best wood CLT BOX - ROOF open box element for passive house construction

best wood CLT BOX - ROOF consists of best wood CLT with two glued-on glulam ribs.
The combination of CLT and ribbed wood results in a high static load-bearing capacity with comparatively low weight. The crosswise construction of high-quality raw material in combination with high-quality flank and surface bonding ensures a high degree of dimensional stability.

Advantages

  • high static load-bearing capacity with comparatively low weight
  • large spans and therefore prop-free rooms possible
  • high degree of prefabrication and simple joining of the roof elements for swift and cheap installation
  • utilises advantages of solid timber and wood frame construction
  • high resistance to fire
  • outstanding insulation characteristics due to insulation of spaces for passive house construction
