A uPVC conservatory may also be known as PVC, pvc-u, or a plastic conservatory.
The most used material in conservatory manufacture is uPVC or unplasticised polyvinyl chloride (ridged plastic), also referred to as vinyl in America. The general reason that uPVC is used today in 100,000 of applications including upvc conservatory manufacture, is because uPVC is a thermoplastic a substance that loses its shape when heated and then becomes ridged again as it cools. Heat shapes uPVC into countless useful forms, so is easy to produce uPVC conservatory extrusions, which forms the upvc conservatory on the right.
Where additional strength is required the uPVC is reinforced with aluminium or other metals e.g. an upvc conservatory roof, upvc conservatory frames or doors. In some non-structure areas the uPVC is strong enough to support its weight e.g. some window frames.
