Room dividers are made to enable one large room to be either used as one room or when closed as two separate rooms. This could be for noise reduction or heat saving properties. One of the most popular uses is for isolating a conservatory. Depending on other factors some councils require planning permission for conservatories if they contain heating and are without lockable doors between the main building and the proposed conservatory.
Simple room dividers could be just a a pair of doors operated by a pair of handles and a rebated latch. More complex door sets could be sets of doors that could bi-fold or slide or a combination of each. They can be lockable and draught sealed or simply pushed to open. Room dividers can be mounted either with or without tracks and can be mounted so that they lay flat against the wall when fully opened. Fanlights can be added to maximise the light and side panels that are either fixed or hinged may be added to fill a wide aperture.
