Leaders in Under Floor Insulation with Spray Foam

Using spray foam insulation for under floors will maximise the energy efficiency of your home

Operating in New South Wales, QueenslandVictoria, &  Western Australia.

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."

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.
