the sash window
Does your room need an opening window, but lack space – e.g. a bathroom? Or do you want a smart pass-through window between your kitchen and patio? The Sorpetaler vertical sash window is the ideal solution for these requirements. Patented and developed in-house, our sash windows are available in wood and wood-aluminium, with 68 mm or 78 mm frame thicknesses. Made individually to meet your requirements, they are suitable for use in new, old and listed buildings.
