Keep the Heat Out with a Cooler Roof

Heat Reflective Roof Coatings

A dark or ageing roof soaks up the Australian sun and pushes that heat straight into the home below. Shieldcoat's Thermobond heat reflective roof coatings bounce solar heat back off the roof. Rooms stay cooler, the air-conditioning works less, and the roof gets a tough, long-lasting finish at the same time.

Proven to Cut Heat, Not Just Claimed

Cool roof coatings work, and we can show it. Independent testing by the Queensland University of Technology on Thermobond found that buildings with heavy air-conditioning or refrigeration use can save 25–30% of their yearly electricity bill. In a family home the bigger win is comfort: noticeably cooler rooms through the hottest months. Watch the explainer in Shieldcoat University

Why choose shieldcoat

Why Choose Shieldcoat for a Cooler Roof?

Shieldcoat is an Australian family-owned manufacturer, and our water-based roof coatings are made for Australian conditions. Thermobond pairs heat-reflective technology with the durability our Roofbond membrane is known for, so you don't trade protection for performance.

Lower Cooling Costs

Reflecting solar heat at the roof means less heat reaches the ceiling space and less load on your air-conditioning, all summer, every summer.

Colour Without Compromise

With Thermobond IR you don't have to choose a white roof to get a cooler one. Infra-red reflective pigments keep darker colours working hard too, with improved fade resistance.

Easy for Professionals to Apply

Like Roofbond, Thermobond sprays smoothly for an even, factory-like finish, making it a favourite with experienced roofers.

What you need to know to get started

Light or Dark: There's a Thermobond for It

Thermobond HRC gives maximum heat reflection in lighter colours. Thermobond IR uses infra-red reflective pigments to deflect heat even in darker colours that standard heat-reflective coatings can't manage.

Works on Tile and Metal Roofs

Thermobond goes on concrete tile and metal roofs as part of a full Shieldcoat system, with the right primer underneath for the surface.

Safe for Drinking Water Collection

Once fully cured, Thermobond is safe for roofs used to collect drinking water.

Built on Roofbond

Thermobond is the heat-reflective version of our Roofbond Roof Membrane, so you get the same proven durability and mould resistance, with a cooler roof on top.

Backed by a 10-Year Guarantee

Both Thermobond HRC and Thermobond IR carry a 10-year guarantee against the harsh Australian climate.

FAQ

Do heat reflective roof coatings really work?

Yes. Independent testing by the Queensland University of Technology on Thermobond showed buildings with heavy air-conditioning or refrigeration use can save 25–30% of their yearly electricity bill. Homes see a big improvement in comfort through summer.

What's the difference between Thermobond HRC and Thermobond IR?

Thermobond HRC is our maximum heat-reflective coating, best in lighter colours. Thermobond IR uses infra-red reflective pigments, so darker colours also reflect heat and resist fading.

Can I use a heat reflective coating on a dark roof?

Yes. That's what Thermobond IR is designed for. It improves solar reflectivity in darker colours that traditional heat-reflective coatings can't achieve.

Is a heat reflective roof safe for rainwater tanks?

Yes. Once fully cured, Thermobond HRC and Thermobond IR are safe for drinking water collection.

How long does a heat reflective roof coating last?

Thermobond HRC and Thermobond IR are both backed by a 10-year guarantee.

Can I apply it to a metal roof or tiles?

Yes. Thermobond suits both concrete tile and metal roofs when applied over the right Shieldcoat primer for the surface. Talk to a Shieldcoat distributor or applicator about the right system for your roof.
