Over many decades, we have built up outstanding technical expertise in producing special wooden window designs for new and old buildings. These include our unique sash window, timeless pivoting window, attractive muntin windows with narrow muntins for old buildings, and our strong and stable lift and slide doors for large facade openings. All of our special window designs are available in wood and wood-aluminium.
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.
Muntin windows are ideal for refurbishment projects in older buildings, and the smart choice for developers who want to evoke the classic charm of a heritage property in a new-build. Wooden muntin windows from Sorpetaler are available with actual separate panes or with false muntins. For special requirements we offer extra-small XS muntins that are just 18 mm wide.
Sorpetaler wooden or wood-aluminium pivoting windows are the ideal solution when you want a large single-pane window that can be opened for ventilation. The sash on this window pivots centrally around a horizontal axis for easy ventilation and cleaning. Sorpetaler pivoting windows are available in widths of up to 2.80 m with 68 mm or 78 mm profile thicknesses.
Complying with strict regulations is just part of the challenge of refurbishing a listed building. It takes a lot of passion and dedication to restore the building to its historic splendour. We can support you in these projects with our decades of experience in renovating older properties and our special wooden window designs for listed buildings.
Wood is the ideal frame material for houses with stringent energy requirements, because wood naturally offers the best thermal insulation values. Our wooden energy-saving windows with triple glazing are true champions for energy refurbishment in existing buildings and for energy-efficient new-builds.
We can provide you with specific technical information and current values (U values, sound insulation values etc.) for our special windows on request. By e-mail, over the phone, or in person, our staff will provide you with a detailed consultation and can tell you everything you need to know about our special designs such as our sash windows, muntin windows, and energy-saving windows.
