postless corner window

patjack

Hi all,

Just to satisfy my own curiosity, but how are postless corner windows supported?

Finding it difficult to come across info regarding how these are supported.

I am assuming a steel frame, but still I wonder about the weight at the top of the corner on the steel.

Anyone know?

The steel needs to be large enough to take the cantilevered load of the corner and also will need to be held on the outer extremities either by weight ie structure above or by a steel structure, either way this would require engineering input and design consideration. Alternatively often above the these postless corners would be a lightweight timber structure rather than heavy masonry work.

Thermal bridging is finally becoming a consideration in their detailing, however this can't be left to window manufacture or engineer in my experience

I'm an engineer and spent half an hour yesterday trying to exain to a client why they can't have their corner window support post in line with their windows. I don't think it's fair to deride an entire profession like that, engineers by their nature should have acute understanding of technical details. Believe me, there are plenty of people of all professions in the construction sector who aren't as versed as they should be in things like this.

At least the typical engineer won’t still insist on concealing the structural support within the line of the window at a corner even after it's pointed out to them that thermal bridging will be a problem.
