A front access means (1) for mounting ceiling, panelling and cladding boards comprises an elongate base strip (2) of a cross sectional shape which has a flange or flanges (4, 5) and a gripping formation or formations (6, 7), together with an elongate cover strip (8) again of a cross sectional shape which has a connecting formation or formations (9) adapted to co-act with the gripping formation (6, 7) for connection of the cover strip to the base strip. A tool is provided for removing cover strips if it is required to remove an installed board. The front access means is best used for all types of ceiling board installations, in particular with a new light weight ceiling board, made of double wall corrugated board from virgin liner and fluting, sealed with a special sealer on both sides and pre-coloured. This board is much lighter and a much better heat insulator than conventional boards. A saving of total installation cost, including the labour component, of between 40% and 50% is obtained, using the invention.
