general properties and applications

There are a bewildering array of construction systems and techniques to consider when specifying your partitions, linings, ceiling and flooring.

For partitions, this is most apparent when the properties required of the finished wall call for more than one type of building board to be used in the construction. Bathrooms, for example, often require Moisture Resistance with Acoustic Insulation and Fire Protection. Other rooms will add Impact Resistance and flexibility in accepting wall mounted fittings to this. These criteria almost always demand compromise solutions involving specialist board selection and composite layers, often with costly and time consuming consequences. This in turn creates the potential for confusion, both at detailed drawing stage and on site. Additionally, multiple layering inevitably means thicker walls.

Fermacell offers a unique, single point solution to these problems, combining high levels of Fire Resistance, Acoustic Insulation and Impact Strength with exceptional weight hanging ability and Moisture Resistance.

From Commercial Projects through to self build DIY, Fermacell can reap rewards. Fermacell requires minimal additional work prior to painting and decorating. Wallpapers and tiles can be applied direct to the board, and plaster smooth finishes, which are ready to paint in about 45 minutes can be achieved by non-skilled trades using our FST (Fine Surface Treatment) system.

The end result is a finished partition that combines the properties associated with solid masonry with the flexibility of drywall, in a construction that is often thinner, quicker and cheaper to install than both. Using a multipurpose board that eliminates unnecessary wet trades makes practical, technical and commercial sense.

(1) Maximum stud centres = 50 x board thickness.
N.B. Where fixings are less than 500 mm apart, reduce the load per fixing by 50%. If a stud support separates the fixings, then use the full loadbearing strength shown above.

(2) Safety factor: 2 (Static load with relative humidity of up to 85%).

(3) Depth of cupboard or shelves: max. 350 mm.

(4) Standard toggle bolt with > 4 mm dia. screw.
(The toggle bolt manufacturer’s instruction should be followed.)
