To the basic advantages of the polycarbonate, allowing to speak about its uniqueness and difference, thus, from others amorphous and partially crystalise polymers, it is possible to carry the following:

• The High degree light passing
• Protection against ultra-violet radiation
• Excellent thermal insulation
• Extremely easy weight
• Ultrahigh crashworthiness
• High bearing ability
• Stability the atmospheric phenomena
• Fire safety
• The Opportunity of bending in a cold condition
• High chemical resistance
• Simplicity of assembly and installation
• The Prevention of formation of a condensate
• Good sound insulation
• The Long warranty period
• Rather low cost

1. A high degree light passing

Polycarbonates panels possess high light passing ability that is ideal for constructions where the maximal passage of light is required. For cellular polycarbonate this parameter depending on thickness of leaf curving from 83 up to 90 % (transparent sheets), that frequently exceeds light passing standard silicate glasses (some marks of polycarbonate are applied even to moulding automobile headlights).

Besides transparent panels, all manufacturers let out white panels with a different degree light passing: from translucent "disgraces" with coefficient light passing 50-70 % up to as much as possible sated white "sing" with coefficient 20-30 %, allowing to achieve optimum parameters for concrete application. Dark blue, turquoise, blue-green, green panels and "bronze" with coefficient light passing depending on thickness and structure of the panel of 25-45 % are issued also transparent toned.

All kinds of panels of cellular polycarbonate favorably disseminate light, creating uniform light exposure inside of premises.
