Nexus Foams were contacted to consult and manufacture a custom foam grade acoustic material, supplied as a 100mm cut-to-order SONEX profile. The application was a munitions testing facility for DSIR, and required a material which would stand up to the rigours of high noise levels.
The original material specification for melamine resin based foam posed issues; though the originally chosen material is both high performance, its costly, and brittle properties would have improved highly difficult to install and maintain. Nexus Foams consulted both the contractor and the architect on alternatives, which would capture the same acoustic performance, whilst addressing the durability concerns of the material itself. As a result, the specification was changed to a flexible and durable PU foam, cut to the SONEX profile.
