Some of the names of materials or terms used in Prior Canopies website might not mean much to you. Below is a list of these words and what they actually mean.
GRP – Glass Reinforced Plastic. Also known as fibreglass. This is a strong lightweight material, formed by reinforcing a plastic polymer matrix with tiny strands of glass. Used in our door canopies, particularly in the Senator and President ranges, as well as our bow and bay canopies and garden rooms. GRP is also used in many other applications, such as cars, boats, cladding and storage tanks.
uPVC or PVCu – Unplasticised Polyvinyl Chloride. Used in our windows and doors, modifiers and stabilisers are added to PVC, to make a rigid product which is ideal for the building industry. Apart from glazed products it is also used in cladding, plumbing and drainage products. PVCu and uPVC are exactly the same thing. In Britain we used to refer to it as uPVC, but closer integration with our European neighbours has led to increased use of the term PVCu.
Tapco Slate. A blend of dolomite limestone and polypropylene. Formed in multiple moulds, so each slate is unique. Tapco slates are lightweight, versatile, attractive and easy to cut. They will not shatter, crack, curl or fade. Tapco slate is used on both the Minster and Westwood canopies in the Emperor range.
High Density Vinyl Polymer – Polystyrene. Used to manufacture Prior Canopies shutters. A thermoplastic substance which comes in many forms. Solid polystyrene is used in the manufacture of cutlery, plastic models, CD cases etc. Foamed polystyrene is used as a packing material or to make drinking cups and has many other uses.
Acrylic. A term used for chemical compounds derived from acrylic acid. Our acrylic canopies use acrylic glass, a transparent thermoplastic. Other uses include aquariums, visors and aircraft windows.
Cantilever. A beam supported at one end only. The load is all carried to the supporting end. In our cantilever car ports this means the load is all carried to the wall. The design of the roof beams allow for large loads to be put on the roof without it distorting. Other examples of the use of cantilevers are aircraft wings and some bridges.
Gable. A triangular shape used in house construction – the triangular portion of the wall between the edges of a sloping roof. In our canopies a gable refers to a canopy with a flat vertical front and sloping sides.
Hip. A roof or canopy where all sides slope downwards and there is no vertical face (gable).
Pitch. Angle of a roof. Used to denote a roof that is not flat topped.
Soffit. The underside of any construction element. In canopies, the horizontal underside, or ceiling.
Fascia. In house construction the fasciaboard is the vertical element which caps the end of the rafters. In our canopies it refers to the vertical edge around the bottom of the canopy.
