For windows that do not require regular ventilation, or are only used during summer months, Storm’s Slimline system offers the ideal solution.
It can be mounted within the 'staff beads' of a sash window enabling the retention of working internal shutters, which is often a requirement of conservation officers.
This system can also be used on various styles of windows where it can be installed into the reveals or inset into the primary window. By adapting our Slimline unit we are able to face fix them to provide a solution for French doors and fanlights.
Our slim, lightweight framework can be powder-coated to any RAL or BS number to complement your existing decor and provide you with an aesthetically-pleasing result, which is almost invisible both internally and externally. This style of secondary glazing can be made to accommodate the idiosyncrasies of your primary windows and can be engineered to facilitate arch/bow tops, curved-in-plan, circular and many other quirky shapes. Our Slimline unit is held in place using our magnetic system and is easily removable for cleaning and maintenance purposes.
