Window fitting

Curious Geroge

I'm looking for some information on the correct manner in which large windows are fitted.

I have one very large window at the front of my house. Its 5.3m high x 3.4 wide. The window is made up of 9 sections and I wondered what is the correct process for butt joining each of the 9 sections. I can see these are bolted together but is it silicon that is used between these to stop air flowing through the window or a tape that would be used? The reason I ask is that I can see light through mine so there is a major problem that nothing was used in mine.

Mine are timber aluclad so its just butted together; nothing like the picture. I'll add a pic later on.

There should definitely be ‘something’ (apart from daylight) between the frames. Either a spline (usually timber) or better still, parallel epdm gaskets. Given the size of your window there should probably also be some reinforcement to hold all those frames together apart from a few screws and a dollop of silicone.
Do you have access to the manufacturer’s standard coupling detail ? My guess is it will show one of the above. You can then go back to them and ask why the as-built installation is at variance (non-compliant) and take it from there.

Looks like numerous bits are ‘missing’. No great surprise.
