1)
The stated heights apply to constructions with a profile spacing of 600 mm. When a structure with profiles spaced every 300 or 400 mm is used, the permissible wall height increases. Contact system provider representatives for details. The stated heights apply to rooms where only a few persons are present simultaneously (e.g. rooms in flats, hotels, hospitals). In rooms where a large number of persons are present simultaneously (e.g. conference rooms, classrooms, lecture halls), the permissible height is 3.7 m.
2)

Based on classification no. LBO-127-KZ/24 for 50 mm rock wool

3)
The weight specified does not include the insulation material weight.
4)

Based on report no. A 211002 for 2x50 mm glass wool

Q1 - Double filling of plasterboard joints and connections with a structural joint filler (Norgips Start & Finish or Norgips Star), sealing a reinforcing tape, covering visible fasteners with a joint filler

Q2 - Includes the Q1 scope plus filling plasterboard joints with a finish joint filler (Norgips Extra Finish, Norgips Start & Finish or Norgips Finish) until a smooth transition of a joint into a plasterboard surface is achieved

Q3 - Includes the Q2 scope plus filling the entire partition element (joints and cardboard) with an approx. 1 mm thick layer of finish joint filler (Norgips Extra Finish, Norgips Start & Finish or Norgips Finish) to level the surface, close all pores and consolidate absorptivity of filled surfaces
