Expert Underfloor Insulation for Better Comfort and Energy Efficiency
Many Australian homes lose a lot of heat through the floor, especially those with suspended or raised timber floors.
The Your Home initiative says uninsulated floors can cause 10 to 20% of a home’s total heat loss. So, even if your walls and roof are insulated, cold air can still come in through the floor and reduce the benefits.
At Tates Coating Services, we understand that underfloor insulation is more than just adding material. It helps control airflow, cut down on heat loss, and make your home’s temperature more stable.
Upgrading your underfloor insulation can lower your heating bills, make your home more comfortable, and keep temperatures steady throughout the year.

What Is the Best Type of Underfloor Insulation?
Underfloor spaces can be tricky. There’s open airflow, moisture, pipes, wiring, and uneven framing to consider.
You have a few insulation options, like batts or rigid boards. These work well if they’re installed properly and kept safe from movement and moisture.
If there are gaps, sagging, or air moving under your home, insulation won’t work as well.
This is why many homeowners pick spray foam insulation. In homes with airflow, moisture, or uneven access, which is common in Perth, spray foam consistently outperforms other insulation methods.
Spray foam expands to fill spaces, seals gaps, and sticks to the structure, so it keeps working well over time.
Underfloor Insulation: The Spray Foam Advantage
Here’s why spray foam is often used in underfloor spaces:
- Expands to seal gaps, joints, and drafts
- Won’t sag, shift, or fall out over time
- Reduces airflow that carries moisture and cold air
- Ideal for tight, uneven spaces around pipes and wiring
- Maintains performance long term
This method prevents air from moving under your floor, where most heat loss begins.

How to Tell If It’s Time to Upgrade Your Underfloor Insulation
A lot of homes either don’t have underfloor insulation or have insulation that no longer works well. Many homeowners assume cold floors are just “how the house is” — but they’re often a sign of missing or failing underfloor insulation.
Here are some common signs:
- Floors feel cold even when heating is on
- Rooms lose heat quickly overnight
- Drafts coming through floorboards
- Higher than expected heating bills
- Uneven temperatures between rooms

- Check for moisture or structural issues
- Prepare the work area
Application
- Foam is applied directly to the underside of the floor by trained technicians
- Expands to seal gaps and edges
- Installed in layers for consistent coverage
Aftercare
- Final inspection of coverage and seal
- Site cleaned and access points secured
Every home is unique, so we adjust our installation method to fit your specific structure.
What Our Clients Say
“Just had Peter & Aaron spray the walls and underfloor of our home in Pingelly and couldn’t be happier. Really nice guys, and they couldn’t be more helpful and professional. Job was A1 and they left the place spotless in what turned out to be a really windy day.” – Tash & Noel
“I contacted Peter about domestic underfloor insulation. He gave me good advice and then organised a time for the job that suited me. The two technicians that arrived were friendly and went out of their way to minimise disruption. They did a great job, and the house is noticeably warmer on cold winter mornings. I wish I had done it years ago.” –Richard
“These guys were such a pleasure to deal with. From the initial quote to the insulation it was straightforward. They made sure they reached the hardest areas under the floor. Our floors are quieter and warmer.” – Aimee
“We couldn’t be happier with the results from our underfloor insulation. There are no drafts and the house holds temperature much better. Cold mornings outside and still comfortable inside. Our builder was impressed with the job and product.” – Nicolette & Adam
Frequently Asked Questions About Underfloor Insulation
The cost depends on your floor type, how easy it is to access, and the insulation material you choose. Spray foam costs more at first, but it gives better thermal performance, lowers energy bills, and lasts longer. For more details, read How Much Does Underfloor Insulation Cost?
How long insulation lasts depends on the material and how well it’s installed. Spray foam can last over 50 years without sagging or moving. Batts usually last 20 to 30 years, but might sag or get damaged. Foil boards can last 15 to 25 years if conditions are right. For more information, read How Long Does Spray Foam Insulation Last?
If your floors aren’t insulated, your home’s energy performance can suffer. Raised timber floors and gaps under the house let cold air move in, which pulls warmth out and makes it hard to keep a steady temperature. This can mean longer heating times, higher energy use, uneven room temperatures, and cold floors, especially in the morning. In some homes, floors can be 5 to 8°C colder than the air inside.

Even the best insulation won’t work well if it’s not installed properly. Gaps, uneven coverage, or sagging make it less effective. Installation should meet Australian Standards for safety and performance. A professional will help you choose the right product, apply it evenly, and make sure everything is up to code.
Spray foam gives strong thermal resistance and seals well. It expands to fill gaps, cuts down on air movement, and stays put over time. This makes it a good choice for underfloor areas where airflow and access are tricky. If you want to compare products, read Should I Use Spray Foam Or Batts For Insulation?
