The unit can be mounted within the staff beads of a sash window enabling the retention of working internal shutters.
It is held in place using our magnetic system and is easily removable for cleaning and maintenance purposes.
All secondary glazing sight lines will be matched up with your existing mullions to ensure that your windows retain their period features without being hindered by secondary glazing – a priority when preserving the character of your historic property whilst improving the thermal efficiency.
Our slim, lightweight framework can be
powder-coated to any RAL, BS number or wood
effect finish to complement your existing decor.
The end result is a virtually invisible glazing which can hardly be seen inside the building, or from outside.
This style of secondary glazing can be made to mirror the characteristics of your primary windows, engineered for arch/bow tops and even curved-in-plan.
