The Glazing page
outlines the different options:-
- Horticultural 3mm glass.
- Toughened 4mm safety glass.
- SAN Safety glazing.
Be careful, all glass is dangerous and horticultural glass in particular.
It is advisable to use gloves when handling glass.
It is best to glaze the greenhouse on a day when the wind is low.
Don't leave the greenhouse partially glazed overnight as any wind could cause
serious damage
