Polycarbonate panels

• Polycarbonate is a unique engineering thermoplastic which combines a high level of mechanical, optical, thermal and electrical properties. Multiwall polycarbonate features a proprietary surface treatment which provides almost total resistance against degradation caused by UV radiation in sunlight.
  

• The enclosure frames are fitted with 10mm cellular or 4mm solid polycarbonate panels. We use cellular polycarbonate with two or three walls (four walls by order). Triple-walled polycarbonate has around 9% better insulation properties than the double-walled material.

• The polycarbonate panels act like a greenhouse. Direct exposure to the suns rays or, on cloudy days, the effect of diffused rays war ms the air within the enclosure. At night or on cool, cloudy days the heat of the enclosed at mosphere is slowly lost.

• The external surface of the polycarbonate has a layer of high-quality UV absorber, which blocks harmful UV radiation and prevents discoloration, crumbling and weakening.

• There are six colours of transparent polycarbonate available: clear, green, light blue, blue, milky and brown.

• We also offer special transparent polycarbonate with a NO DROP (Bayer GmbH) or DRIPGUARD (GE Plastics Ltd.) layer, which stops water vapour from dripping from the roof of the enclosure; instead it simply runs down to the ground along the inner surface of the wall. NO DROP or DRIPGUARD polycarbonate is used especially on large enclosures.

• An innovation introduced in 2004 is the use of self-cleaning EASY CLEAN polycarbonate panels, with unique UV protection on both sides, made by GE Plastic Ltd. (LEXAN Thermoclear Easy Clean).

• LEXAN Thermoclear Easy Clean sheet features a special coating on the outside surface that provides self-cleaning properties. These Easy Clean properties wash away any dirt each time it rains! It reduces your cleaning costs and provides long term light transmission.

• 4mm thick solid polycarbonate panels (made by Palsund Ltd., United Kingdom) have much better optical properties than cellular polycarbonate. They can be used either throughout the structure or only in selected parts of the enclosure (for example, for the end walls or one chosen wall).

  Solid polycarbonate

  • Solid polycabonate has much better optical properties than cellular polycarbonate, but weaker thermal insulation properties.

  • The basic Oceanic and Riviera designs have side and end walls made of solid polycarbonate.

  • The solid polycarbonate wall of Oceanic and Riviera enclosures has two sharp angles.
