The alternative to buying a window

The design window manufacturer SILBER also offers holistic solutions in the field of window renovations that can be individually adapted to customer requirements. The renovation system from SILBER leaves the old window frame – damage to the wall is avoided. After removing the window sash and center transom, the new wooden windows are pushed onto the old frame from the inside. With the assembly of the outer aluminum part, a new SILBER window was created – comfortably solved thanks to innovative SILBER technology.
