A method of flooring using butting panels fixed to a frame primarily of joists, joints transverse of the longitudinal axes of the joists being largely unnogged. To support such joints unsupported by a framing element reliance is placed on panel edge to panel edge adhesion. In a preferred form particle board panels each provided with an edge groove have the effect of ensuring both a sufficient availability of adhesive for an effective butt joint whilst in addition, providing a keying or splining between the adjacent panels.

Why it's free to use
- Filed October 22, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 22, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 22, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
