Technology
Insultec is applied in fluid form to the external surface and when dry forms a solid protective finish. It's unique formula will stop damage caused by Solar heat. It has also received from APAS certification under specification 1720/2 for encapsulation of asbestos sheeting.

New Insulated Roof:
Insultec would give a saving in air conditioning operating cost up to $5.16 per M 2
Existing Uninsulated Roof:
The savings are the same as above.
New Insulated Roof:
For new buildings insulated with fibreglass batts or similar on a metal deck roof would give a reduction in air conditioning cost of approximately $1.12 per M 2 per year.
Insultec versus other Insulations:
Insultec gives a 6°C lower than 2.5 pink batts. Pink batts are not effective in keeping the maximum daytime temperature at a low value.
White Paint: is 33% less effective than Insultec

REPORTS
Performance of Insultec membranes as Heat –Rejecting Coatings.
University of New South Wales. Emeritus Professor H.J. Goldsmid
3rd May 1993
As a result of tests carried out I have been convinced of the remarkable properties of Insultec.
In my experience even when conditions were not so ideal in central Sydney it is possible to achieve a difference of 10°C.
Comparisons with fibreglass batts: The use of an “R” value is unrealistic for Insultec since it does not rely solely on a reduction of thermal conduction for its operation. An Insultec coated enclosure would remain at much lower temperature since the external surface would stay cool. In other words conventional heat insulating materials tend to delay the ingress of heat where as Insultec also provides continuous rejection of heat.
Ordinary paints are greatly inferior to Insultec in their overall heat rejection.
Insultec Liquid Insulation
Dr R Cammarano Consulting Services Perth WA. 13 th June 1995
Review of previous experimental work conducted on the efficacy of “Insultec” All results indicate that an enclosure coated with Insultec was significantly
cooler, of the order of 5-15°C, the variation in temperature difference is dependant on ambient air temperature and climatic conditions.
The astonishing results suggest that Insultec may be more effective than conventional insulation such as fibreglass batts to minimise internal air temperatures. It was found that a Insultec coated shed was 10% cooler than a fibreglass batt insulated shed.
