Hi all,
We're installing a plywood floor in our 1800's home. At the moment the room in question has a concrete floor (which at some point was put down to replace an original floating wood floor) with a pathway in the middle that is original hallway tiles (the rooms either side of the hall were combined to make one big room). The concrete sections have a damp proof membrane underneath, but the tiles up the centre of the room do not. We're going to be laying down a batten frame with insulating foam of some kind in between, and then attaching a tongue and groove plywood floor on top of that (which we will paint and use as a floor until we can afford a 'proper' floor). Our concern is that because of the 'break' in the DPM where the old tile section is that damp could get in under the new floor there. Should we put a DPM across the entire floor before laying the frame, insulation and ply or will creating this DPM 'sandwich' with a gap on the under side, cause a problem?
Thanks in advance for any advice! - we are newbie DIY-ers and are finding our way through every challenge with the help of google and forums!
