“We have had a Keder polytunnel for about 10 years. Although we are in a very exposed position in Scotland, the polytunnel has withstood the violent storms and winds we get in this part of the world, without any damage. The “bubble wrap” covering is robust and provides insulation, again essential in this area. I would have no hesitation in recommending a Keder greenhouse, particularly if you are situated in an area with extreme weather.”
