week 10. flooring this week. treated plywood sheets for wet areas (kitchen, toilets and laundry) and chipboard sheets for dry areas (the rest of the house). to provide additional adhesion to the joists, slots are cut in the underfloor foil insulation for gluing. joints are also glued. glue must protrude out to ensure a good seal thus preventing water absorption at the end grain of sheets. sheets are nailed at crossing with floor joists as well as the perimeter. 10mm rebate along perimeter from face of boundary joists to allow for expansion.
