    I have a flat which has a small hall which accesses out onto the building hallway. The wall is pretty much all glass and it is the wire stuff and frosted.

    I am upgrading the insulation/windows etc on the flat and want to improve this glass wall to be more energy efficient.

    So i intend on removing the glazing on the fixed panels and replacing with 100mm infill kingspan. I will then over board both sides with ply wood and a moulding.

    I will however keep 2 small windows higher up. This way i get more privacy and better insulation.,

    Can i get small double glazed units made up, but in a fire rated glass ? Is toughened glass ok to use ? Any idea on the cost. Likely to be 50x 60cm in size for each one.

    I will change the door to a solid one, but with glass in the upper half. This will need to be fire rated.

    If you need fire-rated glass, why doesn't this construction need to be fire-rated as well? Some strong cement board instead of ply for example?

    Sorry, I don't know about fire-rated glass. I expect window suppliers/fitters do.

    I imagine it will also need to be fire rated, but with wood i can treat that with a special paint. That bit is easy. The glass bit is harder to sort out. I will speak to my supplier about it tomorrow. Just thought i would see if anyone on here knows about this topic.

    Why not use the wired glass for the double glazed units. There should be no problem putting wired glass on either one side or both sigdes of the DG unit. If you want more light through then specify polished wired glass although last time I used this (many years ago) it was significantly more expensive than the normal wired glass - which is what you have looking at the photo.

    Yes you can, and we did and don't remember it being overly expensive.

    However, since it's internal between the hall and kitchen (above a sliding door) I've no idea why we bothered with a DG unit. I think for aesthetics but if so it was a waste of effort as I don't think you'd ever have noticed.

    Looks like i will use a fire door with the top section glazed in the wired glass. This will give me enough light and will be less work overall.
