7.13 COLONIAL/MUNTIN BARS
Muntin bars are used to simulate colonial style window framing hence the name colonial bars. They look similar to colonial style windows. The IGU is manufactured with bars as part of the unit.
Muntin bars are used to cut down the cost and work involved in glazing
small units to each colonial style
opening by utilising an IGU of the overall size broken up by internal (installed within the airspace) or externally applied metal bars. There are various styles available including Spacer Formed Colonial, Euro Colonial and Kiwi Colonial. Contact Metro GlassTech for more information.
7.14 Retrofit IGU Adaptor
A range of special aluminium extrusions and beads are available to convert single glazed windows to suit Insulating Glass Units. The adaptor systems are available for timber and aluminum joinery. The actual method used depends on the type of existing joinery and a full measure and quote service is available.
7.15 Blinds Inside
Blinds Inside give you shade within the two panes of your IGU. The benefits are no dusting, no wind rattle, no little hands or pets caught up in the blinds. The blinds are operated in the normal way, pull them up or down or twist the slats to control sun glare.
The following options are available:
- Pleated Blinds (14mm)
- Venetian Blind (16mm)
Colours available are White, Cream, Off White, Grey and Silver.
