Enjoy the luxury of Glass Shutters, an innovative secondary glazing that preserves the character of your traditional sash windows.  As well as maintaining warmth, Glass Shutters can also reduce condensation.

The frameless hinged panels fit within the batten slips and are easily opened to allow access to the window.  By choosing an appropriate style, the panel divisions can be made to coincide with the glazing bars.  This minimizes the visual impact from inside while making the Glass Shutters virtually invisible from the outside.

To reduce condensation, the cavity between the Glass Shutters and the original glazing should be vented to the outside.  This can be achieved by installing a trickle ventilator in the top rail of the sash window.  Provided your room has some ventilation, this will allow cold dry air to enter and filter through the gap between the Glass Shutters and the window frame.  As it does, it will mix with the warm moist air in the room, reducing the moisture content in the vicinity of the window.

For safety, the glass panels must be toughened and for maximum warmth, low-emissivity glass should be used.  This has an invisible coating on the exterior face which allows radiation from the sun to pass through but reflects heat trying to leave the room.
