Subfloor joint

A set of essentially identical subfloor panels comprising a joint configured to be glued, wherein the joint comprises a strip which protrudes from a first joint edge at an edge of a panel,

• wherein the joint comprises an element groove at an underside of an adjacent edge of an adjacent panel and adjacent a second joint edge of the adjacent edge,
• wherein the strip comprises an element which is configured to cooperate, in a joined position of the edge and the adjacent edge, with the element groove for positioning of the panel relative to the adjacent panel in a first horizontal direction and the first joint edge is configured to cooperate with the second joint edge for positioning of the panel relative to the adjacent panel in a second opposite horizontal direction,
• wherein the joint comprises a tongue at an outer part of the strip and a tongue groove below the element groove or a tongue below the element groove and a tongue groove at an outer part of the strip,
• wherein the tongue is configured to cooperate, in the joined position, with the tongue groove for positioning of the panel relative to the adjacent panel in a first vertical direction,
• wherein the joint is configured for a joining of the edge and the adjacent edge by a vertical motion of the edge relative to the adjacent edge,
• wherein a first space above the strip and between the element and the first joint edge is configured to be filled partly or completely with a glue before the edge and the adjacent edge are joined, and wherein the joint is configured such that during joining the glue is displaced in the joint and towards an upper surface of the panel and towards a lower surface of the panel, and
• wherein a flow resistance towards the lower surface is larger than a flow resistance towards the upper surface.
