ThermoCore Roof SIPs - 8" Panels
Anyone here use or have any experience with the ThermoCore SIPs? They are based out of Indiana and have a 8" polyurethane SIP ( I know about the blowing agents) with a R-50 value that I am considering using for my roof. Zone 4B
Some key points:
1 - I will be air sealing all interior panel joints with a T&G connection, caulk, gasket, and finally a peel & stick tape to ensure complete air tightness.
2 - I will use an ERV
3 - On the exterior I plan on putting a peel & stick butyl membrane that is vapor impermeable and then a standing seam metal roof.
If all these measures are done to ensure air tightness in a dry climate Zone 4B , I am hoping that I am safe from "sip rot". The reason for NOT doing a cold roof is that it is a wildfire area and doing a cold roof would allow embers to enter between the OSB cold roof panel the the SIP. This would create a fire potential.
Any comments about ThermoCore and the above install approach would be appreciated....
