Sylva™ CLT or LVL Rib Floors and Roofs

  • GWP Total: 32.42 kg CO₂e/m²
  • GWP A1-A3: -101.55 kg CO₂e/m²
  • Prefabricated and lightweight panels allow for rapid workflow from delivery to assembly
  • Yield more square footage with less raw material
  • Enable flexible floor plans that can be easily repurposed for changing needs
  • Less need for beams and load-bearing walls gives more architectural freedom
  • Space between the ribs can be used to route services or other installations

Rib Panels are mass timber products that can be used for long-span floors and roofs where high load-bearing capacity and low self-weight are required.

Stora Enso offers two types of Rib Panels: made from CLT combined with GLT (glulam) or from LVL. All of the Rib Panels can be installed quickly and easily on-site and are CE-marked.

 

Applications

For spans longer than six meters, Rib Panels provide an effective, economical solution. They have superior strength, stability, and high load-bearing capacity, at a low weight. This provides builders and designers with new possibilities in design, as well as maximum structural performance using 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. Because rib panels are prefabricated and lightweight, builders can get a faster workflow from delivery to assembly compared with other construction methods. There is no forming or curing time and no special equipment is needed.
