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. Renovating 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.

If safety is important, you can improve the anti-burglary class of your home's windows up to RC3 by choosing high-quality PVC windows from profiles made in Europe. Modern smart solutions for window security are also possible - preventive alarm SmartGuard.

Our offer includes a wide profile palette and a large selection of colors and shapes. In addition to a few color variants, you will be able to choose the shape of the windows almost unlimitedly. The various mounting options of PVC windows will allow you to fulfill any customer's wishes both in new constructions and during home renovation, from standard solutions to exclusive solutions specifically for your home.

Save heating costs with new REHAU windows
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. The windows are most often one of the places in the house where there is the greatest heat loss.
A lot of valuable energy is lost through poorly insulated windows, therefore, when choosing windows, attention should be paid to their energy efficiency. Heat loss through windows will be affected by both the size of the windows and their quality. To save heat, it is recommended to choose multi-chamber PVC windows with the lowest possible window U-value (thermal conductivity coefficient), which retain heat well and are made of quality materials.
Installation of windows is no less important, after their installation the window openings must be properly insulated and properly sealed. Correct placement of windows in the window bay will allow efficient use of solar energy and reduce the use of artificial lighting.
What are the benefits of choosing energy efficient windows?
  • Reduced heat loss in houses
  • Saved heating costs
  • Reduced impact on climate and environment
  • Careful treatment of resources
  • Increased home value
