FSC & aluminum wood clad windows total $$ cost for wood budget

Hello - We are using a very expensive aluminum wood clad window system for a project. My question is, how does this window system factor into the total wood budget $$ amount. It is looking like we cannot get the wood in this window system to be FSC certified wood. If the window system cost contributes fully to the wood budget number, it will be difficult for this project to achieve MRc7. Has anyone had experience with this? I doubt it would be possible to get a $$ break out for just the wood used within the window system. Thanks!
