Is there any requirement for the 'glass' to be easily breakable so that
people can escape through windows if the bus overturns in an accident?

As far as I'm aware, only if it's a designated emergency exit, in which
case, there'll be a hammer nearby. Alternatively, you get a mounting
system which releases the window by pulling a ring, which loosens the
window in its frame so it can be pushed out.

As the vehicle in question doesn't appear to be a PCV but is a playbus
not licenced to carry passengers, other rules might apply, such as the
fire escape rules for buildings.

The only neg I could think of in using non standard replacement glass is
the _possibility_ that any requirement for safety glass can only met by
using kite marked product that indicates it is suitable for vehicular
use. Not saying it will be an issue, just flagging it as worth checking
with a tester before fitting. Using the plant glass replacement company
already linked to should avoid such difficulties.
