Customisation > Glazing
Glass diagram images below are for demonstration of the glazing styles and may differ depending on your chosen greenhouse model.
with Long Pane Toughened Glazing (70945)
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.
- 6% Off
- Save £99.01
with Polycarbonate Glazing (70904)
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.

Assembly of Magnum Greenhouse
The Product is perfect, but the Instruction manual leaves a lot to be desired, since it is not an instruction manual. It is a list of drawings with Part numbers. It does not make clear when and where to install the captive nuts, and so often parts had to be undone again to slid in further nuts. The Cast Aluminium corners are difficult to fit and require a lot of levering to get the nuts in. This needs a step by step guide. Very satisfying to have completed it. Is a great product

It's looking good already
I'm still in the process of building this greenhouse, in fact I've only just started but the good news is that it's looking great already. I suppose I'm lucky having a decent patch of ground for a bigger than normal greenhouse but I've recently got into growing chillies and want to start a bit of a business. We'll see how it goes but so far so good. Initially I was attracted by the good ventilation and wide sliding doors, but the rest of the greenhouse seems up to expectations as was GardenSite's service and delivery.
