I am no longer even convinced that the product works, at least not any significant insulating properties. They have supposedly done trials in numerous industries over the last 7-8 years, yet they can report NO meaningful repeat sales or major customers that have standardized on the product. Lest someone mention Boral, I would remind them that the deal with Boral is to give Boral exclusive distributorship to sell the product. How has that worked for ya? In over a year Boral hasn't increased sales of product. Which tells me that they are not using the product on their own roofing materials.
I don't see anything on the Boral website about a "NEW" technology roof tile that is a "Paradigm shift" in the industry. All that is typical INTK, (Stu), Press Release BS. Which suckered most of us in the past.
To say caution is warranted, would be the understatement of the decade.
