Insulating Concrete Tiles

Concrete tiles absorb heat…they are a Thermal Mass!

A single tile painted with Super Therm® dropped the temperature from 60°C to 26°C on a 24°C day

The design of most concrete and concrete tiles (including terracotta). With regular roof painting or roof restoration a concrete tiled roof can virtually last a very long time, however the average tiled home owner is rarely this proactive in roof maintenance and restoration.

In summer, a building with concrete surfaces can experience increased internal temperatures due to concrete’s high thermal mass. This effect can lead to:

  1. Higher Cooling Costs: As the concrete absorbs and stores heat from the sun, the interior of the building may become warmer, leading to increased use of air conditioning and, consequently, higher energy bills.
  2. Thermal Discomfort: The slow release of heat absorbed during the day can make the building uncomfortable for occupants, especially during the night when it is expected to cool down.
  3. Increased Energy Demand: The need for cooling to maintain comfortable temperatures inside buildings contributes to higher overall energy demand, which can strain energy resources and increase greenhouse gas emissions.

Implementing energy-efficient designs and coatings can mitigate these effects, improving thermal comfort and reducing energy costs.

Trapped Heat in the Roof

Concrete roofs can trap heat in the roof space. The thermal mass of concrete allows it to absorb a significant amount of heat from sunlight. Without adequate insulation or ventilation, the heat absorbed by the roof during the day can be trapped in the roof space, causing temperatures to rise significantly. This heat can then radiate into living spaces below, increasing the interior temperature and leading to higher cooling costs.

Applying Super Therm® heat block insulation coating, on roof tiles can significantly help in blocking the heat load. Super Therm® is designed to reflect and block 96.1% of the solar spectrum, including visible light, ultraviolet (UV), and infrared (IR) rays, which are primarily responsible for heat buildup. By reflecting and blocking these rays, Super Therm® reduces the amount of heat absorbed by the roof tiles, thereby minimising the heat transfer into the roof space and subsequently into the building. This can lead to a cooler interior environment, reduce the need for air conditioning, and lead to energy savings. Additionally, it can contribute to extending the lifespan of the roof by protecting it from UV and heat damage.

Concrete Thermal Mass Cooling

Discover the ultimate solution for cooling concrete with Super Therm®! Our revolutionary coating blocks an impressive 96.1% of total solar heat, keeping your thermal mass cool even on scorching days. In this video, witness the incredible difference as we apply Super Therm® to a concrete house in Unley, South Australia.

Despite temperatures soaring over 40°C on the surface, the section treated with Super Therm® remains comfortably in the high 20s, while the unprotected area climbs even higher. By blocking the solar heat load from penetrating the surface, Super Therm® ensures your concrete stays below ambient temperature. Compared to surrounding materials, Super Therm® coated surfaces can be over 50% cooler than other materials, providing unparalleled comfort and energy efficiency.
