*Dropdown Boxes Information*

The Halls 8x12 Magnum greenhouse offers a large growing area with a very sturdy frame, plenty of room inside for the tallest of gardeners due to an increased eave and ridge height. The Magnum has braces on each eave and across each roof apex, also strong cast joints at the corners and ridge ends along with the box section ridge make this a very strong greenhouse for the UK weather conditions.
Comes as standard with 4 roof windows, together with large double sliding lockable doors on the 8ft5" width.

Our View
The Magnum is our top selling range of 8ft wide greenhouses. Big and spacious with lots of bracing for strength this is a perfect greenhouse for the keen gardener. One big plus we have found when installing is that because of the diagonal braces found on each of the 4 sides combined with diagonal braces from each corner of the roof that they pull the greenhouse nice and square, this makes glazing and fitting doors and windows much easier!

Glazing

Horticultural Glass

Standard greenhouse glass supplied in 3mm thick overlapping sheets.

Toughened Glass

Halls only use toughened glass to British standard, this is long pane sheets for a neater finish and eliminates any overlapping which can have an algae and moss build up. Much stronger than horticultural glass these panes will granulate if broken removing the danger of serious injury.

Halls Base

The Halls base is a must for most people, this handy accessory replaces the need to build a brick surround or similar.All greenhouses need to be well supported and this has been manufactured for this exact greenhouse and makes a strong footing that will last as long as your greenhouse.
This enables the greenhouse to be sited on nearly any firm surface and is suitable for soil, grass, concrete, slabs, decking etc.
Supplied with ground anchors and all necessary brackets to attach to your greenhouse, this also has the added benefit of adding 128mm to your greenhouse height.
Supplied in a galvanized steel finish to suit the silver aluminium greenhouse frame.

Without the base you will need to build a raised plinth to the exact measurements of your greenhouse.

Installation

Halls UK Installation

Have your greenhouse installed by Halls, this service is available to the whole of mainland UK.
Installation must be on to a prepared hard standing such as concrete or slabs, and the Halls base purchased.

Louvre

Louvres provide low level ventilation and are an excellent accessory.
