Hi all,

New to this site and must say it's great.I am in the process of buying
a greenhouse and wondering whats the difference between horticulture
glass and toughened glass.Where the greenhouse will be located will be
exposed to winds until the garden becomes a bit more mature.Is it
better to go for toughened glass for keeping the greenhouse warmer
during the winter months?The toughnened glass is £200 extra.Any advice
welcome on this

Thanks

Barry





Toughned glass is stronger and safer but for the same thickness has no
better heat retaining propeties than standard horticultural glass (which
is normally 3mm thick as compared with the minimum for small house
windows of 4mm) AS Bob has said bubble wrap is the stuff to
insulate with the plastic clips you use to put it up are cheap and
reusable. Since the glass forms the main strength of a small greenhouse
if you are in a windy or exposed place the toughned glass would be better
(also better where children and pets are concerned) Having said all that
I use 3mm horticultral glass in all my greenhouses and so far all animals
and children have resisted the urge to throw them selves through! and I
do not get too much wind damage maybe 4 panes a year across 6 greenhouses
