Floating Floor.
I am going to lay a floating floor in the extension, but wanted to run how I am going to do it passed you guys to see if I have this right.
We have built off a concrete slab, so the surface of that slab is the current floor. As I understand it I have to cover the concrete with a membrane. (1200 Gauge, 300 Micron) The edges must come up the wall until it meets the DPC that sticks out into the room. It sticks out at about 40mm and is one brick in height above the concrete base. Then the DPM is bent down and taped to the Membrane.
The membrane will have to be joined, so it should be overlapped at about 300mm?
Should the joint be taped?
Sheets of 100mm insulation (2400 x 1200) will be placed on top of the membrane.
Should they be tight against the walls or should there be a gap?
Should the joints between the sheets be taped?
Flooring Grade chipboard 22mm (2400 x 600) will be placed on top.
Should the chipboard be tight against the walls or does it need room to expand slightly?
Should the joints be glued?
If so what type of adhesive is required?
One side of the boards are printed on (Manufacturers name etc) should this side be underneath?
I know there are several questions here but if anyone would care to give me some answers I'd be very grateful.
