Polycarbonates received their name because they are polymers containing carbonate groups. The main polycarbonate material, is produced by the reaction of bisphenol A (BPA) and phosgene.

A Polycarbonate Sheet, is polycarbonate material that has been formed into standard sheet dimensions, used for various building, engineering, construction or DIY purposes.

Polycarbonate Plastic, is the same thermoplastic material, extruded into sheets, rolls or pellets and offers manufacturers and designers opportunities to design with freedom, aesthetics enhancements and cost reductions.

Polycarbonate is a thermoplastic polymer containing carbonate groups in their chemical structures. Polycarbonates used in engineering are strong, tough materials, and some grades are optically transparent.

A skylight (sometimes called a rooflight), is a light-transmitting structure that forms all or part of, the roof space of a building for daylighting purposes. Skylighting types include roof windows, unit skylights, tubular daylighting devices (TDDs), sloped glazing, and custom skylights.

Skylight Cladding, refers to a type of translucent external barrier, applied to roofing, which both protects and provides the roof with additional performance benefits.

A Cladding System, comprises all the components needed, to create a full and complete solution - including framing elements and fixings. This system, then creates a the 2nd skin, which entirely encloses and protects the wall/barrier underneath.

Cladding types, can be made of any of a wide range of materials including wood, metal, brick, vinyl, thermalplastic polymers and composite materials that can include aluminium, wood, blends of cement and recycled polystyrene, wheat/rice straw fibres.

Cladding, is the application of one material over another, to provide an additional skin or layer. In construction, cladding is used to provide a degree of thermal insulation and weather resistance, and to improve the appearance of buildings.

A full rainscreen cladding system, is a form of double-wall construction that uses an outer layer to keep out the rain, and an inner layer to provide thermal insulation, prevent excessive air leakage and carry wind loading. The outer layer behaves like a skin, and in so doing, reduces energy losses.
