Translucent roof of glass and polycarbonate

Translucent roofs are one of the most effective solutions for natural lighting. Earlier build translucent roof it could only be made of glass. It was not the best option, because the glass is quite fragile and thermally conductive material. Now he offered an alternative. This - polycarbonate. Its advantages over the glass as follows.

• High resistance to shock loads.
• Low thermal conductivity.
• Low weight.
• Easy to install and transport.
  At the same time there is a lack of polycarbonate - flammability. In addition, a new polymer material, to which many distrust. In such cases it is better to use a conventional glass roof, but built on new technologies. The key of them - the widespread use of double-glazed windows. They are particularly recommended for residential, well as heat and sound quality on their height.
  
  Glazing roof calculated to withstand much greater mechanical loads than conventional window glass. For this reason, for the manufacture of insulating glass not applied PVC profile and an aluminum or steel frame. The use of aluminum more preferably, as of rainwater, he almost does not corrode. Inside the aluminum frame glass stones can any materials, such as wood.
  
  In addition to the strength of the roof glazing high demands on tightness. If conventional insulating glass sealant is used only one method - Fill the inner edge glass butyl sealant is required on the roof of rubber seals in every seam. Their pad allows for open frame roof.
  
  In the northern regions to maintain a transparent roof in a frozen state is not necessarily require heating cable. In order not to deal with the snow melting, you can increase the slope of the roof. The mansard roof this problem is solved quite simply. Glazing subjected to only the extreme rays having a large angle of inclination, and the central part of the roof ridge and is not glazed and coated with conventional roofing materials.
