The unit can be mounted within the staff beads of a sash window enabling the retention of working internal shutters.
An internal hidden mechanism provides spring-assisted opening for easy access.
The unit 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 glazing bars to ensure that your windows retain their period features without being compromised – 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 and provide you with a perfect finish, virtually invisible inside and out.
This style of secondary glazing can be produced to accommodate the individuality of your primary windows, and can be engineered to facilitate arch/bow tops and even curved-in-plan.
