The outer layer of a roof shows great variation dependent upon availability of material, and the nature of the supporting structure. Those types of roofing material which are commercially available range from natural products such as thatch and slate to commercially produced products such as tiles and polycarbonate sheeting. Roofing materials ...
These discs are produced by injection-molding polycarbonate into a mold cavity that has on one side a metal stamper containing a negative image of the disc data, while the other mold side is a mirrored surface. Typical products of sheet/film production include applications in advertisement (signs, displays, poster protection). [6]
Although single layer polycarbonate sheeting is more flexible than polycarbonate in twinwall configuration, it still retains significant advantages over alternative materials, including glass. A typical 6mm sheet has a density of 0.72 g/cm^2 [6] and a thermal insulation R value of 0.3 m^2°C/W, while allowing 80% of visible light pass through. [7]
Almost all plastics can be formed into a thin film. Some of the primary ones are: Polyethylene – The most common plastic film is made of one of the varieties of polyethylene: low-density polyethylene, medium-density polyethylene, high-density polyethylene, or linear low-density polyethylene.
The evolution of techniques towards "sandwich" glass composed of two glass sheets glued to a synthetic film improved mechanical resistance, safety, and allowed for larger glazed surfaces. The use of glass with a central metal framework (factory roof sheds), organic glass, resin as for polycarbonate sheets, widely used for veranda roofing due to ...
Kaynemaile is a chainmail fabric consisting of polycarbonate interlinked rings connected together by liquid-state assembly to form a flexible mesh sheet. It is made from polycarbonate and used in the architecture and design industry. [1] [2] It was invented by Kayne Horsham in 2004. [3]
The Journal of Plastic Film and Sheeting is a peer-reviewed scientific journal that covers the field of materials science, especially the development and processing of plastic film and sheeting. The editors-in-chief are John R. Wagner Jr. and James P. Harrington.
The most common materials used in modern greenhouses for walls and roofs are rigid plastic made of polycarbonate, plastic film made of polyethylene, or glass panes. [1] When the inside of a greenhouse is exposed to sunlight, the temperature increases, providing a sheltered environment for plants to grow even in cold weather.
