Slimline vertical sliding (VS) secondary glazing.
Slimline framing system ideal for treating traditional sash windows. Operated with spring balances which support the weight of the sash in all positions.
Slimline vertical sliding (VS) secondary glazing unit. Contra-sliding panes provide access to the primary windows for cleaning and maintenance.
Sashes cannot be removed. A minimum frame gap of 75 mm is recommended.
Sashes slide within the frame so do not interfere with blinds or curtains. Twin brush seals ensure high sealing efficiency. All fixings are concealed within the frame, which may be linked to other frames with a colour-matched mullion/ transom section.
Will reduce heat loss by up to 50% using standard glass, and up to 65% with a thermally efficient glass (low emissivity).
Suitable for listed buildings where the primary glazing cannot be changed. It is a reversible adaptation, so generally accepted by heritage agencies.
