Cpac Cool Roof System

[Trex52]

I am about 2 months away from putting a roof on a house I am building and was wondering if anyone has used, or anyone that knows someone that has used this for their roof? I have been searching for ridge venting on roofs, as it is used almost exclusively in the US now. CPAC is the only one that I can find that has something even close to this, here in Thailand. To hear them claim, as they should/would....it works great. However, I have yet to see any profound data on the results. We all know heat rises and heat dissipation is critical to helping keep a house cool, here in the tropics, with as little AC as possible. I have experienced the gore-tex phenonmenom back in the 90's and yes, theoretically it works....but I have used it in the Pacific Northwest and it will leave you wet to the bone after a while. So much for gimmicks, eh? This roofing system is not cheap, and would any savings ever pay off? Any input on this would be greatly appreciated. Thanks in advance. Trex
