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 Overlap Clips to worry about.
