Fin for glazed fixed panel

[Taff]

Just had an email from window supplier. Can any one explain in lay mans terms! Re the fin.

email says pic attached 

Good morning Chris,

 

Reference the above, an internal fin reinforcement as below is required on the mullion of the large fixed frame (ref 20) due to the size and location. I’m highlighting this to you if you feel it is something your client will need to be aware of.

I believe it’s a stiffener, any thing in that profile will add strength and stiffness,

i would say you must have a large span.

So does this run the full height or is it just a piece on the top and bottom?

Think it’s 3.5m of top of my head

Email doesn't say if its a horizontal or vertical mullion. Better ask if not obvious. Probably full width or height accordingly.

I may be wrong but I thought a mullion was vertical and a transom was horizontal.

Spot on.

 

Imo they are referring to the vertical white rectangle which is the reinforcing fin strengthening the million against bowing. Drawing is a horizontal section I believe.

 

Nice, sharp edge to fall onto and headbutt at 6mm wide! If it has to be there I'd be asking for a 48.5 x 52mm clip on or similar "cover" at no extra cost and finished to suit.

 

Or...some split pipe lagging! ?
