I had trouble finding the shiplap in local stores for my project but at the end I found RUBI. The website is amazing, you can search easily and you have all the information, details you need. They know their products, they know what they sell. I mean you can see the professionalism here. Customer support is very friendly and helpful. The wood itself looks good, straight and smooth. The only thing I could mention, some of the boards are a bit shorter, like 1cm or so, but honestly you can expect that. I will definitely l buy again for my next shed or similar project. I can only recommend RUBI uk!
