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:
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.
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.
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.
