Do they?! How does that help fire safety?

Flames licking up the outside take longer to ignite the frame,
retarding fire spread.

Most fires are internal, where there's combustible material. You would
have thought a window on an external leaf would be better?

Inner leaf windows have been standard for this
reason for a very long time. Outer leaf windows tend to be found on
very old houses that predate this.

I haven't seen a house with a window on the inner leaf for a long time.
They generally have wide inner sills and adorn ornaments and the like.

Are you sure you're talking of the UK?

He's talking drivel.
Windows are to keep the weather out, as is the outer leaf.
Hence the window has to be linked/continuous with to the outer leaf.

Plastic windows are a fire hazard.
The plastic gives off highly toxic fumes in a fire.


Are all of your window frames wooden or Crittal steel then?
