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 oak wood products are especially suitable for existing buildings or new construction projects. Oak wood is one of the oldest and most popular hardwood species in the world. This rather heavy wood is first-class furniture wood with high strength and stability. The medium brown to reddish gray wood of the oak will darken, leaving a noble impression. The fine, dense grain is highly textured and the pore grooves emphasize the wide wood rays.
