Which glass do I need?

Horticultural Glass

This is standard greenhouse glass with 2' x 2' panes that overlap and join with S clips. This glass breaks into shards.

Toughend Glass

Recommended! Toughened Glass is much stronger than Horticultural glass and won't crack. If it does break it disintegrates into hundreds of small pieces.

Polycarbonate Glazing

Polycarbonate Glazing is ideal for family gardens where safety is the No 1 priority. It's virtually unbreakable and won't shatter.

Add a Base Plinth (Recommended):

Do I need a Base Plinth?

Frequently Asked Questions

  • What base would be best for my Greenhouse?

    For your greenhouse to thrive, it needs a solid foundation. Here are our top picks:

    Paving Slabs: A classic choice! They're easy to lay and provide excellent drainage.

    Concrete Base: Want something ultra-sturdy? A concrete base is your go-to option. It's long-lasting and provides a super-level surface.

    Decking: Yes, you can use decking! Just make sure it's robust and as flat as a pancake.

    Remember, a great base sets the stage for years of happy gardening. So take your time and get it right - your future plants will thank you!

    Now, this depends on what type you've chosen:

    • Ordered horticultural glass? It'll come neatly boxed up.
