{"product_id":"cumaru-prime-kd-glatt-terrassendiele-21x90mm-fixlangen","title":"Cumarú Prime KD smooth\n Terrace board 21 x 145mm fixed lengths","description":"Cumarú is one of the highest quality woods for patio flooring. This type of wood has a beautiful natural red\/brown tone. Cumarú also has a very high durability class, which makes this type of wood above average for outdoor use.\u003cbr\u003e \u003cbr\u003eThe natural area of ​​origin is northern South America. The durability according to DIN-EN 350-2 corresponds to class 1 and can be used without special protective measures for a long time without any restrictions. Cumarú has a density of 1,000 kg to 1,200 kg per cubic meter of wood at a wood moisture content of 12% to 15%, which means that an average standard plank with a cross-section of 21x145 mm has an average weight of around 3.3 kg \/ linear meter. The Brinell hardness is given as 45 to 58 N\/mm \u003csup\u003e2\u003c\/sup\u003e and is therefore significantly higher than that of the domestic white oak, for example.\u003cbr\u003e\u003cbr\u003e The term KD describes the drying method used to dry the wood from its fresh state to 16-18%. In this case, it is a technical drying process in a drying chamber under controlled conditions. (AD corresponds to air drying).\u003cbr\u003e \u003cbr\u003eCumarú has a relatively high swelling and shrinking behavior. The speed at which moisture is absorbed and released is, however, very low. The dimensional changes caused by swelling and shrinking must be taken into account when laying the decking. A gap of at least 4 mm must be maintained when laying the decking (with a wood moisture content of 16-18%).\u003cbr\u003e\u003cbr\u003e Carbide-tipped tools are required to work the wood. Due to the increased hardness of the wood, working is significantly more difficult. The wood must always be pre-drilled for the fastenings to prevent the fastening screws from turning off and also to avoid possible cracks in the wood.","brand":"Gunreben-Holz","offers":[{"title":"0.92","offer_id":45763090710681,"sku":"F01112001000-0.92","price":9.46,"currency_code":"EUR","in_stock":false},{"title":"1,53 m","offer_id":45763094970521,"sku":"F01112001000-1.53","price":14.61,"currency_code":"EUR","in_stock":false},{"title":"1.83","offer_id":45763090743449,"sku":"F01112001000-1.83","price":13.54,"currency_code":"EUR","in_stock":true},{"title":"2.13","offer_id":45763090776217,"sku":"F01112001000-2.13","price":20.34,"currency_code":"EUR","in_stock":false},{"title":"2.45m","offer_id":45763090808985,"sku":"F01112001000-2.45","price":23.4,"currency_code":"EUR","in_stock":false},{"title":"2.75m","offer_id":45763090841753,"sku":"F01112001000-2.75","price":26.26,"currency_code":"EUR","in_stock":false},{"title":"3.05m","offer_id":45763090874521,"sku":"F01112001000-3.05","price":29.13,"currency_code":"EUR","in_stock":false},{"title":"3.35","offer_id":45763090907289,"sku":"F01112001000-3.35","price":31.99,"currency_code":"EUR","in_stock":false},{"title":"3.66","offer_id":45763090940057,"sku":"F01112001000-3.66","price":34.95,"currency_code":"EUR","in_stock":false},{"title":"3,97 m","offer_id":45763090972825,"sku":"F01112001000-3.66","price":37.91,"currency_code":"EUR","in_stock":false},{"title":"4,27 m","offer_id":45763091071129,"sku":"F01112001000-3.66","price":40.78,"currency_code":"EUR","in_stock":false},{"title":"4,57 m","offer_id":45763091005593,"sku":"F01112001000-3.66","price":43.64,"currency_code":"EUR","in_stock":false},{"title":"4,88 m","offer_id":45763091038361,"sku":"F01112001000-3.66","price":46.6,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/2213\/0329\/files\/F01115101000-1.jpg?v=1738406403","url":"https:\/\/www.gunreben.de\/en\/products\/cumaru-prime-kd-glatt-terrassendiele-21x90mm-fixlangen","provider":"Gunreben","version":"1.0","type":"link"}
