Made in Latvia


Perfect formability, absolute design freedom, optimal price-performance ratio - all this applies to windows and doors made of high quality PVC. We produce our profiles with a very special surface: High-Definition-Finishing.

This extremely smooth surface hardly allows dirt to settle and is easy to maintain. Maintenance of our windows and doors can be done quickly: once a year a few drops of household oil on the fittings and silicone on the seals.

PVC windows and doors provide a high level of comfort and excellent sound insulation. A high-quality sealing system in the window frame and sash not only takes care of sound insulation in your home, but will also protect it from strong winds and rain gases. Excellent thermal insulation will prevent warm air from escaping from the house during the cold months of the year. You can be sure that the windows will last a long time and their visual appearance will remain unchanged even after many years of use. Renovation with energy-efficient PVC windows will improve the thermal insulation of your home, even cutting your home heating costs in half in the long term.

Save heating costs with new REHAU doors
You cannot influence rising energy prices, but you can reduce your personal energy consumption. By building house or when renovating a house, it is important to minimize heat loss as much as possible, thereby reducing heating costs and saving money. It is the door that is most often one of the places in the home where there is the greatest heat loss.
A lot of valuable energy is lost through poorly insulated doors, therefore, when choosing a door, attention should be paid to its energy efficiency. Heat loss through the door will be affected by both the size of the door and its quality. To save heat, it is recommended to choose multi-chamber PVC doors with the lowest possible door U-value (thermal conductivity coefficient), which retain heat well and are made of quality materials.

What are the benefits of choosing an energy efficient door?
  • Reduced heat loss in houses
  • Saved heating costs
  • Reduced impact on climate and environment
  • Careful treatment of resources
  • Increased home value
