Warm Window


Welcome to the world of warm windows – an energy-saving, innovative, and reliable solution!

Our plastic windows are an excellent choice for those aiming to save energy while ensuring a comfortable and secure living environment. These windows are particularly warm, safe, and durable, helping to reduce heating costs and meeting the highest standards of sound insulation and burglary prevention.

Utilizing advanced technologies, we manufacture new generation 6-chamber passive plastic windows from the S8000 IQ PLUS system with 83 mm wide profiles. The 6-chamber configuration and design of the warm window ensure excellent thermal and sound insulation properties, while the greater installation depth and stronger steel profiles provide stability and strength.

The U-value of our warm window is only 0.8 W/m²K, and using a new generation selective glass unit with a silver oxide layer, this value decreases to 0.5 W/m²K. This means our windows not only isolate heat effectively but also retain it inside, meeting the requirements of energy-efficient buildings.

Additionally, we prioritize eco-friendly materials – our windows are free from lead stabilizers, making them more durable, longer-lasting, and retaining their shine longer. This is an important step towards environmentally clean production and sustainable environmental protection.

Our new plastic window, with elegant classic lines and a wide selection of colors and wood-imitating patterns, will be a great addition to your home or business premises.

A warm window is not only an energy-saving, high-quality, and durable product but also a solution that ensures your comfort and safety. Trust the reliability and exceptional design of our windows!
