SOLBORG sliding sash windows - Ideal for restaurants, cafés, etc.

We have sold our sliding sash windows for many years, mainly for villa projects in England, Scotland and Ireland, but also experience increasing interest from customers in Denmark, Germany and others who want a special English style.

In addition, a sliding sash window is suitable for places where you want to be able to open the window without having to take space inside or outside. Therefore, we also often sell the sliding sash window to restaurants, cafes and kiosks.


The SOLBORG sashes are made with internal glazing beads and external silicone sealants so that they  match the casement window design in Vrøgums CLASSIC product line, and can be combined with these  in the same architectural expression.

The windows can be delivered with single or double glazing and can be customized with very strong sound proof
