Black wool serge has been used in the theatre and events industries for years, as it has properties which are great at reducing unwanted sounds and echoes, and it is also useful for keeping out or keeping down light.
Black wool serge curtains are made from sheep’s wool which is woven to produce a fabric which is thick and rich, and is also very durable, which is ideal for controlling acoustics. In addition, the fabric is inherently flame retardant and conforms to BS 5867 Part 2B. However, if you are going to use wool serge for upholstery it will need to be back-coated so that it conforms to BS 5852.
When used to control acoustics, black wool serge drapes can be used around the stage in order to dampen sound travelling and reverberation of sound which can spoil a performance. The thicker the fabric and the more pleats there are, the better it will prevent the sound waves from travelling.
The fabric will also produce a very effective dim-out, although not complete blackout. If you want to completely block any light the curtains would need to be lined.
Wool serge is available in various widths, from 120 cm to 180 cm, and it can vary in weight. The grams per square metre run from 330 gsm up to as much as 1 kilogram, although the average in the industry is 500 gsm. Wool serge is a budget product and therefore ideal for use within the theatre business.
