glass for a fanlight....

been asked to help out with a new fanlight (window above a door to let light in to internal corridor).

Stud wall so seems plain sailing - only - how thick glass should be put in? apparently there are no regs so "anything" is ok - 4mm?

Glass area will be about 29 inches wide by 18 inches tall...

To retain it I was thinking 2 "frames" of quadrant bead nailed on to the newly formed opening, and glass in between with putty/glazing tape?

Constructive comments welcome as always

TIA

There are Regs for internal and partitiion glazing.

I'd consider using a pane on the outside and inside of the room, so they appear more similar, avoids a dust-gathering shelf on the side without a pane, and improves sound insulation between the room and the passage.

It should be laminated in a fanlight, or failaing that, toughened as minimum
as should any glass in a door, or in any frame connected to a door (or even
within 300mm of it as pointed out last week) but that said, the house I'm in
now has all fanlights above upstairs internal doors and they've been in 70
years, as all other houses aqround here.
I don't think I've ever seen one of them broken, but again, I'm not sure of
the glass thickness.
I'd go with 6mm to be on the safe side, but laminated is preferred as it
could break when slammed, and being above head height, well, you can work
the rest out for yourself

Is it a house or a flat? If a house, are there more than two storeys?
If a flat, is the door a lobby to the stair, without a separate lobby
between the stairs and the flat entrance? If a flat is it above the
first floor, or is the travel distance to the front door more than 9m?

If the answer to any of the above is yes, then the glazing and frame
may need to be fire resisting.

Hi Hugo,

2 storey house.

Are there any requirements for glass thickness or toughened/laminated as some posters seem to think?

TIA

Any chance of quoting some context in your posts?

I can see the need for 'special' glass where it can be bashed - but a
fanlight? There's one above my front door which I'd guess is very old by
the house number painted on it (which looks the same as some others in the
street) so may even be Victorian, and that hasn't broken, despite many
years of the door being slammed.

I'd use as thick glass as possible to reduce noise.

Mmm thanks but "Only relevant to Wales" it says!?

and no mention of fanlights or domestic "over door" glass.

Where's that stated?

You'd think there would be regs if it was that likely to happen....

Hence the post...

son of a friend of mine suffered a burglary when access to the flat was
gained by smashing the fanlight over the front door. Perhaps toughened or
laminated glasss would have made access more difficult?

Might well have done. Not that they seem to stop cars being broken into.

Consider a patterned glass to give some privacy in the room.

I have patterned acrylic sheet above two internal doors to let light
into a stair well. I used the quadrant bead both sides to fix - no putty.

Not for glass more than 1500mm above the floor in doors or side panels
(fan lights are clearly above this height).
