NATURALSoundBlok – Reflective

Description

Gramm Barrier Systems NATURALSoundBlok® Reflective barrier range has a classic look most suited to rural environments. Gramm have spent a great deal of time developing our Timber Noise Barrier Range to provide high decibel reductions and 30 year maintenance free design life.

Unlike other systems, Gramm do NOT use a tongue and groove system, as timber naturally wants to expand and contract in the varying weather conditions which causes gaps to open along the joints allowing noise to pass through.

Gramm Barrier systems NATURALSoundBlok® Reflective timber noise barrier range uses a unique double acoustic board design on structural supports which allow the timber to move whilst maintaining an acoustic seal for the full life span.

Our range of timber barriers can be manufactured to suit the requirements of each individual site, ensuring the barrier system provides the highest level of sound reduction available.

Specification

Gramm Barrier systems NATURALSoundBlok® Reflective barrier are constructed off site under strict quality controls providing the highest level of construction which conforms to all the latest standards required for all sectors. Alternatively, our Timber Reflective range can be installed piece mill on site, to allow for varying ground conditions and obstacles.

NATURALSoundBlok® Reflective panels are constructed using incised, Tanalith E pressure treated timber which is sourced from an FSC approved supplier.

The panels consist of horizontal structural rails and structural gravel boards. The face side is then clad with vertical acoustic boards and cover boards and surmounted by a weathered calling. All elements are fixed using stainless steel annular ring shanked nails and fixings.
