PVC windows featuring GEALAN profiles deliver the perfect balance of energy efficiency (U-value 0.6-0.9 W/m²K) and affordability, providing 25-50 years of reliable service with minimal maintenance. Our triple-glazed PVC window systems reduce heating bills by up to 30% annually while ensuring exceptional sound insulation for your home.

Aluminium windows crafted with Yawal and Aliplast systems enable stunning floor-to-ceiling glazing with passive house performance (U-value from 0.5 W/m²K), maintaining their pristine appearance for over 50 years without maintenance. Panoramic aluminium windows featuring slim profiles and thermal breaks maximize glass area, allowing up to 20% more natural light than conventional designs.

Choosing the right window and door joinery is one of the most important decisions when building or renovating a house. PVC windows manufactured in the GEALAN system are characterized by excellent thermal insulation as standard (Uw coefficient 0.8-1.1 W/m²K) and an attractive purchase price. Aluminum windows manufactured in the Yawal and Aliplast systems, on the other hand, allow for the creation of impressive glazing with dimensions of up to 3m x 3m in a single sash, are distinguished by their exceptional mechanical strength, and require virtually no maintenance for decades of use. This makes modern aluminum joinery dominant in prestigious architectural projects and modern office construction.
Replacing old windows with energy-efficient windows brings measurable financial benefits. Traditional windows with a Uw coefficient of 2.8 W/m²K cause energy losses of around 280 kWh/m² per year. Our solutions with triple glazing and warm edge spacers, achieving a Uw heat transfer coefficient of 0.6-0.9, reduce these losses to just 60-90 kWh/m². For an average single-family home with 20 m² of window area, this translates into savings of 4400 kWh per year, which at current energy prices means approximately 800 $ less on heating bills.
Warm window installation using specialized vapor barrier tapes and installation foams additionally eliminates thermal bridges, increasing energy efficiency by another 10-15%.
Security is another key aspect when choosing windows. Our RC2 class burglar-proof windows equipped with MACO or Roto fittings effectively protect against burglary, withstanding a 3-minute break-in attempt using simple tools. For ground floors and detached houses, we particularly recommend RC2 class solutions with P4A safety glass, which, in combination with RC3 class aluminum exterior doors, create an effective protective barrier.
The Uf coefficient of profiles and the Ug coefficient of glass are only some of the parameters affecting the quality of windows – equally important are the sound insulation of windows (Rw 32-45 dB), the watertightness of windows in class 9A, which guarantees tightness during heavy rainfall, and the air permeability of windows in class 4, which prevents heat loss through leaks.
Our offer includes comprehensive solutions for every type of building. HST patio doors up to 6 meters wide open your home to the garden, PSK sliding doors save valuable interior space, and external roller shutters provide additional insulation in winter and effective protection from the sun in summer.
The portfolio is complemented by facade blinds, custom-made mosquito nets, elegant stone window sills, and functional interior and exterior window sills. For energy-efficient homes, we offer windows with triple glazing, which, despite their initial price being about 30% higher, pay for themselves after just 5-7 years of use in buildings larger than 150m². Window ventilators ensure constant air exchange without the need to open windows, which is particularly important in homes equipped with heat recovery systems.
We also carry out advanced architectural projects, including aluminum facades, winter gardens, and aluminum pergolas, which are a modern extension of living space. Custom-made aluminum panoramic windows and aluminum sliding patio doors allow you to create spaces full of light.
We work with architects and developers on projects in Poland and Central Europe, offering multi-colored windows for modern homes in the full RAL palette. Our technical advisors will carry out a free measurement and energy audit, helping you choose the optimal solutions – from energy-efficient windows up to 0.6 W/m²K to complete garage door systems.
