Dear Business Partner
It is our top priority to serve you in the best possible way, despite the current turbulences with the Corona virus. I therefore want to give you an update on the status of the Sefar Group, which also includes Monosuisse.
• The Sefar Group complies to all the local regulations with respect to the containment of the Corona virus.
• We have taken additional internal precautions to assure the continuation of our production and the deliveries to you.
• All of our spinning and weaving plants worldwide are currently operating without limitations.
• There is a possibility of national restrictions in countries, where we operate our decentralized fabrication units. This may cause delays in fabricated items. For details, please contact your local Sefar subsidiary.
• Global limitations on freight capacity, in particular for air shipments, may also affect the delivery time.
Being a fully integrated supplier, Sefar controls and ensures the entire supply chain of our technical fabrics, from the yarn production at Monosuisse to the shipping of the fabrics or the finished articles. You are in good hands at Sefar.
Should your operation face any supply challenges where we might be able to help, please let us know. Your contact person is reachable at any time.
We will keep you updated on any changes affecting our delivery performance.
I wish you good health!
Sound absorption means the process of reducing sound energy, particularly (but not necessarily), by conversion to heat. ‘Absorbing’ is equivalent to ‘swallowing’ or ‘sucking in’. The term is used in a very similar way as is ‘sound dissipation’ and ‘sound attenuation’. The distinction given to dissipation is that the transformation of sound into other energy is understood, in particular heat; while in absorption other modes of the ‘disappearance’ of sound can be included (see sound absorption level). Sound damping, on the other hand, means any type of reduction in the sound intensity – which does not necessarily mean reducing the sound energy – for example by divergence, or by distributing the sound energy over a larger area. Two quantities, the absorption coefficient and the absorption level, are used for the quantitative determination of sound absorption.
For light ceilings, textile materials can be used which have a sound-absorbing surface. As a rule, this surface property is achieved by using a special woven structure or by perforation.
