The first thing to do is to glaze a loggia (balcony). Warm PVC windows are used for this. Today, many specialized systems are represented on the Russian market, but it is better to stop the choice on time -tested firms. For example, plastic windows of the KVE brand (Germany) or Exprof (Russia). Produce these specialized systems in Russia under a license, part is delivered from Germany directly. Double -glazed window in window structures must be two -chamber. Its minimum thickness 32 mm. When placing an order for glazing, purchase at the same time expansion profiles. They will be needed for the installation of insulation and finishes, since on a glazed but not insulated loggia it will only be slightly warmer than on the street. Everything should be insulated: side walls, floor, ceiling, parapet.
