We are the best not by chance. For us, the production of wooden windows is a particularly responsible job. We understand that quality, aesthetics and energy efficiency are the most important criteria for many people, so we invest a lot in this. Our experts are constantly improving window systems, looking for ways to meet the needs of every customer in the company, and offering practical solutions. A year ago, we were the first to offer an extremely warm Doleta Retro 110 window with a heat transfer coefficient of only 0.51 W/m2k. Doleta exports its products to almost 20 countries around the world, including Great Britain, Japan, the USA, New Zealand and Russia.
