Space-retainers (11) are formed onto the panel (1) on its fixing side. These pref. comprise two ribs or ledges etc., fitted to two opposite edges of the panel. Panels may consist of a base panel and a decorative panel, with intervening media for detachable connection, such as adhesive strips. Panels are easily laid, and decoration can be easily and inexpensively changed.</p> |
