Thank you for checking on the roofing material and confirming the S327. As we all know the Pro-Chain company has been less then honest with us in fact they have not told us the truth yet! Please make sure the JianLi and MWP is double checks when the material comes to the site. BEFORE they start to install!!!
As Ryan has pointed out there are maybe 4 different membrane materials and ONLY the S327 is FM approved. Before they install we need 3rd party approval on the material.
