Horizontal Sliding Secondary Glazing
Sliding secondary panes add an inner glazed layer while keeping the existing external window in place.

Horizontal Sliding Secondary Glazing — position sliding tracks within the window reveal, with specification, handling and safe installation requirements agreed, with the surrounding frame, fittings and opening condition checked.
The track layout is measured around the original window divisions, handles and room-side obstructions. Panel travel and cleaning access should be understood before the system is ordered.
