How To Install A Halls Greenhouse

Select Your Options

Customisation > Glazing

with Long Pane Toughened Glazing

with Long Pane Toughened Glazing (70944)

Long pane 3mm 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.

with Polycarbonate Glazing

with Polycarbonate Glazing (70902)

Polycarbonate is a virtually unbreakable material, better described as being a highly durable, 6mm thick twin-wall, opaque coloured plastic glaze rather than actual glass. This makes it the safest material where children and pets are concerned and the simplest type to install due to the large yet lighter panes. It also refracts the light very well.

Great Value for Money

Searched the internet for best buy and best quality, read reviews and decided on this greenhouse. Customer service is very good and delivery driver very helpful and rang before delivery. Quality of greenhouse is great, very sturdy with spacious headroom. Took ages to erect though. Majority of items were clearly labelled but not all, and some were hard to identify. The instructions are rubbish, put it together and took apart lots of times as put some parts on the wrong way round or missed out screws because diagrams/instructions weren't clear or non existent. Hooray for the internet, found a couple of websites that helped and youtube. Overall very happy with greenhouse and would recommend it.

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.
