A COMMITMENT TO THE ENVIRONMENT The environmental credentials of Metsa Woods Finnfiame System are without parallel. Finnfiame satisfies the most stringent requirements for sustainability. Our commitment to renewable resources begins with the 116,000 private Finnish forest owners from whom we procure most of our timber At every stage thereafter we control distribution, manufacture and sales of our products. That unbroken chain from sapling to selling gives us an unrivalled ability to trace the source of timber products. We take our environmental responsibilities as seriously as you do. We...

The Finnframe Floor System does the job of specifying for you. It converts your own floor plans into a 3-D image of the supporting structure together with a complete bill of materials and detailed plans for construction. Those plans go with our Finnjoists and other engineered wood products to provide a comprehensive drawing-board to building-site flooring system. The Finnframe Floor System is an inspired mix of quality, technology and service - a total flooring system devised specifically for the UK construction industry. It was the first flooring system to comply with Eurocode 5. FULLY...

The Finnframe App was developed to eliminate errors in the installation process of the Finnframe Floor System to help get the job done right first time, every time. It provides static drawings of design details and animated sequences demonstrating the correct installation procedure to ensure the build process is more efficient and helps both the contractor and client. This information is currently provided in the form of technical drawings on the reverse of detailed site plans. This guidance may not be readily to hand for all contractors, so the app provides immediate on-the-spot...

FINNJOIST (Ell) Finnjoist (FJI), forms the heart of our floor system. Manufactured in the UK at our purpose-built factory in King s Lynn to exacting tolerances, the Finnjoist (FJI) with its Kerto* flange and high quality OSB web has a high strength to weight ratio and therefore produces lighter, longer spans of up to 14 metres, combined with quick and easy installation so reducing your build time and increasing efficiency. Finnjoists have full 3rd party accreditation through the BM Trada Q-Mark and are the first product on the market to gain the European Technical Approval (ETA) and the CE...

Manufactured by Metsa Wood since 1975, our Kerto* is a unique product which not only serves as the flange material for our (FJI) I-Joists but is the perfect choice for long spans, rimbeams, lintels and high-load structural applicadons. Kerto* is CE marked, carries BBA certification and PEFC environmental accreditation. Kerto is produced from rotary-peeled 3 mm graded softwood veneers, which are then gjuedtogetherto forma continuous 1.8 or 2.5 metre wide product. The 21mm to 90mm thick sheets are then further machined to the finished dimensions. The result is an engineered wood product that...

TECHNICALLY ADVANCED Simple to use, giving you the advantage A programme of continuous development and advancement has given us the Finnframe software package, allowing you to view designs in 3D as well as plan view. Finnframe will deliver clear and concise material listings, structural and assembly drawings, and is designed to calculate to BS EN 1995-1-1. Finnframe is also able to link with other software programs including drafting, stock control and CNC cutting programs, a feature unique to Finnframe. Finnframe can import or export IFC models for full BIM compatibility and is also able...

GENERAL FLOOR PERFORMANCE The performance of a floor is a subjective matter, expectations differ significantly between individuals. The main performance criteria being quietness and amount of deflection. Minimum standards are governed by current legislation but may not give the personal expected performance. The most important factor influencing floor performance is stiffness. Improving stiffness decreases deflection, bounce and vibration. FLOOR STIFFNESS CAN BE IMPROVED BY: Stiffness The ability of a material to resist deflection under load. Vibration Resonance of material. In floors...

In any floor design the weights of the applied loads must be calculated. The permanent loads or dead loads are those that form the structure and finishes. The imposed or live loads are those considered appropriate for the use of the floor such as furniture or human foot traffic. Live load information can be obtained from BSEN1991-1-1 Chipboard refers to moisture resistant chipboard P4 and P5 to BS EN 312. OSB 3 to EN 300. Plywood to be to the requirements of EN 13986. 12.5mm Fire Check Board 0.12 12.5mm Plasterboard on both sides of the timber 0.29 Glass Wool Slab per 25mm depth 0.01 Glass...

Standard domestic floor condition with allowance for non-load bearing partitions up to 0.66kN/m. Maximum clear span (L) for single span conditions. Performance classes as defined on page 10. GENERAL NOTES: a. Metsa Wood recommend that the decking is glued and fixed in accordance with British Standards. This can significantly improve the floor performance, b, Deeper I-Joists will perform better than shallower I-Joists due to better deflection performance, c. The depth of the floor decking influences performance with deeper floor decking improving stiffness, d. Appropriate strutting of the...
