Key data We offer CLT rib panels made from Cross Laminated Timber (CLT) and glue-laminated timber (glulam) by Stora Enso. Enabling long span floor and roof structures, CLT rib panels provide more flexible and attractive layouts e.g. commercial office buildings, residential construction, schools, industrial buildings, long span roofs etc. CLT rib panels are made in a climate-controlled environment. They can be transported to the construction site just in time for assembly. You can install the CLT rib panels quickly, using regular tools and just a few carpenters. Stora Enso's CLT rib panels are...

Applications For spans longer than 6 metres, CLT rib panels provide an effective, economical solution. They have superior strength, stability and high loadbearing capacity, at a low weight and minimum material. This provides you new possibilities in design, as well as maximum structural performance using ~45% less material. The space between ribs can be used to route service lines or other installations. This can be ideal for public buildings that require good acoustic characteristics. Flexible, long span layouts for • Commercial office buildings • Residential buildings • Schools • Industrial...

Comparison to CLT At longer spans, CLT rib panels have a significant advantage in cost over other wooden floor types. By choosing a rib panel, a row of columns and beams can easily be omitted, increasing open plan space and making the layout more flexible.

The structural grid will impact the extent of open-plan lettable floor space and spans will typically fall into a range between 6 m and 12 m, with over 8m spans being very common in commercial office schemes.

Reduced number of elements means efficient construction programme Because CLT rib panels are prefabricated and lightweight, a quicker work flow is possible from delivery to assembly compared to other construction methods. No forming or curing time, no special equipment needed, reducing the noise and dust pollution normally associated with construction using non-renewable materials. It is important to maintain the speed of construction as the frame will be on a project’s critical path, so the allowance for sufficient craneage is paramount, coupled with the careful planning of deliveries and the...

Stora Enso’s Wood Products division provides versatile wood-based solutions for building and construction. The ribs are glued to the CLT panels using scientifically proven methods, that were established together with several research facilities across Europe. The pressure to the glue line will be applied by means of a screw glue application. While the screws will remain in the rib panels, they will not transfer any load in the regular service state. However they become essential for fire design. To ensure a proper quality in the structural glue line between rib and CLT, small samples are drawn...

BIM Toolbox To support building professionals, Stora Enso brings the building components to every architect and engineer's desktops. Stora Enso's product information is now available as BIM objects. Designers can find CLT and CLT rib elements as BIM objects (currently only for Revit), and many structural details in DWG and PDF format. The structure types and construction details are easy to find with a customised interface by clicking a specific part in the example building. ProdLib users need to download the product library first and after that the Stora Enso’s building components and systems...
