Greenhouse Glazing options
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 |

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. -- Regards Bob Hobden |

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 -- Does anybody else find that bubble wrap is a real pain to install? For my 7' x 7' greenhouse it takes a day's work every second year, and the bubble wrap, which I buy in huge rolls, never overlaps enough, (just 1 cm wider would do), so, as well as the plastic clips, I have to use yards/metres of Duck Tape to get around the angles where the roof meets the walls and where the edges of the bubble wrap don't quite meet. *The clips work fine but there are bits of the greenhouse where they can't be used. *There must be a better way. *Can one buy the sort of double-glazed skin that the Eden Project uses, I wonder. someone You can buy clear tape that is used on Polytunnels from good Horticultural suppliers. It is very tough, sticky and expensive. You shouldnt have to replace the bubble wrap every two years. Mine lasts far longer than that. I did use some bubble wrap that is used for packaging and that became brittle after two years. Try Horticultural Bubble Wrap which has more UV resistance? More expensive but you gets what you pay for. |

Mind you, I'm in the northeastern American colonies, and winters are a bit colder, assuming I want to at least grow hardy greens year round. I'm currently using a cheapo tubing frame/plastic cover house, perhaps 8 by 6 feet, and the R-factor is, if anything, negative! There's a bok choi hanging on somehow, but not growing at this point.

I'll have a look for the horticultural kind next time I change the bubble wrap, and also for the horticultural tape. It would be worth it if I didn't have to replace it so frequently. I'm green with envy at Gary Woods' option of using double or triple polycarbonate glazing, AFAIK it doesn't seem to come with the standard purchased greenhouse. someone |
