KVH

    Surpassing the standards 

    KVH® by Stora Enso surpasses state-of-the-art. With its precisely specified dimensions and high quality control, it satisfies the demanding requirements of house owners, designers and craftsmen alike. And with its attractive planed surfaces and speedy delivery right to your site, you can count on KVH time after time. 

    KVH (Konstruktionsvollholz) is solid structural timber typically made from spruce softwood and used in modern timber construction. Other softwood types, like pine, are available on request for special uses like wooden thresholds or outdoor areas not directly exposed to the weather. 

    We produce KVH in standard cross-sections to cover all the structural and visual requirements of modern timber frame construction. 

    Structural timber with quality a cut above the rest 

    KVH structural timber is sorted, calibrated and has precisely defined dimensions and load-bearing capacities for both visible and non-visible areas. Compared with conventional sawn wood, KVH must conform to much stricter requirements. The timber is graded in accordance with EN 14081 and German standard DIN 4074-01. Compliance is monitored by third-party quality inspection institutes. 

    Kiln dried and cut for dimensional stability 

    To ensure a lower moisture content, we kiln dry KVH structural timber using an automated process to a maximum residual moisture content of 15% ±3%. This gives you maximum dimensional stability. KVH is cut split-heart or free-of-heart to help minimise cracking and twisting. 

    With KVH, you won’t need to worry about twisting, warping, discolouration or damage from insects. 

    Different surface qualities for exposed or non-exposed applications 

    We offer KVH in 2 surface qualities: KVH-Si for visible structures and KVH-NSi for non-visible structures, and in lengths up to 16 metres. Both types come finger jointed, and the joints are barely visible as to preserve the natural look of the surface. 

    Duo/Trio beams 

    Duobalken® and Triobalken® laminated beams are larger cross-sections (two and three face-bonded planks, respectively) that offer the same outstanding dimensional stability, low moisture content and minimal splitting as KVH. They feature fewer glued joints than regular glue-laminated timber, and greater rigidity than solid timber of the same strength class. Ideal for exposed applications that have high aesthetic requirements without the use of chemical wood preservatives. 

    Safe, strong and sustainably produced

    KVH and Duo/Trio products are bonded using formaldehyde-free adhesives. This makes them highly sustainable, safe products. 

    Like all of Stora Enso’s wood products, wood supply chains are covered by third party verified traceability systems according to PEFCTM and/or FSC®. And, all of our wood manufacturing units have a good coverage of third-party certified management systems for quality (ISO 9001), environment (ISO 14001), and occupational health and safety (OHSAS 18001). These certifications guarantee that KVH, Duobalken and Triobalken are produced according to the highest environmental and ethical standards. 

    Custom orders – hassle-free

    Standardization brings obvious advantages to trade and the processing industry: made to stock, high availability, short delivery times, and cost-effective planning and construction. Avoid order picking or repackaging – ask us to customise our standard lengths. Stora Enso can produce structural beams and timber for your specific needs, flexibly and fast.
