ABSTRACT
One of the success stories of the 1980s was the resurgence in popularity of the conservatory, based largely on special designs and systems of aluminium extrusions. Whereas the standard garden greenhouse is made of mill-finish aluminium, the standard conservatory mainly embodies white-painted aluminium. Detailing of design is facilitated through the ease of producing custom-made sections by extrusion and by the relative cheapness of making the required dies. One of the success stories of the 1980s was the resurgence in popularity of the conservatory, based largely on special designs and systems of aluminium extrusions. The strength of aluminium alloy is important in conservatory design, particularly for roof members where it is essential to have properly stressed sections that will withstand snow and wind loadings. On the domestic scene the ease of erection of the ‘add-on’ rooms coupled with freedom from involvement with planning permission has made conservatories an ideal way of providing an attractive house extension.
