Underfloor Insulation Perth & WA
Polyester underfloor insulation for Perth homes
Perth homes can be beautiful, breezy and full of character.
They can also be freezing underfoot in winter and uncomfortably hot in summer.
If your home has suspended timber floors, the space underneath your house can have a real impact on how comfortable the rooms feel above. In winter, cold air under the floor can make rooms harder to heat. In summer, hot air moving through the subfloor can add to the heat load inside your home.
Underfloor insulation helps create a thermal barrier beneath your floorboards, reducing heat transfer through the floor and improving comfort underfoot.
DIY underfloor insulation for Perth homes
Underfloor Insulation Australia supplies polyester underfloor insulation for DIY installation in Perth and can drop to freighters to deliver insulation outside of Perth.
In Perth, we supply Value Poly in a 450mm roll, a good-quality polyester underfloor insulation option designed to be installed between timber floor joists and stapled securely into place. It is actually manufactured in Perth, which keeps the freight costs down! Polymax is not available for WA customers.
Value Poly is a budget-friendly polyester insulation option that performs well when installed correctly and secured snugly against the underside of the floorboards.
For homes with safe and suitable access underneath, DIY underfloor insulation can be a practical way to improve comfort without paying someone else to do the crawling. And whether you are trying to take the bite out of winter floors or help your home cope better through a Perth summer, starting underneath the floor can make a lot of sense.
Comfort in winter and summer
A lot of people think about underfloor insulation only when their floors feel cold in winter. That is certainly one of the big reasons to install it.
But insulation is not just a winter product. Insulation helps slow heat transfer. In winter, that means helping reduce heat loss through the floor. In summer, it can help reduce heat gain from hot air beneath the house, especially in homes where the subfloor space becomes warm during the day.
It will not replace good shading, ceiling insulation, draught proofing or sensible cooling. Perth summer is not that easily defeated. But underfloor insulation can be an important part of making your home more comfortable year-round.
Is my home suitable for underfloor insulation?
Underfloor insulation is suitable for many Perth homes with suspended timber floors, but not every subfloor is ready for insulation straight away.
Before ordering, check that:
- there is enough room to move safely under the house
- the ground is reasonably dry
- there are no obvious damp, mould or rot issues
- there is no exposed or unsafe wiring
- there are no obvious asbestos risks
- pipes, ducts and other obstructions can be worked around
- the timber joists are accessible for stapling
If the space under your house looks more like an archaeological dig than a subfloor, it may need attention before you start insulating.
What else will I need?
For DIY underfloor insulation, you will usually need:
- Value Poly polyester underfloor insulation
- suitable galvanised staples
- a staple gun
- protective clothing
- a head torch or work light
- a cutting tool
- knee pads or something comfortable to crawl on
- patience
- possibly someone above the floor passing things down and making encouraging noises
Underfloor insulation is not technically complicated, but it is physical work. The better prepared you are before you crawl under the house, the less exciting the job becomes. And in this case, less exciting is good.
How much underfloor insulation do I need?
To work out how much insulation you need, you will need:
- the approximate floor area you want to insulate
- your joist spacing
- confirmation that 450mm wide insulation is suitable for your floor structure
Once you have those measurements, you can request pricing or work out how many rolls you need.
