CORK SPRAY COATING
Therma Protect Plus
Therma Protect Plus is an Australian-made coating, applied here as a cork spray for interior and exterior walls, roofs, decks and patios. It’s cork bark ground into granules and sprayed on in a flexible Therma Protect Plus binder at around 3mm thick – thick enough to genuinely insulate and waterproof, not just change the colour of the wall.
How Therma Protect Plus cork spray performs on your wall
The Origin of Our Cork


Cork comes from the bark of the cork oak, Quercus suber, native to the Mediterranean. Bark is stripped by hand roughly every nine years, and the tree keeps standing and producing for well over a century.
The tree is never cut down. That’s the whole environmental case for cork, and it doesn’t need dressing up – a renewable harvest from a tree that keeps growing.
Stop your house heat, block the moisture, stop the cracking
The Benefits of Therma Protect Plus Cork Spray Coating
Here’s what a coat of Therma Protect Plus actually does for your home:
- Cooler in summer, warmer in winter – cork’s sealed air-pocket structure slows heat transfer both ways
- Lower energy bills – less reliance on air conditioning and heating to hold the temperature
- Genuinely renewable – harvested from bark that regrows, without felling the tree
- Won’t crack – flexes with the wall through heat and temperature swings, where render splits
- Dampens noise – the same air-pocket structure that slows heat also absorbs sound
- Resists mould and pests – the coating doesn’t give either anywhere to establish
- Better indoor air – helps regulate humidity rather than trapping it
