Processing is the term used for any sort of work on basic glass.

We undertake the following processing to order:


Glass is cut in our works by CNC annealed glass cutting machine, CNC Laminated glass cutting machine, or by hand.

Hole cutting for large diameters.


Multi PVB Laminates, fire resistant glasses and some thick Float, are cut on a vertical glass saw.

Polishing - Straight

The edge of glass is flat polished and arrissed on straight line edgers.

Polishing - Shape

Shapes are polished on a band machine or by hand where necessary.

Bevelling - Straight and Mitreing

Bevels by machine, on the face of the glass, in widths up to 45mm depending on the thickness of the glass.

Mitres up to 45 degrees.

Bevelling - Shape

On 6mm or thicker, internal or external radii must exceed the radius of the peripheral wheel on our machine.

Small sizes on application.


With a range of tubular drills from 4mm to 65mm on a double or single head drill.

From 70mm to 350mm with a variable diameter drill.


With Ethylene Vinyl Acetate (EVA) laminating interlayer films or resin, all types of clear, patterned glass and multi laminate combinations.

Clear and coloured interlayers; colours on request.


All over or to a design from your stencil or one produced from our graphics computer and plotter.

Frequently Asked questions about Processing

What are the basic edge finishes to a piece of glass?

  1. Arrissed Edge - The sharp edges are machined, not a finished edge, suitable for glazing or handling purposes or to reduce the risk of thermal fracture in annealed glass.
  2. Smoothed Edge - The edge of the glass is machined flat and the edges arrissed but not polished.
  3. Polished Edge - The edge of the glass is machined flat, the edges arrissed and the edge is polished.
  4. Bevel - The face surface of the glass is ground way and polished to various widths and thickness at the edge.  Unless the thickness at the edge is specified, it will be to our normal setting.

What diameter hole can be put into a piece of glass?

Virtually any diameter of hole can be drilled or cut.  The internal finish to a hole is generally a smooth one.  In toughened glass there are limitations as to how close to the edge the holes can be positioned.

Can you polish or bevel shapes?

Shapes can be bevelled and polished. Internal radii must exceed the minimum radius for the type of machine the glass is being worked on.  Submit details of the shape required.

Can you cut a shape from a .dxf file emailed to you?

Yes.  We have CNC machines for glass cutting and processing.

Can stencils be cut for sandblasting designs onto glass?

Stencils can be cut from your drawing, after being entered into our graphics computer, a copy will need approving before being put in hand or from your computer generated file.

Can "cut outs" or "notches" for plug sockets or other items be incorporated in the glass?

Yes, normally in toughened glass to increase the strength of the finished piece so there are rules as to how close to the edge or corner they can be, submit a dimensioned drawing for approval.

What sort of glass can be used in a barrier or a balustrade?

BS6180 defines the type of glass depending on the type of framework and building it is used in.  Your Architect, Specifier or Building Control will specify the Uniformly Distributed Load (UDL) in kN/m² and/or the Point Load in kN.  On receipt the type of building, eg domestic or commercial and the loadings, we can make a recommendation as to the type of glass to be used.

Glass floors, is there a maximum area and special frame?

We have data for the appropriate thickness up to 1m².  Submit the UDL in kN/m² and Point Load in kN and advise if a domestic floor, dance floor, corridor, or stair tread, for our recommendations.

What sealants should be used (i.e. are compatible) with the Ethylene Vinyl Acetate (EVA) laminating interlayer films you use?

We use EVA films manufactured by Bridgestone for the bespoke laminations we undertake (floor panels, barriers and the like).

Bridgestone have produced compatibility charts (link opens in a new window) to show which sealants should be used with their EVA films.

We stock clear and diffused EVA films.

What is "Cracked Ice"?

An EVA or resin multi laminate where one of the glasses used is a toughened one which after laminating, is broken and gives a "crazed" appearance.  At the time of enquiring we need to know if the piece is four edge glazed, clear, or tinted, and any processing that may be necessary.

Mirrors, how do I determine the, thickness, edgework, number of holes and whether safety backing is required?

We have tables to help determine the thickness.  If the edge is exposed or tiled up to, the edge should be polished.  A mirror will normally hang on the screws put in first, so 4 or 6 holes in the right position with the correct fixings, will be sufficient.

What thickness should I use for a shelf?

Again, we have tables and can advise you.

Is there such a thing as, "One-way Mirror"?

Yes, 6.4mm Laminated One Way.  The glass has a grey body tint with a reflective surface coating.  The glass is installed with the surface coating facing the observed area.  The glass has low light transmittance and high reflectance.  When the glass is installed with a lighting ratio of 7:1, the dark side being the side where the observer is (the obeserver should also wear dark clothing), the reflection will look like a mirror to the observed.

What is the mirror with stripes on?

"Venetian Stripe Silvered" deceives the eye by reflecting light from the bands of silvered glass, but is obviously not a secret viewing mirror.

Safety or Foil Backing

A mirror can be safety backed with a white woven film to give impact resistance on one face to BS6206 Class Bo.  Glass with a white woven safety backing cannot be fixed with a mirror mastic or low modulus silicone.  The film is coated with a release agent to enable the roll to be unwound and consequently no manufacturer of safety backing has approved their film to be fixed with an adhesive and conversely no manufacturer of mastic or silicones has approved their products to be used with a safety backing.

A mirror can be backed with an aluminium foil; as such it does not have an impact resistance classification.  Foil protects the reflective surface of a mirror and as it has no release agent it can be fixed with mirror mastic or low modulus silicone; with this method the bottom edge of the glass must be supported to take the weight of the glass.

If desired a mirror can be fixed directly to the substrate with mirror mastic or low modulus silicone provided there is an ample covering to ensure, in the event of breakage, no large and dangerous pieces are able to break off and fall or cause injury.  Support along the bottom edge is essential.
