Toughened Safety Glass

Toughened Safety Glass

Toughened Glass is much stronger than Horticultural glass and won't crack. If it does break it disintegrates into hundreds of small pieces that are unlikely to cause injury, unlike Horticultural Glass which breaks into shards. It's heavy weight also means it's the best glazing option for windy spots and the UK in general!

Full Length Glass (Long Pane)

Toughened Glass is long pane, meaning each panel in your greenhouse is one piece of glass. No unsightly overlaps where dirt and grime can collect and no clips to worry about.

  • Green Aluminium Frame.
  • Box Section Ridge Bar.

  • 4x Opening Roof Vents.
  • 10 Year Warranty (Frame and Base).
  • HALLS ACCESSORIES - ADD BELOW.

The 8ft 5" wide Halls Magnum 8x12 with double doors is a great greenhouse for the keen gardener or allotment keeper with room for a larger greenhouse.

The Halls Magnum 8ft x 12ft Greenhouse will give you more than enough growing space to bring on seedlings as well as grow salad, herbs and vegetables all year round. The great thing about an 8ft wide greenhouse is the working space inside that means a couple of you can be toiling away potting up or plants without bumping into each other. The extra width also gives you more planting options such as using large raised beds or tubs for vine plants.

The Magnum is strengthened at the eaves and ridge by using cast iron joints as well as the actual ridge bar itself being constructed from thick box section. These strengthening features will keep the greenhouse rigid and square in strong winds.

Halls toughened safety glass is a long single sheet that goes from base to eaves and a long single pane for each roof section. Toughened glass is recommended for gardens where children or pets are around as it won’t break into dangerous shards like standard greenhouse glass but into small pebbles like a car windscreen. Toughened safety glass is also far better if you live in a windy spot as it’s heavy meaning it won’t blow out in high winds and makes your greenhouse generally more stable as a result.
