Plastic windows

plastic windows

Plastic windows or PVC windows are made of Kömmerling (German manufacturer) plastic profiles and completed with Roto (German manufacturer) fittings.
Plastic windows have recently become very popular due to their advantages:

  • Low price. Plastic windows are significantly cheaper than wooden or aluminum windows.​
  • Very good thermal insulation properties. High-quality plastic windows prevent heat loss in the room.
  • Long service time.
  • Great variety of colors, including wood imitation.
  • Built-in ventilation systems that reduce humidity in the room and ensure fresh air circulation.
  • Easy care. Cleaning is limited to a damp cloth from time to time.
  • Fast production process. PVC windows are relatively simple to manufacture, so they can be produced faster than wood or aluminum windows.
  • Color fastness. Plastic windows do not lose color over time.

High-quality PVC profiles do not contain lead and are completely harmless to health.We manufacture windows from the following Kömmerling profiles made in Germany:
