Spray Foam insulation creates a protective thermal barrier beneath your home, reducing cold floors, draughts and escaping warmth while helping lower the energy needed to keep your home comfortable.

| Spray Foam Vs. Batts Insulation | Spray Foam | Batts |
|---|---|---|
Protects against conductive heat loss (R-Value)?Both materials resist conductive heat loss at equal R-value; the real difference lies elsewhere in this table. |
Yes | Yes |
Is an air barrier and stops subfloor air becoming indoor breathing air?Spray foam seals the subfloor as a continuous air barrier; batts are porous and let air pass through. |
Yes | No |
Stops rodents from entering the home and does not provide an attractive nesting location?Spray foam removes the gaps and moisture that make batt-insulated subfloors an appealing nesting spot for pests. |
Yes | No |
Maintains full R-value over time and won't sag or become dislodged?Spray foam stays permanently fixed in place, while clipped batts commonly sag or fall over time. |
Yes | No |
Will not absorb and trap moisture which can cause mould and wood rot?Closed-cell spray foam won't absorb water; batts readily trap moisture, creating conditions mould and rot need. [4] |
Yes | No |
Seals the subfloor perimeter, which accounts for 19% of winter heat loss?Spray foam fully seals the subfloor perimeter, the single largest source of winter heat loss. |
Yes | No |
Installs without gaps or compression which decreases performance by 50%?Spray foam fills every gap with zero compression; a 5% batt gap can halve performance. |
Yes | No |
Maintains performance despite thermal bridging from floor joists?Spray foam's continuous layer isn't interrupted by floor joists, which cut batt performance by 25–40%. |
Yes | No |
Guaranteed to maintain R-value for the life of the building?Spray foam is a permanent installation with a lifetime guarantee; batts degrade and need replacing. |
Yes | No |
Resists performance loss from wind wash in the subfloor?Wind moving through a vented subfloor strips heat through batts, cutting performance by roughly a third. |
Yes | No |
Formaldehyde-free?Spray foam contains no formaldehyde. |
Yes | No |
Recommended for subfloor installation by the US Department of Energy?The US DOE identifies batt insulation in vented crawlspaces as carrying higher moisture and rot risk. |
Yes | No |
Spray foam insulation transforms a leaky underfloor into a thermally efficient barrier — eliminating draughts, improving comfort, and cutting energy bills. Our Australian-made, concrete-like foam seals out winter heat loss and summer heat gain, keeping your home comfortable year-round. Installed by an experienced Tasmanian team using industry-leading equipment, it means less wasted energy and potentially thousands in long-term savings
If you own an older Tasmanian home, there’s a good chance you have hardwood floors on raised foundations — meaning icy floorboards and cold draughts creeping through the gaps. Left uninsulated, or insulated incorrectly, your underfloor quickly becomes a real problem, lowering comfort and driving up energy bills.
Your Home Isn’t a DIY Experiment
Problems can occur when the wrong product is chosen, existing moisture is missed or spray foam is applied incorrectly.
A trained installer will assess your home, determine where spray foam is suitable and apply it correctly, helping prevent avoidable problems and ensuring lasting performance.
