The ASTM D4803 is a standard test method for predicting the heat build-up in a material. Heat build-up relates to the amount of heat absorbed by a surface, which then increases the ambient air temperature around the material and on the material’s reverse side. Heat build-up is the reason the temperature in uninsulated structures such as shipping containers and modular buildings can rise considerably when exposed to prolonged sunshine and hot external temperatures.
Testing Zenova IP:
A 0.048” thick piece of steel sheet had a 1.33mm coating of Zenova IP thermal insulation paint applied to one side. Alongside this, an untreated 0.048” thick piece of steel sheet was used as a control specimen.
Heat build-up in the test samples was determined using a temperature exposure box equipped with a 250-watt white infrared heat lamp. The temperature was measured with thermocouples attached to the centre of the underside of the specimens and monitored with a digital thermometer. The heat source was energized, and the temperature monitored until such time that there was no
increase in temperature over a period of ten minutes. The maximum temperature was recorded for each specimen.
Testing Zenova IR:
A 0.048” thick piece of steel sheet had a 5mm coating of Zenova IR
thermal insulation render applied to one side. Alongside this, an untreated
0.048” thick piece of steel sheet was used as a control specimen.

Results with Zenova IP:
The test showed that the ambient air temperature on the underside of the steel sheet coated with 1.33mm of Zenova IP thermal insulation paint rose 55% less than the untreated control sample. This concluded that Zenova IP thermal insulation paint has excellent insulation qualities and can dramatically reduce heat absorption and the transfer of heat through sheet steel.

ZENOVA IR thermal insulating coating can be used on its own or mixed with concrete and plaster for a render application to internal and external walls in commercial and residential buildings to provide immediate insulation benefits.
This simple demonstration clearly shows how effective Zenova's Insulation Render is as a thermal barrier.
This simple demonstration shows Zenova IP's anti-condensation qualities, which prevents mould growth on surfaces, which is something that is a major problem for many homes, buildings, refrigerated vehicles and storage areas.
This demonstration shows how effective Zenova IP paint is at creating a thermal barrier.
Using a conventional frying pan and a portable gas stove, we will illustrate how effective Zenova IP is as a thermal barrier and insulator.
