Frequently Asked Questions

  • What are the different types of Polycarbonate Glazing?

    Clear Polycarbonate: This polycarbonate is completely clear like glass. It is very thin at 0.2mm, but extremely tough and shatterproof.

    Twin Wall Polycarbonate: This polycarbonate is virtually unbreakable and high impact resistant. They are slightly opaque, preventing strong sunlight exposure, yet offer 80% light transmission with high thermal insulation. The panels are 100% UV protected and will not discolour, fracture or shatter.

  • Is polycarbonate glazing strong enough?

    Yes it’s shatterproof and high impact resistant. However, as polycarbonate is very light, we do not recommend placing these greenhouses in exposed areas with high wind.

  • Does the greenhouse come with a floor?

    No, there is no floor or base. These greenhouses are ideally to be placed on a concrete, slab or decking base.

  • How do I secure the greenhouse to my foundation?

    We recommend securing the greenhouse to a hard, level surface (concrete, slabs, or decking) immediately after construction. This is essential for the stability and rigidity of your new greenhouse. You can use a screw and a washer through the compatible pre-drilled holes in the greenhouse frame into a raw plug in your concrete/slab surface.

  • Will you let me know when the delivery is?

    Yes, you will be notified by text where you can then pick which delivery day suits you. Easy!
