Ludvig Svensson curtain, acoustic and upholstery fabric, woven in Sweden
Hume Internationale has been Ludvig Svensson's exclusive distributor in Australia and New Zealand since 2020. Ludvig Svensson was founded in Sweden in 1887 and makes hanging and upholstery fabric for public spaces. Svensson weave all of their interior textiles at Kinna, Sweden, and own the whole process, from the design and the choice of yarn to the finished cloth. The same company makes climate screens for commercial greenhouses, which manage light and heat over a crop.
Sound absorption, measured and classed
Svensson classify their acoustic textiles by measured performance. Absorption is measured in a reverberation room to ISO 354, and the result is a coefficient between 0, where all sound is reflected, and 1, where all of it is absorbed. The coefficient places the cloth in a class from A to E, with A the highest. Svensson's curtains are tested by an independent laboratory, hung at 10 and 15 centimetres from the wall. On Svensson's figures an ordinary curtain absorbs 0.10 to 0.15 and an acoustic curtain 0.35 to 0.70. Two installation details change the result. Svensson give 10 centimetres from the wall or glass as the minimum, and the more folds a curtain carries, the more sound it absorbs.
Trevira CS
Svensson weave in Trevira CS, a polyester that is flame retardant in the fibre rather than through a finish. Nothing sits on the surface to wear off and nothing needs reapplying over the life of a fitout, which matters on a curtain that is drawn and cleaned often. How the certification travels with the cloth is set out on the Trevira CS page.
