| Description of the area of application: | LIGNO® Rippe is a configurable cross-laminated timber ribbed element designed for load-bearing floor slabs with high sound and fire protection performance. It is suitable for single-family homes as well as multi-storey buildings, schools, or office spaces. Integrated longitudinal and transverse channels allow for flexible installation routing. Usually, the elements are supplied with visible surfaces—such as knot-free white fir—and feature a slatted underside with acoustic absorbers to meet high architectural design standards. Large spans can also be achieved. | ||
| Product description of manufacturer: | LIGNO® Rippe-x is a material-efficient cross-laminated timber ribbed element designed for use as a sound-insulating and structurally robust floor slab component. It features three load-bearing ribs, with the lower closure of the cross-section formed by a CLT-layer. The element height is adapted to meet structural requirements and can be configured with additional layers for fire resistance of up to 90 minutes. High-quality genuine wood surfaces are available on the visible side—optionally with integrated acoustic profiling. The crosswise lamination ensures excellent dimensional stability. | ||

| natureplus product test: |
The natureplus product test is considered the most comprehensive sustainability test for building materials in Europe:
✓ Verification of all information at the manufacturing plant
✓ Laboratory analysis and expert reports by accredited partners ✓ Regular repeat tests | ||
| healthy living: |
Building products with the natureplus label do not harm the environment or human health with pollutants and, in particular, ensure healthy indoor living spaces.
✓ AgBB scheme Germany (laboratory analysis of emissions according to EN 16516)
✓ EU taxonomy ✓ QNG-compliant * *Exception: cellulose products containing boron do not currently comply with QNG. | ||
| climate protection: |
The manufacture of building products is environmentally friendly and energy efficient, thus contributing to climate protection and CO2 avoidance, and fulfilling social responsibility. The products must be fit for use and recyclable.
✓ CO2 footprint (CFP according to EN 14067) is below the average for comparable products.
✓ Primary energy requirement is below average for comparable products. ✓ Above-average use of renewable energies in production. | ||
| ressource conservation: |
Only construction products made from at least 85% renewable or abundant mineral raw materials or secondary raw materials are eligible. The raw materials must come from sustainable sources.
✓ Social requirements are checked at the production sites.
✓ Investigation of upstream suppliers in the supply chain. ✓ Reuse and recycling through material quality and dismantling instructions. | ||
