APPLICATION
The Ceiling Furring System is suitable for most internal dry lining applications. The system provides a high performance ceiling with sound insulation and fire protection that can be used for new ceiling structures or to upgrade existing ceilings. Ceiling height is variable to accommodate services, ducting etc. Our Metal Furring System is compatible with our Stud and Track Partitioning System and provides a flush finish for direct decoration or textured finish.
INSTALLATION
Perimeter Angle or Perimeter Channel is fixed to the walls around the edge of the room providing a location for the Ceiling Furring Channel. Primary Channel is suspended at a maximum of 1200mm centres using either one of the methods shown below:
A. RIGID ANGLE.
B. GALVANISED WIRE.
C. ADJUSTABLE ROD SETS.

Allowance must be made for the thickness and number of layers of plasterboard to be used. Fix the Furring Channels at right angles to the Primary Channel at 450mm or 600mm centres using Double Spring Clips.
Plasterboard is fixed using self tapping screws to the underside of the Ceiling Furring and Perimeter Angle/Channel.
When two layers of board are used, joints must be staggered.

FIRE TESTING
The Ceiling Furring System has been fire tested in accordance with BS 476: Part 23:1987 Section 5. The specimen tested was of overall nominal size 4000mm x 3000mm wide consisting of a steel framework comprising of Ceiling Furring Channels at nominal 450mm centres, which were fixed to Primary Channels with steel clips.
The Channels were suspended using Galvanised Angle at approximately 1200 centres. The underside of the Ceiling Furring Channels were lined with two layers of Diamond Plasterboard 12.5mm thick.
|
All joints were staggered with respect to those of the previous layer and the outermost joints were taped and sealed with joint filler to BS 6214.
The test was discontinued at 43 minutes giving protection of 40 minutes to the beams above. This therefore exceeds the 30 minutes fire test rating required in most applications.
Fire certificate is available upon request.
