I want to lay a solid timber floor for a new house. The substrate is 22mm STRUCTAflor ( Particleboard) on engineered I-Joists. I have been advised that I can glue the boards directly to the STRUCTAflor using the "plank on ply" method.


I plan to use wide boards 150 -180 mm X 14 mm of either Sydney Blue gum or Brushbox or Karri

My question is - do I really need to use T+G boards or can I use square dressed planks? What purpose does the T+G serve when glued on top of ply?




Thanks in advance
