DOOR & GLASS THICKNESS
Lo-FP is now available in two profiles to suit standard 6mm glass (Profiles AA1), and 22-25mm double glazed units (profiles BB1) on standard 44mm thick doors. Using one A profile and one B profile (profiles AB1) suits 16mm glass on 44mm thick doors, and 7mm glass on 35mm thick doors. Unlike the Slimport designs (on pages 88-91) which fix through the bevel and have two different halves, Lo-FP portholes consist of two similar halves which fix through the flat face of the porthole. This means the glazing pocket will increase in direct proportion to the door thickness. The simplest way to think about it is that if you add or deduct 10mm to the door thickness, you also add or deduct 10mm to the glazing pocket. All that will be required is longer or shorter screws for fixing purposes.
Smooth round contour of low profile frame style gives a unique design to any setting.
Fire tested to 4 hours on steel doors and 1 hour on timber doors when used with Zero FS2002 intumescent glazing tape and FS4004 aperture liner (on timber doors) with suitable glass shown on page 95. FS9009 "ceramic type" tape also suitable for use on fire rated steel doors.
