8ft Wide Polytunnels

If you’ve chosen an 8ft wide domestic polytunnel, it’s important that you get the construction of it right. First Tunnels have compiled two PDF construction guides for both Base Rail and Trenching versions of the 8ft wide polytunnel. They contain instructions, details on tools needed, and much more to ensure your 8ft polytunnel build goes smoothly. Download the guides today or get in touch with our construction team for further assistance here.

They're called QR codes, and we're using them to give you easy access to our construction videos...

No typing, no searching for the right video, just a simple scan (1) of the code with your smart phone and you’ll be instantly connected to that construction video (2). Perfect for when you’re outdoors and could do with the reassurance of seeing what you’ve got to do next.
