Secondary Glazing for Sash Windows
Does the old sash normally stay in position?
This approach normally aims to keep the original window. Any existing faults in that window still need attention.

Secondary Glazing for Sash Windows — planning the work
For secondary glazing for sash windows, frame position, opening access and the relationship to the original window affect the design. Agree panel operation and installation details after measuring the opening.
More questions
about this service.
Will internal shutters still open?
Include the shutters' full travel and folded position in the survey so they clear the secondary frame.
How is the quotation worked out?
Include any primary-window repair or relocation of fittings as separate agreed items. The secondary system, opening arrangement, pane specification, dimensions and fixing surface affect price.
Does the original window need its own condition check?
An inner layer does not repair decay, broken glass or faulty hardware in the retained window; those issues must be identified independently.
What should be covered at handover?
Check panel movement, fit, seals and cleaning access.
