Double Glazing system Simple Easy Fix (Peggylea EH26)

Secondary glazing system. Use your own glass or polycarbonate sheeting and fit plastic channel around it - mitre guage supplied for precise corners. Use neat plasitc toggle clips (see photo) to hold glass snugly to frame covering all leaky gaps. In the warm (ha!) turn toggles to release glass. I have used and still do this system very effectively on wooden sash and casement windows. Works a dream. Surpluss to requirements - several packs.
