At nortenergy, we’re very proud of our polycrub. It’s a tremendously strong structure, and is built with a solid green ethos. The frame is made from recycled salmon pipe, which gives this material another new, long, useful purpose. During the last few years, several kilometres of waste salmon pipe have been diverted from landfill in Shetland.
The polycrub is covered using twin-wall polycarbonate. This is not the cheapest form of cover for a polytunnel/greenhouse structure, but we use it because we are confident that it has the longest lifespan of anything available.
Twin-wall polycarbonate is also certainly the most durable. Shetland has a well-merited reputation for wind, and we think the polycrub can withstand quite a bit of it! If the polycrub can stand up to our winter gales here in Shetland, it can survive anywhere.
The polycrub is a much more permanent structure than many of the kit-form polytunnels. For this reason we advise customers to check with the Local Planning Authority whether a chosen site will require planning permission or Agricultural Prior Notification.
Like anything around the home and garden, we recommend that polycrubs given an annual maintenance check.
