Sorpetaler special windows: our special wooden window designs

the sash window: like in the movies

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 to preserve a traditional look

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.

pivoting window: sophisticated pivot system for optimal ventilation

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.

windows for listed properties: preserve the charm of historic buildings

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.

energy-saving windows for special energy requirements

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.
