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


Welcome to this Newsgroup Barry, which I see you access via GB instead of
direct, lots of knowledgeable people on here.
Toughened glass will not keep the heat in any more than normal glass it's
just safer as it breaks like an old windscreen into small square chunks
instead of sharp nasty shards.
To keep the heat in you will need to use a layer of bubble wrap inside the
glass or you could go for acrylic glazing instead of glass but that is
costly and has other drawbacks.
The necessity of keeping the warmth in depends on what you intend to grow,
so if you let us know that we could, maybe, be more helpful.
