Vertical Sliding Secondary Glazing
Can the new rail line up with the original sash?
The measured opening and the chosen system determine how closely the internal division can follow it.

Vertical Sliding Secondary Glazing — planning the work
For vertical sliding secondary glazing, 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.
Do both inner panes open?
Establish which panels move and how they are cleaned before manufacture. Opening arrangements differ by product.
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.
