Yesterday, I collected the glass for the downstairs window on the front west side. I decided I would use the Toughened Glass approach, as I have done in the other small openings.
This is a larger opening about 35cm square, as shown here. So I ordered a 50cm Square piece 10mm thick that will be fixed to the internal stone wall with the Expanded Foam and supported by the Insulated PB as before.
I will install, two lengths of PB mounted horizontally, which will make the cutting of the hole for the opening easier. I have decided to see if I can get some strips of Oak, 6cm x 1cm to install and make a nice finish for the internal opening, once all is finished.
