Underfloor Insulation Installers

Drastically reduce excess energy loss within your home by insulating your underfloor. Working with our insulation installers means keeping the floor of your home warm, comfortable, and quiet year-round.

The cold truth
The Australian Government estimates up to 20% of a home’s internal heat is lost through its walls, with the same percentage of outside heat placing pressure on our cooling units during the summer.

Uninsulated underfloors

Few things are as uncomfortable as stepping onto a freezing floor or feeling a chilling gust of air at your feet through the gaps in your underfloor. Unfortunately, failing to insulate your underfloor not only contributes to reducing the comfort of your home but is also a major contributor to increased energy bills.

Energy efficiency at your feet

Our team uses industry-leading technology and equipment to eliminate draught spots from your underfloor. We use spray foam insulation to create a barrier that prevents heat from seeping out during the winter while blocking unwanted heat from entering during summer. This means you’ll enjoy a cozy, well-insulated underfloor regardless of the season.

The key benefits

Lower Energy Bills

Underfloor insulation prevents heat loss in the winter, and heat gain in the summer, keeping your floor comfortable year-round. This adds up to substantial energy savings long-term.

Spray foam’s noise-dampening capabilities make it excellent for privacy. This helps minimise disruptive echoes and noise transmission between rooms.

What to expect

At Spray Foam Insulation Tasmania, we understand every project comes with a unique set of challenges. That’s why we take the time to understand your needs and desired results. Above all, our team values honesty and integrity – we’ll never suggest a solution unless we’re confident it’s right for you.

Brief Chat

All of our residential insulation projects start with a quick conversation with one of our friendly staff members. We’ll ask you a few questions about your home, including what current forms of insulation you have, issues with heating your home, and if you’re noticing draughts etc. Our staff member will then typically email you a few informational PDF brochures along with our pricing structures.

Don’t hesitate to contact us again if you have any more questions or would like to discuss your options!

Thermal Performance Assessment

Next, we’ll inspect your entire home with our state-of-the-art thermal imaging camera. This allows us to precisely identify draught spots, defective insulation, and inadequately insulated sections of your living space.

Thermal imaging is quick, accurate, and gives our team complete confidence that we’re addressing your home’s most critical areas.

Electrical Compliance

It’s the law to assess your home first by a Licenced Electrician before applying insulation to a living space. We thoroughly evaluate all potential electrical risks during planning and installation. For example, when applying insulation, cables must be provided with enough space to dissipate heat. An improper installation can result in inconvenient circuit tripping or, worse, cause a fire.

Our team members are licenced Electrical Contractors (LIC# 871947842) to ensure every installation aligns with residential construction legislation.

Insulate your Underfloor

Once all checks have been ticked off, our team will thoroughly insulate your underfloor. When it comes to underfloor insulation projects, our preferred method of insulation is spray foam insulation due to its ability to block cold draughts, improve heat retention and strength, and reduce annoying squeaking. This process typically takes about 6 to 7 hours to complete.

It’s important to note that every home is different and comes with its own unique set of requirements. This means we may recommend alternatives depending on what we’ve uncovered during the checks.

"We were after some under floor insulation and after researching the options around, these guys seemed like the obvious choice. We had an idea of what to expect but our expectations were blown. Within hours, a massive change was seen. The heaters hardly had to be switched on and the floor had a much “softer” feel to it. Couldn’t be happier with the end results and we’ll be recommending these guys and their product to everyone!"

Residential Customer

"[…] we just wanted to advise that your predictions regarding the benefits of Spray foam are absolutely 100% correct and true! The wooden floorboards have all tightened up and sound and feel totally different under foot. Closing all those gaps between weatherboard and foundation concrete have made a real change to the ambient temperature of the house interior too! Thanks again for getting the job done so quickly and efficiently […]"
