Here is the massage I have been sending to other contractors in Phoenix –

I am an inventor with 36 new products, one of which is the best rooftop ever made. How do I know? Because I got the design from CSR Edmonds in Australia and THEY HAD the highest performance until I improved on their design. 

Here is their design and mine – their turbine top is the heart of the performance. It is a better rain hat than any other in America. 

Here is the data compared to two of the top American sources. 

Jay, please email me and text me when you do, to tell me if you are the right person to spread this information out to those engineers who specify rooftop ventilators. em is kurt@inviscoinc.com
