Kerto-ripa Long-span Engineered Timber Solutions Tm




TM Kerto-Ripa LONG-SPAN ENGINEERED TIMBER SOLUTIONS 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.

FLAT OR LOW PITCH ROOFS Roof covering to design specification Its rapid installation (up to 1000m2 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 Thermal insulation to required depth Kerto-Q panel Main frame Ma x 18 m Main frame ROOF PANEL DIMENSIONS MAX SPAN L (mm) MAX SNOW LOAD (kN/m2) 0.6 1 8000 230 230 9000 275 275 10000 310 310 12000 350 410 13000 410 450 14000 450 500 16000 550 550 18000 650 650 NOTES: EXAMPLE DEPTHS; OTHER DEPTHS POSSIBLE ON REQUEST.

KERTO-RIPA TM – LONG-SPAN ENGINEERED TIMBER SOLUTIONS 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.

The 21mm to 90mm thick billets are then further machined to the finished dimensions. 1 Sawing 5 Gluing 9 Rip-sawing 2 Rotary Peeling 6 Layup 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 7 Hot Press 4 Drying 8 Cross-cutting There are two key types of Kerto: KERTO-S KERTO-Q WITH LONGITUDINALLY LAID VENEERS WITH CROSS 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. Produced in a similar way to Kerto-S but with approximately 20% 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 For more information visit or call our technical team on 01205 883 835.
