I'd like to put new flooring in a 15x20' room. In order to keep the cost
down and for better wear, I was thinking of using "chipboard", similar to
plywood, but made of strands of wood, or chips of wood, and then
polyurethane. Years back a friend mentioned that she had seen it done in a
house, so someone has done it, but I don't know the construction details.
One thing that concerned me, well maybe two:
1. I assume I'd screw the chipboard into the (E) 2x T&G decking that is
the current (sub)floor in the room. I hadn't planned on countersinking and
filling the screw holes because the look isn't that important for the
What's the minimum field and edge spacing I could get away with?
2. Would it be necessary to leave spacing between the 4x8 panels? If
there is no space, would the panels buckle with changes in temperature?
3. Any ideas on making the chipboard panels into a "floating floor? Not
screwed to the subfloor, but with all the edges glued to each other (and
perhaps, glued along the edges and sides to a thin piece of plywood). If
it isn't screwed to the subfloor, any expansion wouldn't buckle the
panels. If so what sort of glue or adhesive work best?
