Furring


Designpanel 900/1200



BD-30 (EI30) construction
The steam blocking is placed over the furring. If the steam blocking is placed immediately over the perforations, but under the furring, the ability to absorb the sound is severely reduced. The present absorption data depends on a 150 my (µ) plastic foil. A foil with any other thickness will affect the acoustic capacities. In order to achieve a BD-30 construction, 250 mm stone wool must be a part of the construction.

Furring, wood
The ceiling is fitted to a plane wooden furring 25 x 100 mm. The furring is fitted to the rafter or beam with a maximum central distance of 1000 mm. The furring is fitted perpendicular lengthwise to the ceiling panel. The maximum c/c distance of the furring is 300 mm. The short edge joints must be supported.

Furring, steel
The ceiling is fitted to a plane steel furring of the CD-type.
The system consists of primary framework at a maximum distance of 1000 mm and secondary framework at a maximum distance of 300 mm. Along all walls and columns wall profiles UD 28 x 27 are fitted, which are screwed onto the furring at a maximum distance of 400 mm.


The brockets are fitted at a maximum distance of 900 mm to the adjacent construction and connected with the anchored beam to the primary CD-60 supporting framework. The cross fitting is placed onto the supporting framework at every 300 mm to which the adjacent framework is attached. It is necessary to have furring underneath the short edge joints.
