Manual

Select Your Options

Option 1 > Greenhouse Glass

Three types of glazing are available for your greenhouse. Choose from standard horticultural, long pane toughened or 6mm polycarbonate options which let you customise your greenhouse to suit your needs.

Glass diagram images below are for demonstration of the glazing styles and may differ depending on your chosen greenhouse model.

with Horticultural Glazing (70890)

Standard 3mm glass which consists mostly of 2ft by 2ft panes, overlapping each other with the use of clips to hold one above another. This type of glass is traditional and very economical but tends to shatter into shards when smashed, so isn't recommended if you have children or pets.

£722.00 RRP: £1,022.40
with Long Pane Toughened Glazing (70944)

Long pane Toughened glass is a lot stronger, and more durable than standard Horticultural glass. In the rare event of it shattering, it breaks into safer smaller pieces. It is also neater and needs less maintenance as no overlapping glass means there is no algae build up and no Z clips to fit.

As good as expected

Liked the look of this greenhouse, not least the price which I thought very competitive. The extras are well worth considering, the louvre is good at increasing air circulation and I've found the staging essential. Glad I bought this one.

Lots of Working Area

This Halls greenhouse gives you lots of working area for your money and that's why I bought it. The double doors make access in and out of the greenhouse so much easier - I don't think I would recommend a single door greenhouse now I've got double doors. I also ordered some staging and an automatic vent which means one of the windows opens and closes itself as the temperature rises and falls again. Make sure you sue gloves when putting it up, especially with the glass, which is obvious really. The basic frame is very simple to install, the most difficult thing is identifying which piece is which, but a lot of them are the same to be fair. Looks good when finished and with some plants inside.
