Polycarbonate

Honeycomb polycarbonate

The honeycomb polycarbonate (structured, cellular-type) represents panels with the thickness of 4mm, 6mm, 8мм, 10 mm consisting of two plates of polycarbonate connected by longitudinal edges of rigidity. As a rule materials of bigger thickness (16mm, 25mm, 32mm, 35mm, 40mm) have a more difficult structure including 3 and more layers and strengthened by crossed edges of rigidity. Due to the presence of air layers the honeycomb polycarbonate turns out to be a very light, thermal and sound-proof material.
Even the most thin sheets of honeycomb polycarbonate (4mm) exceeds a simple glazing almost in 2 times according to the degree of a thermal protection. The sheets of 8mm are comparable by the thickness to a double-glazed window, the sheets of 16-25mm exceed the thermoisolation indicators of double-glazed windows with threefold glazing

Transparency

The optical transmission of transparent two-layers panels reaches 86 % (the high-quality glass has the same thing up to 98 %); and, the prevailing part of light rays passes in a dispersed way that is very important in plant growing. As a result the rigid ultra-violet radiation with the length of a wave up to 390 nanometers (nm), that is harmful for any human, plants and equipments, practically does not pass through the panel, and the transmission of useful rays is optimum. Besides, the honeycomb panels are opaque in relation to the infra-red radiation over 5000 nanometers, that, on the one hand, keeps the energy radiated by sources of heat indoors, and, on the other hand, limits influence of the infra-red radiation on people and plants from the outside.
The optical transmission of the panels practically does not decrease during the long-term operation outdoors.

Small weight

The panels of the honeycomb polycarbonate weigh in 10 times less than glass, and in 3 times less, than the acrylic of the same thickness and it allows to reduce expenses for the supporting frames, the transportation and the installation (it is possible to do it without use of any elevating mechanisms).
The small specific weight allows to project light frames with a considerable quantity of design possibilities. It has defined the basic range of use of the honeycomb polycarbonate, as material for the creation of winter gardens, greenhouses, transparent roofs, sheds and other architectural elements.

Shock strength

The polycarbonate is one of the strongest thermoplastic materials. Despite its lightness the polycarbonate is stronger than glass up to 250 times and more durable that acrylic panels in 10 times.
One of the advantages of the honeycomb polycarbonate is that panels do not fly to fragments during their destruction. The polycarbonate protects reliably from hail. Tests show, that a hailstone with the diameter of 47mm, flying with a speed of 25m/second, cannot punch the panel with the thickness of 16mm.

Fire safety

A distinctive characteristic of panels of the honeycomb polycarbonate is their ability to the slowed down ignition and a small issue of poisonous gases. The ignition of these sheets is much lower than one of the sheets of fiber glass or acrylic.

Operatingrange of temperatures

The honeycomb polycarbonate is firm to the most unfavorable climatic conditions. The panels have shown a high shock resistance and a safety of initial optical characteristics in a range of temperatures from-40°S to +120°С, and it allows to use them in any point of the globe.

Lifetime

Factories that produce the polycarbonate, provide a warranty for 10 years. It is a guarantee of the fact that it will keep the same physical characteristics and the appearance as at the moment of its purchase.
Therefore it can be used practically in all frames, both in temporary ones, and in solid ones. Proceeding from the experience, the lifetime of panels of the honeycomb polycarbonate as a covering and roofing material is not limited by the specified warranty period, and can exceed 25-30 years.
