Again a huge thank you to glass build for providing the 10 specially made triangular double glazing units I will use in my piece which are now in a very safe place in the studio.
The glass used in the double glazing units is 4mm thick, and there is a 10mm spacer between the 2 sheets of glass that make up each unit. This means that the over all depth of each triangle is about 19mm once the tape and mastic has been included to hold them together.
The angle bar used on the frame wass 20 x 2o mm so the fit of the glass units is flush in to the angle bar! ..diagrams and images to follow later this week if that was a bit confusing…images are so much easier.
