* Qbiss One elements are differentiated based on type of mineral wool being used, depending on thermal insulation requirements and structural spanning needs. 

For most used element types (1,2,3,4), the minimum length of the element is 500mm. Qbiss One with all other element types (5,6,7,8,9,10,11 and 12) spans from 550mm to 6475mm.

Calculated according to EN 14509 standard without consideration of longitudinal joint losses.
