Frequently asked questions
What is a hidden sash?
The sash profile sits behind the frame when viewed from outside; only the frame is visible on the façade, and opening sashes look the same as fixed panes.
Can triple glazing be used?
Yes; the glazing range up to 42 mm supports triple glazing and insulated units with integral blinds.
