Wood-metal windows combine comfort, ease of care, ecological quality and individual color and design options. This fusion of raw materials leads to the fact that the look timeless will continue to be modern and popular in the future. The technical values here have been optimized to the maximum, creating a window that meets the highest standards. The color of the metal can be chosen according to your needs. We at Rosa Fenster GmbH manufacture the wooden windows at our premises in Busswil near Lyss. Our fir wood products are especially suitable for existing buildings or new construction projects. Fir wood is more resistant to moisture and are therefore more resistant to acids and bases. An advantage of fir is also that there can be no resin leakage. The fir does not have resin channels that would cause this.
