Glass Partition Size Guide

Hints for working out the materials needed for your glass partition.

Please call us if you are unsure; we are happy to calculate materials for you.

To work out the number of toughened glass panels you need for an opening:

Width/905mm=A

A rounded down to a whole number x905=B

Width minus B minus 15mm =the amount of space you have left to fill with 450mm panels, 250mm panels and timber or a custom made panel. The additional 15mm is to give you a 10mm gap at either end of the partition which will be covered by u channel.

Which panel height?

Panels start at 2040mm, then 2090mm, 2140mm, etc. going up in 50mm increments until 2690mm. Ceilings higher than 2750mm can be built down with a bulkhead or 12mm custom glass will be needed. Choose the closest sized panel below the ceiling height but ensure that there is at least a 10mm gap.

Which U Channel?

Aim for 35mm top and side, 24mm bottom for the easiest fit. If you are building the opening to fit our panels, make the opening 30mm taller than the panel height you would like. This allows you to use 38mm u channel on the ceiling and 24mm channel on the floor and 'lift and drop' the panels into place. If you don't have a 30mm tolerance, you can slide the panels into place through the door opening or use clip and go u channel.

Ceiling Height	Top U	Bottom U	Sides
<10mm	Clip & Go	Clip & Go	Clip & Go
<20mm	24	24	24
<30mm	35	24	35
<40mm	50	24	50
<50mm	50	35	50
<60mm	50	50	50

What size Toughened Glass Door?

Hydraulic Doors need a clearance of 16-26mm. Ideally 22mm. So take the ceiling height minus the u channel and ensure that the clearance is 21mm+/-5mm and if it isn't, consider changing the ceiling u channel. Generally the door will be are 30mm shorter than the panels.

How much U channel?

Width/3000mm rounded UP to the nearest whole is the number of U channels for the ceiling u channel. The same applies to the floor but as you will most likely have a door gap of 910mm, you may need less channel for the floor. You will also need a u channel for each end of the partition to cover any gaps and give a good finish. To decide which u channel to use on the walls, aim for as narrow as possible. The guide below shows the smallest size possible for the gap you have left:

TOTAL SPACE LEFT AFTER JOINS AND GLASS	>10mm	>46mm	>70mm	>90mm	>120mm
WALL U CHANNEL SIZE	24mm	38mm	50mm	60mm	75mm

Gasket

You need twice the amount of the perimeter for the gasket. For speed just times the amount of U channel by 6 to ensure you have enough.
