# Frameless Glass Panels and Doors Sizing and Installation Guide

The information that follows will allow you to make an informed decision about buying glass panels and will provide you with a basic guide to the installation process.

Glass partitioning is a quick, neat and cost effective method of dividing space in offices, home and venues. Some great benefits of using glass partitioning to divide a space are:

• Standard panels are 10mm thick, so you lose minimal overall space.
• Glass maintains the open feel, and does not block natural light.
• Provides great soundproofing.
• Quick, inexpensive and relatively easy to install.

1.        Determine area for glass panel installation

# 1.        Determine area for glass panel installation

## 1.1.     Measure the complete opening from wall to wall in millimeters, ignoring any skirting or trim on the walls.

For a boxed meeting room (see image) mark out where you want the wall to finish and measure from this point to the wall for each side.

This will give you the total width (x) measurement.

## 1.2.     Measure the distance from floor to ceiling in millimeters, again ignoring any skirting or trim.

This will give you the height (y) measurement.

# 2.     Calculate height, width and the number of glass panels required

## 2.1.   How to find the ideal height for your glass panels

To determine the height of the panels you require, subtract 30mm from your initial height measurement for the U-channel (see explanation under U-channel: Section 3) and find the suppliers most appropriate matching height.

Example: height = 2520mm - 30mm (U-channel) = 2490mm
Panel size required = 2490mm

London Glass Partitions stock standard glass panels of the following heights:
• 2690mm & 2640mm
• 2590mm & 2540mm
• 2490mm & 2440mm
• 2390mm & 2340mm
• 2290mm & 2240mm
• 2190mm & 2140mm
• 2090mm & 2040mm

If your height measurement is 30mm-60mm from a match, you may be able to bridge the gap by using taller U-channel, or by fixing a painted timber baton to the ceiling or floor. For larger gaps, you may wish to consider building a bulkhead along the ceiling or a raised platform on the floor to reduce the height to an appropriate measurement.

Example: height = 2560mm - 30mm (U-channel) = 2530mm
Install 40mm timber baton along ceiling to reduce height =
2530mm - 40mm
Panel size required 2490mm

It is also possible to have glass panels custom cut to measure, however having glass custom cut will mean greater expense and a longer delivery period.

## 2.2.   Determining the height of your glass door

The glass door must be 25mm shorter than the glass panels to ensure that it fits into place and is able to open and close without obstruction.

London Glass Partitions stock matching door sizes for each of the glass panel sizes, for a full list of currently available door sizes please see http://www.ebay.co.uk/itm/Frameless-Glass-Door-Full-height-10mm-toughened-glass-door-all-fittings-include-/181345681616?pt=UK_Home_Garden_Doors_LE&var=&hash=item6fd709c0a0.

Example: 2690mm panel height will match 2665mm door height.

Again, you may also have doors custom cut to measure, though this will incur greater expense and a longer wait for delivery.

## 2.3.   Determining the correct number and width of panels to order

Full width glass panels are 900mm, however you should include a 5mm gap between each panel in your calculations, this space between each panel is filled with silicon and this greatly improves the strength and soundproofing of the glass. An extra 5-10mm should be allowed where a panel is to be joined to an existing wall using U-channel.

Example: width = 3000mm
2 joins to U-channel on existing walls = 3000mm – 10mm
number of full width panels = 2990mm / 905mm = 3.304

When the calculation for the number of full width panels is not a whole number (as in the example above) you can find the remaining gap by multiplying the number of full width panels (in this example 3) by 905mm and subtracting this total from the adjusted width, please refer to the example below.

Example: Number of full width panels = 3
3 x 905mm = 2715mm
Remaining gap = (adjusted width) 2990mm – 2715mm
= 275mm

London Glass Partitions also stock 450mm and 250mm width panels in all the listed heights, so in the above example a 250mm panel could be used to fill the remaining space in the wall.

## 2.4.   Adjusting the width of the space

To fill this space in your glass wall, you may wish to consider the following options:

### 2.4.1.    MORE than 100mm

1. Examine the various sizes of glass panels available and use a smaller size to fill to the gap. London Glass Partitions have 900mm, 450mm and 250mm panels available in all listed heights, please visit  http://www.ebay.co.uk/itm/Frameless-Glass-Panels-Full-height-10mm-glass-partitions-offices-and-homes-/181345645953?pt=LH_DefaultDomain_3&var=&hash=item6fd709a669 for a full list of available panel sizes.
2. Adjusting the size of the opening by building the wall in at one or both ends so that it fits an exact number of panels.
3. Having one or a number of panels custom cut to measure may be an option, though this will result in greater expense and a longer waiting period for delivery of your product.

### 2.4.2.    LESS than 100mm

1. You may be able to eliminate the gap by using a larger U-channel (50mm rather than 24mm) on the wall.
2. You may also consider running timber baton up the wall (cut to the appropriate size to eliminate the gap) and then fixing the U-channel to this baton.

# 3.     Installing glass panels

## 3.1.   Mark where the U-channel is to be positioned on the floor and ceiling

1. Use a straight edge and level, or plumb-line to check these two markings match exactly – this will ensure your wall is perfectly straight.
2. Cut U-channel to size using an angle grinder (if necessary), and remove any U-channel from the doorway.
3. Secure U-channel to the floor, ceiling and walls using flat head screws.

## 3.2.   Lift glass panels into place

1. Lift fully up into the ceiling U-channel.
2. Gently position bottom into line with the floor U-channel and ease the panel down into it, so that the panel stands with both top and bottom covered by the respective U-channels.

## 3.3.   Position the panels horizontally

1. Panels against the wall sit in the wall U-channel.
2. A 5mm gap should be left between each panel (this will be filled with silicon later to improve the strength, rigidity and soundproofing of the glass).
3. Check the space left for the door is correct – if it is out by under 20mm, you can adjust the panels to be hard into or up to 14mm off the wall, whilst still sitting comfortably in the wall U-channel.

## 3.4.   Insert rubber gasket to hold the glass securely in place

1. Rubber gasket must be run down either side of the U-channel (for each 1m of U-channel, 2m of rubber gasket is required).
2. This holds the glass securely in place and ensures a high-quality finish.

# 4.     Installing a glass door

NB: as previously stated in 2.2 the door must be 25mm shorter than the glass panels.

1. Check that the U-channel has been effectively removed from the doorway and that no part of it will obstruct the opening or closing of the door.
2. The glass door is mounted on a floor spring, which is encased in a metal box that must be sunk 6-8cm into the floor. This spring controls the motion of the door, and allows the door to be held open at 90 degrees.
3. Hollow out space in the floor and insert the floor box.
4. Fix two metal patches to the top and bottom corners of the hinge side.
5. The bottom metal patch allows the glass door to be slotted directly onto the floor spring once it is mounted in the floor.
6. The top metal patch allows the glass door to be slotted directly to the door pivot point attached into the ceiling or U-channel.
7. Lift the door into place and secure ceiling and floor hinges.

# 5.     Final check and silicon application

1. Perform a final check to ensure that the U-channel and rubber gasket is holding all perimeter panels securely, and that the door is positioned correctly.
2. Using silicon, fill the 5mm gap that has been left between each of the panels, scraping away any excess to ensure a neat, professional finish.
