FAST Kerto-Ripa® combines the performances of Kerto LVL, the strongest and most advanced Engineered Wood Product, with a certified structural gluing technology, developed and implemented by Metsä Wood since the 90's. Kerto-Ripa wooden floor and roof elements are produced by off-site specialized companies all over Europe. Kerto-Ripa is an all-in-one high-performance prefab floor / roof element. With Kerto-Ripa spans of up to 24m, fire ratings up to 90 minutes and up to 75dB of airborne sound insulation are possible. Prefabrication means a quicker erection and a quicker return of capital. Actual projects have shown speeds up to 1000m2 per day using 2,4m x 16m Kerto-Ripa insulated and sealed box elements. Calculation and designing tools like Finnwood and Toolbox allow you to quickly design KertoRipa, fully compliant with EC5. LIGHT The lightness of Nordic premium spruce timber used to build Kerto-Ripa slabs allows architects, designers and engineers to imagine floors up to 15 meters, roofs up to 24 meters and to design elements 5 times lighter than standard concrete structures. The efficiency and optimized structures reduces the height of floors and roofs and offers savings in terms of foundations and lifting. As a result, adding storeys on existing buildings, long spans and cantilevers become possible. GREEN Metsä Wood is part of the 120.000 private forest owners cooperative called Metsäliitto. Sustainable development of our activities means that we carefully care of the 5 million hectares of forests that we manage, harvest, improve and use to process and bring the most advanced and ecological products to our customers in a very large range of applications. Naturally our mills are PEFC certified. Kerto-Ripa slabs help to design and build greener construction. KertoLVL production starts from Premium Nordic spruce logs which are conscientiously peeled, offering the best yield on raw material for a wood processed product. Moreover 1m3 of KertoLVL used in construction store sustainability 789Kg of CO2. Finally we have been implementing bioenergy towards our activities, geared towards industrial efficiency. Kerto-Ripa elements are an efficient and green application based on Kerto-LVL raw material that Metsä Wood supply to prefabricators. You can learn more on our sustainable activities here
