Horizontal Sliding Secondary Glazing
Will the outer window remain accessible?
Plan secondary-panel travel so the original catches and opening sections remain reachable. Confirm this during the survey.

Horizontal Sliding Secondary Glazing — planning the work
For horizontal 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.
How does this differ from a sealed double-glazed unit?
It is a separate internal window with a space between it and the retained primary glazing.
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.
