pluto123 Thanks for the info about needing a flat floor to lay masonite. I have found a product at bunnings that is thicker (may add some warmth) and is also tounge and groove so may help to even the floor out. http://www.thelaminexgroup.com.au/downloads/trade_essentials/TradeGuide_Part_Flooring.pdf I know that this is going to cost a bit but it might be worth it. I am hoping that it is thick enough and the tounge and groove will make the floor more level. They do 19mm,22mm or a 25mm commercial. I am not worried about loosing 6 extra mm of headroom, would the thicker boards be the way to go for warmth and leveling out the floor??? I already have 2 houses with polished boards and find them quite cold. Where this house is located i really need to keep the warmth in and will also rent it so the boards need to be covered up. They would look stunning but being a holiday rental and in a freezing place i have decided not to go down that path.
Thanks Duckster I have never heard of masonite but the water resistant (tempered masonite) would be the go. Any other ideas of a good hard wood product to screw down???
