Currently repairing/redoing my old (40s-50s) lean-to single-pitch roof. I've ended up ordering some TLX gold to bolster 50mm celotex between 4x2' rafters. Rafter size is imited by the window above the abutment/ledger plate and the window directly below the wall plate. RSJ purlin has been installed to support the rafters at middle of their span. I've also got some skylights to put in to give the room some more light, has anyone had any experience with TLX gold and fitting it around roof lights?
