KERTO-RIPA A RANGE OF WOODEN ELEMENTS Kerto-Ripa Open Light, strong, cost efficient and flexible, can be closed by wood panels or plasterboards for fire resistance or aesthetical issues, can easily be insulated with all kind of material either for acoustical or thermal performance. Holes and integrations can still be achieved on site if the slab is not completely finished and closed. Ideal for floors from 5 - 8m span or roofs from 10-15m either preferably for light and medium loads. Kerto-Q top panel Kerto-S ribs Kerto-Ripa Box Glued ribs with plates on top and bottom. Kerto-Ripa Box offers the most performing combination of stiffness, span, and small thickness. The Kerto plate underneath can bring up to 90 minutes fire resistance and visible look. Of course it can also be covered and insulation stays possible inside. Kerto-Ripa Box elements are often chosen for roof elements, but achieve also perfect results as a floor. Kerto-Q top panel Kerto-S ribs Kerto-Q bottom panel Kerto-Ripa Open Box Kerto-Ripa Open Box combines advantages of Kerto-Ripa Open and Box. This means gluing on both edges of ribs to reach a great rigidity, big spans and low height, still opened underneath to allow integrations. In Viikki (near Helsinki, Finland) 103 flats have been designed and erected, with those type of floor. Acoustical tests on site have emphasized the excellent behaviour of the complex reaching one of the highest European comfort standards. Kerto-Q top panel Kerto-S ribs Kerto-S flanges Kerto-Ripa Upside-Down Kerto-Ripa Upside-Down offers the same advantages than the Kerto-Ripa Open. The idea to put it upside-down allows fire resistance directly from the bottom Kerto-Q plate up to 90 minutes. Thus the Kerto can stay visible underneath and installation can be prefabricated or achieved on site. Either for floors or roofs, it can be closed with other standard panels. For residential uses we have tested compounds suitable with the highest acoustical requirements. Kerto-S ribs Kerto-Q bottom panel
