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?

http://en.wikipedia.org/wiki/Greenhouse
A greenhouse (also called a glasshouse or hothouse) is a building where plants
are cultivated. A greenhouse is built of glass or plastic; it heats up because
the sun's incoming electromagnetic radiation warms plants, soil, and other
things inside the building. Air warmed by the heat from hot interior surfaces is
retained in the building by the roof and wall.

A conservatory is a glass and metal structure traditionally found in the gardens
of large houses. Modern versions are smaller, can be made of PVC and are often
added to houses for home improvement purposes. Conservatories can be both
greenhouses and recreational spaces. The modern domestic conservatory is used as
an extra room rather than for horticulture.

IMO green/glasshouses are mostly for garden and plant freaks

Conservatories are often extra living space (sometimes with plants in them)
