A friend is about to built a hybrid of all three elements of a
Greenhouse/Glasshouse/Conservatory.
I can not quite understand the subtle differences between the three.
His architect is asking for glazing specifications.
Is Horticultural glass still used for anything or has H&S banned it?
Polycarbonate is out for fire reasons.
Would safety glass allow all the benefits of Horticultural glass without
the inherent problems?

What is its purpose?
