heat Loss and Gain: Inadequate underfloor insulation can cause significant heat transfer. During winter, heat from inside the building escapes through the floor, while in summer, heat from outside can penetrate through.


Draughts: Gaps and cracks in the floorboards can let in cold air, creating uncomfortable draughts. This can cause the overall temperature of a room to drop, requiring heating and cooling systems to work harder.

Moisture Issues: Suspended floors, especially in older buildings, can contribute to problems related to cold winter moisture in underfloors and cavity walls. This moisture can make cool air in the home feel colder and lead to dampness, mold, and hidden rot issues.


Vermin Deterrent: Uninsulated timber floors can provide entry points and nesting areas for rodents and insects. 

Increased Energy Costs: Non-insulated suspended floors can lead to increased energy usage as heating and cooling systems work overtime. 

Selecting the Right Underfloor Insulation Products

We provide two main types of underfloor thermal insulation products: Insulation Batts and Closed Cell Polyurethane Spray Foam. Each product comes with its unique advantages and considerations to guide your decision-making process.

Closed-cell spray foam insulation is the preferred choice for floor insulation, ceiling insulation, and wall insulation due to its innovative application process. It adheres directly to the underlying structure, offering comprehensive airtightness, superior heat retention capabilities, effective moisture management, sound dampening, and reinforced structural strength.

"Using Closed Cell Spray Foam installed by our certified installers, we will maximise your homes energy efficiency by a further ~25%, saving you BIG on heating and cooling running costs."

Thermal & Structural
Performance

Closed-cell spray foam insulation has the highest R-value of any insulation material, providing excellent thermal insulation and reducing energy costs.

Closed-cell spray foam insulation can increase the structural strength of a building by up to 300%, making it an excellent choice for areas prone to high winds, hurricanes, or earthquakes.

Air & Sound
Performance

Acts as a complete air barrier, which prevents air leakage and drafts, improving indoor air quality and reducing heating and cooling costs.

Reduces noise transmission by reducing vibrations making it an ideal choice for added soundproofing.

Water Barrier
Performance

Impermeable to water, which means it prevents mold and mildew growth.
It will also reduce the risk of water damage to the building structure.

Environmental & Sustainable

Closed-cell spray foam insulation is made with sustainable resources and is free of harmful chemicals such as formaldehyde and CFCs.

It also have certified VOC's with 100% off-gassing within 24 hrs.

Longevity & Integrity
Perfromance

Closed-cell spray foam insulation is long-lasting and doesn't degrade over time, unlike some other types of insulation.
