PVC MIROX windows - advantages worth knowing

Any PVC window made of polyvinyl chloride is growing in popularity because of the many advantages that characterize the material. It is not without reason that both private customers, such as those in the process of thermal modernization of their homes, and businessmen who use them to close openings in the walls of factories, warehouses or workplaces, reach for them. This is not a work of chance – PVC MIROX windows have characteristics in line with the expectations of modern buyers, and their most interesting advantages are:

  • Thermal insulation – Our PVC windows are characterized by excellent thermal insulation, which means that they keep the building interior warm in winter and cool during the summer. The optimal heat transfer coefficient of PVC windows means a lot of energy savings and a reduction in heating or air conditioning costs.
  • Sound insulation – PVC windows are also effective in reducing noise from outside, which improves indoor comfort. Good soundproofing can be especially important for homes near high traffic areas or next to other similarly noisy places.
  • Low maintenance requirements – PVC windows are resistant to atmospheric conditions such as rain, wind and sun, making them low-maintenance. They do not need to be painted or varnished, and regular cleaning is all that is needed to keep them in good condition.
  • Long-term durability – PVC is a material that is resistant to corrosion, decay and the harmful effects of microorganisms. As a result, PVC windows retain their properties for many years without visible signs of aging.
  • Aesthetic design – PVC windows are available in a variety of colors, styles and designs, making it easy to match their visual side to the appearance of the building and individual aesthetic preferences They can imitate the look of wood or have a modern, minimalist design.
  • Energy efficiency – thanks to thermal insulation, PVC windows contribute to the energy efficiency of the building. This can have a positive impact on a building’s energy rating and potentially lower energy bills.
  • Availability of different variants – plastic windows are available in different types, such as side-opening, tilt or sliding. This allows you to choose the right solutions depending on the function of the room and your preferences.

Our PVC windows with a low heat transfer coefficient are a solid choice for those looking for durable, aesthetically pleasing and energy-efficient solutions for their homes or commercial buildings. With advantages, they can significantly improve the quality of life and energy efficiency of a building. There is a reason why our plastic roof windows can be considered a good choice in their price class.

Parameters of plastic windows of our production based on the model ID 8000

Each PVC window has been refined to the smallest possible detail, and this can be perfectly seen, among other things, in the ID 8000 luxury line, and in fact in Aluplast’s innovative profile system. The system consists of 6 chambers, was designed in Germany, and has an installation width of 85 mm. Thanks to this solution, a significant improvement in the thermal insulation index of 30% compared to standard windows has been achieved. This ratio, called the Uw coefficient, is now 0.76 W/m²K.

The innovative design of this profile system ensures that optimal thermal insulation is maintained. In addition, the profile reinforcement was made of galvanized steel, with carefully selected geometry and thickness (minimum 1.25 mm, and 2 mm for colored profiles). This reinforcement ensures rigidity, proper operation and maintenance of the original shape of the windows.

There is an option to use a warm frame with thermal insulation properties, which counteracts the deposition of water vapor on the panes, and allows energy savings of up to 10%.. There are a variety of colors to choose from, including soft gray, deep gray, classic white, elegant black, warm brown and intense dark brown.

Winkhaus activPilot hardware is equipped with a number of features that guarantee excellent window tightness. As standard, they have an anti-theft mechanism that minimizes the risk of burglary.
