| Replacing
Sash Windows:
All windows must now be
installed to meet with building regulations.
Here are the following building regulations
which replacement sash windows much conform
to.
- Documents “F”
(Ventilation)
- Documents “B”
(Fire Escape)
- Documents “N”
(Safety)
Documents “F”
(Ventilation)
To comply with document
“F” all sash windows must
be fitted with a lockable night vent facility
which is standard on all our casement
opening vents.
Documents “N”
(Safety)
Most sash windows will require
toughened safety glass, as the glazing
will be lower than 800mm from the finished
floor level..
Documents “B”
(Fire Escape)
Most first floor sash
windows have been replaced with a top
over fix design with the transom half
way down the window to give a similar
look as the original sash window. Under
building regulations this is no longer
an acceptable means of escape. In order
to meet this building regulation there
are several options:
- Revert to the
original design
- Lower the height
of the transom to below 1100mm and the
top opening vent becomes a fire escape
- Install a fix
over an opening vent with a trickle
vent for high level background ventilation
- Re-design the
window to have two top hung opening
vents
