2 KERTO-RIPA The Kerto-ripa panel is a structural engineered timber building element made from glued Kerto members. It is used to create the ground, intermediate floors and roofs of residential, commercial and public buildings. Kerto-Ripa can be used in both thermoinsulated structures and non-insulated structures.

3 BENEFITS FOR THE CONTRACTOR Fast installation up to 1000m of weather protection in one day Reduces the need for protective covering during construction at the building site Pre-fabrication ensures even quality Reduces turnaround time for construction projects Carefully-timed delivery for the building phase Clear, long spans Environmentally sound TYPES OF PANEL OPEN PANEL htot Kerto-S rib 1800mm or 400mm or 500mm CLOSED PANEL Kerto-S rib htot 1800mm or 400mm or 500mm Ceiling finish to required spec CLOSED PANEL INSULATED Can be designed to meet client requirements htot Insulation Kerto-S rib 1800mm or 400mm or 500mm Ceiling finish to required spec 07/ CPD-0577 LONG-SPAN ENGINEERED TIMBER SOLUTIONS KERTO-RIPA TM

4 ROOFING SOLUTIONS Kerto-ripa panels are an ideal solution for flat or low pitch roofs, and can be designed to the client's thermal requirements. Its rapid installation (up to 1000m a day) provides a weatherproof seal for the building, reducing the need for a protective covering during construction. Long clear spans (up to 18m*) are available allowing buildings to be constructed with fewer columns and beams creating greater design flexibility. *Transportation costs to be considered for spans over 13.5m FLAT OR LOW PITCH ROOFS Roof covering to design specification Thermal insulation to required depth Main frame Max 18m Main frame ROOF PANEL DIMENSIONS MAX SPAN L (mm) MAX SNOW LOAD (kn/m ) NOTES: EXAMPLE DEPTHS; OTHER DEPTHS POSSIBLE ON REQUEST. FLAT ROOF WIND CONDITIONS APPLIED. FOR OTHER CONDITIONS PLEASE CONTACT OUR TECHNICAL TEAM ON KERTO-RIPA TM LONG-SPAN ENGINEERED TIMBER SOLUTIONS

5 FLOORING SOLUTIONS Kerto-ripa panels are also suitable for both ground and intermediate floors delivering clear spans of up to 9m. The panel is pre-fabricated to allow quick and simple installation, easily accommodating coordinated services within the floor zone. For cases where increased acoustic performance is required, The SoundBar System can be added to exceed building regulations. GROUND & INTERMEDIATE FLOORS Optional Metsä Wood SoundBar acoustic deck shown.

7 KERTO Manufactured by Metsä 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 applications. Kerto has BBA certification and PEFC environmental accreditation. KErTo CErT: No 00/3717 PEFC/ Promoting sustainable forest management for more info: Kerto is produced from rotary-peeled 3mm graded softwood veneers, which are then glued together to form a continuous 1.8 or.5 metre wide product. The 1mm to 90mm thick billets are then further machined to the finished dimensions. 1 Sawing Rotary Peeling 5 Gluing 6 Layup 9 Rip-sawing 10 Despatching The result is an engineered wood product that maintains the natural beauty of wood whilst being strong enough for most types of construction applications. 3 Clipping 4 Drying 7 Hot Press 8 Cross-cutting There are two key types of Kerto: KERTO-S WITH LONGITUDINALLY LAID VENEERS Produced so that all its veneers are laid in the same direction, Kerto-S delivers a product perfect for beams whatever the specification and for achieving long spans with minimal deflection. KERTO-Q WITH CROSS LAID VENEERS Produced in a similar way to Kerto-S but with approximately 0% of its veneers laid crossways, Kerto-Q delivers exceptional dimensional stability and performs well where high compression strength is required. Kerto-Q is ideal as a rimboard in timber frame construction. LONG-SPAN ENGINEERED TIMBER SOLUTIONS KERTO-RIPA TM
