To cover the metal frame of your polytunnel we supply hard wearing polythene polytunnel covers manufactured in the UK with the UK climate in mind. The polythene we stock is from a range of 'Visqueen' films that are manufactured using the latest technology, binding three separate layers of polyethylene together to produce an extremely strong and durable cover. We stock three different widths of polythene - 7.3 metres wide, 9.2m or 11.1m - in two different types - clear or opaque. The Clear Polythene uses the latest technology of UV stabilisers to ensure optimum light transmission of 91%. Whist the Opaque Polythene provides a uniform shading cover with a light transmission of 68%.
