The term ‘soundproof’ is often used to describe acoustic treatments and is very misleading. It is not physically possible to provide a ‘soundproof’ curtain. The reduction of sound is controlled by the density of the barrier placed between the sound source and the receiver. Our curtains are, however, very effective at reducing sound from speech frequencies up to higher pitched sounds.
The first step is to determine whether you need a sound absorptive curtain to control reverberation, or one that will also reduce the transmission of sound. All of our single layer fabrics provide good absorption, but double or triple layer constructions, using heavy fabrics, are usually necessary where sound reduction is required.
Sound absorptive products, such as curtains or wall/ceiling absorbers will not reduce any direct sound between the source and receiver, they will only help to reduce the effects of reflections that would otherwise cause a muddled build up of sound within the space. Sound reduction is exactly that, although even the heaviest curtains, are restricted in this respect.
All of our fabrics offer good sound absorption, choice is therefore usually based on budget considerations and/or aesthetic appearance. Black wool serge is generally the least expensive. If velvet is being considered, then lining may be necessary if used over glazing, as this fabric is only faced on one side.
This will depend on whether you are dividing a space or want to reduce sound transmission through windows. For the former we recommend either a double or triple layer construction using coloured wool serge or velvet velour facing fabric to each side, with the triple layer also using an inter-lining. For windows we recommend the use of either coloured wool serge or heavy velvet velour, lined with black wool serge.
This is expressed as a percentage ie. If we manufacture to 50% fullness, then the width of fabric used to make the curtain is 1.5 x the headed width or track length. 70% corresponds to x 1.7 x and 100% to x 2.
For most applications this is pretty straightforward, we just need to know the width of the curtain, which will be nominally the same as the track length and the height (or drop). For sound absorptive curtains this will usually be dictated by the wall area to be covered. With curtains that are dividing a space or covering a structural opening, this will again be just a straightforward width x height. Windows are a little different, as curtain size will depend on factors such as how much overlap you require to either side, the top and the bottom. The drawing below should help you provide us with the correct measurements.
This will depend on how the curtains are being hung and what type of track is to be used. Examples of the various headings offered can be found here. It should, however, be noted that we cannot provide domestic style pleating due to the heavier nature of the fabrics used. Our domestic curtains are provided with a Rufflette tape heading as per standard domestic curtains.
For most domestic applications the Silent Gliss 1280 track is the neatest and most economical solution. With particularly large or heavy curtains it is best to call us for advice.
We can supply both of the above but care needs to be taken to ensure that the correct track is selected for the curtain weight. Please call for advice.
We can arrange installation through our own sub-contractors or through partner companies, although for most domestic jobs we suggest that self installation is both easy and economic, as we provide full details and guide you through the process.
We do not supply curtains from stock. All of our curtains are tailor made to meet your specific requirements, with despatch usually around three weeks after receipt of order.
