Super Therm® High Performance Solar Heat Block Coating Adelaide Test
Testing conditions
- Temperature coating applied, sunny 32°c humidity 15%
- Temperature measured, sunny 35°c humidity 12%
4 standard sheets of 0.6mm Galvanised metal were used as test sheets for the application of Super Therm®. The test was filmed to show the ease of mixing and application and the results were approximately 21 days following application. This was a field test conduced with:
- Uncoated galvanised sheet (300mm x 300mm)
- 1 coat of Super Therm®
- 1 coat of Super Therm® with 1 coat of dark Space Grey paint
- 2 coats of Super Therm® with 1 coat of dark Space Grey paint
Note: In this test one brush coat of Super Therm® is equivalent to 5-7 mil dry. SPI Coatings the manufacturer always recommend 2 coats by brush to achieve the 10 mil dry thickness. The Sheet 2 reading on top is not fully accurate for this reason, however the efficiency of Super Therm® underneath has achieved just above ambient results.
As the Thermo images below show with a spot metre temperature reading the galvanised sheeting showed a 2% increase in temperature under the sheet. All the Super Therm® insulated sheets were between 12% and 23% better underneath with their temperature readings.
A 6° reduction in the thermostat produces a 39% reduction in electricity costs (Con Edison). This test has indicated with a dark roof it would be 13° (22%) difference and improvement with Super Therm®.
Super Therm® (Sheet 2) with just one coat was only 2°c higher on the underside than the ambient temperature of 35°c.
Although we did not test a coat of Space Grey on an uncoated galvansied sheet we estimate even at a conservative 2% increase the underside temperature would be 57° in relation to the 44.8° recorded with Super Therm® which is a 22% difference.
NOTE: We do not recommend applying dark paint over Super Therm® as it blocks the throw off of the radiation heat and blocks emissivity from leaving the surface. We recommend using HSC™ if using dark colours. The Space Grey used in this test was for testing purposes only.
