Measuring Up Walkthrough.

Glazing Information For DIY Purposes

 

Measuring Up Your Glass

In the glass trade we use the following terminology and criteria for measuring glass. The first being a TIGHT SIZE this is obtained by measuring from wood to wood on your window or door. The second being a GLAZING SIZE which you obtain by knocking off 4mm to 6mm tolerance from the tight size. We recommend allowing 4mm tolerance on small squares up to 250mmx300mm, any sizes above this we would allow 5mm-6mm tolerance. Please note these guides are based on standard 12mm rebates/beading! If your rebates/beading are smaller you will have to make special tolerances. When ordering the glass you must state the GLAZING SIZE on your order.

Double Glazing


There are lots of different options for double glazing to chose from depending on the customers requirements.

The customer is to inform us-
* What thickness unit they require.
* What Spacer Bar they wish to use.
* If the unit is to be Gas Filled
* What type of glass they wish to use (example low e)

If you require more information on Double Glazed Units, please visit our Double Glazed Page.
 

How To Make Glass Rubbings


Often when customers want a design copied of some brilliant cutting we ask that you take a rubbing of the glass. This saves you having to send a box of broken glass to us, but instead just putting the glass rubbing in an envelope and posting it to us, please remember when sending us a glass rubbing to put your name & e-mail on it so we can distinguish you from our other clients.


How To Make Templates Of Shaped Glass


When your glass is shaped it can be a bit tricky to interpret, so instead we ask that you make a template of the glass. Templates are the easiest way for us to cut your shaped glass. We have made an instructional video below in order to help you with this process. When sending in a template please ensure your name & e-mail are on the template so we can distinguish you from our other clients.
