The producer of technical textiles Low & Bonar Plc, London/UK, has signed a license agreement with the supplier of thermoplastic honeycomb technology EconCore N.V., Leuven/Belgium, for the use of their honeycomb technology.
Low & Bonar launched a new underlay flooring product at the Domotex trade show in Hanover/Germany, on January 10-13, 2020. The product, Colcore Sonic, uses EconCore’s continuous, high-volume production process for lightweight thermoplastic honeycomb sandwich panels. The underlay offers a unique combination of strength and acoustic performance.
The floor underlay product is deliverable on a roll, rather than as a rigid panel, making it very easy to handle, store and install. Colcore Sonic is lightweight and thin but with a high compression strength. It has very good soundproofing and levelling characteristics. It can be used with a range of hard flooring types such as vinyl click systems, flexible vinyl, laminate, hardwood and ceramic flooring.
Independent testing found that Colcore reduced impact sound by 20 dB and airborne sound transmission is 57 dB, both defined as the noise perceived in a room below. Radiated walking sound, defined as walking noise in the same room, registered at 56.4 Sone (a unit of loudness), considered to be a comfortable sound level, making the product suitable for flooring of both commercial and residential buildings.
