The TT series of tilt & turn windows is made of either softwood pine, or hardwoods such as meranti and oak, but have a modern, aesthetically-pleasing look and feel, thanks to a beautiful, rounded profile, which contributes to streamlined shapes.
Perfect quality and resistance to frame-warping are guaranteed by three-layer engineered wood, which is dried to a suitable level of moisture. Additionally, the lifespan of the joinery is prolonged thanks to its preservation and staining. Thresholds of frames and lower edges of wings are protected by aluminium drip profiles, the lines of which harmonize with the gentle contours of the entire window.
Preservation of the joinery is very simple and does not take longer than its cleaning.
