I am replacing some upstairs landing doorways, and they are a door
with a glass panel over, to let light into the landing. The glass
cannot be filled in without plunging the landing into darkness. I want
to make the doorways OK for a future loft conversion. They already
have rising-butt hinges, which will cope with the self-closing (when
oiled !). But I understand the glass panel over will also have to be
30mins fire-resistant. Each pane is about 800 x 500mm. What type of
glass would I need, and what would the cost be ? This must be a common
situation - what is the usual solution ?
Thanks.
Simon.
