Profile Match

new sash fits the existing window frame, maintaining a uniform look

Do you want to change a fixed sash to an opening one?
This is entirely possible, and there are several reasons why:

  • The original installation did not account for the need for an opening window, or was done to save costs

  • Fixed windows are harder to clean – often requiring a specialist

  • Fire safety or ventilation regulations require an opening window

  • The flow of fresh air into the room is insufficient

  • You want to keep the existing opening but make the window more functional

A fixed window can be replaced with an opening one in two versions – side-hinged or tilt-and-turn. The latter offers more ventilation options and helps maintain a stable indoor climate.


Important to know:

  • The window profile system and dimensions must match

  • Precise measurement with millimeter accuracy is required

  • When splitting the frame into opening and fixed parts, impost features must be considered

  • It is recommended to use the same type of fittings as on other windows

This work requires precision and experience – our skilled craftsmen will do it quickly, cleanly, and with a guarantee.
