Gramm's ALUSoundBlok aluminium acoustic barriers consist of high-density mineral wool encased in aluminium panels, providing a lightweight and corrosion-resistant sound-absorbing barrier. They are perforated to protect and maintain the sound-absorptive capability of the fill material. Individual panels in the system can easily be removed and

GREENSoundBlok® is an innovative acoustic barrier based on an aluminium sectional frame for increased stability, with reinforced vertical bars for even higher noise barriers. It offers excellent sound-insulating and highly absorptive performance, classified in B3 and A3-4 on both sides. Tongue-and-groove interlock for easy stacking of multiple

The Hatko recycled rubber tyre noise barrier system has been specially designed to reduce noise generated by road, rail and industrial traffic. High-density Hatko panels focus on high performance and Net Zero and are exclusive to GRAMM as a UK partner. Being produced from recycled rubber derived from end-of-life tyres, Hatko is an extremely

WHIS®stone is a concrete noise defractor designed for quick and easy installation at roadsides. Sitting at the same height as the ground surface and taking up on 1m of road space, WHIS®stone will reduce traffic noise by 2.5dB, or up to 4dB when using a double row. The concrete elements are safe to drive over and have a drainage system installed

POLYSoundBlok® recycled PVC environmental noise barrier systems are manufactured entirely from high-strength reinforced PVC, negating the inherent issues that come from using timber. POLYSoundBlok is a highly durable rigid panel that will not warp or shrink, is rot-proof and resistant to aggresive environments and compounds such as salt spray and

Jakoustic® Absorptive acoustic fencing takes the proven Jakoustic® Reflective design but adds a Rockwool fibre absorptive layer on one side of the panel to keep noise within a contained space. Ideal for applications where a significant reduction in noise penetration is required, typically used to surround continuous power supply generators, waste

METASoundBlok® is a metal noise barrier system made from galvanised steel with sound-absorbing mineral wool, designed to reduce noise from road and rail traffic. Panels are lightweight, removable and fully CE compliant, with a perforated inner face for absorption and a plain outer face for reflection. Heights and lengths are customisable for

Aluminium Louvred Acoustic Barriers have been uniquely designed to provide high levels of sound reduction while allowing air to flow through. They can be installed in any location with either concrete-in or base-plated posts. Sound reductions of up to 30db are provided. Applications include: generator compounds; chiller compounds; data centres; air conditioning

TILESoundBlok® noise barrier tiles are manufactured from carefully selected specialist aggregates with angular face which are bonded together using the company's patented method. This allows the system to use a low amount of binder while still retaining a strong bond, resulting in a robust material ideal for sound absorption in a variety of

Greenscreen is an environmentally-acceptable flexible and natural noise barrier and, using technology developed in the professional growing industry, it is designed to support climbing plants. Over time the screens become completely clothed in foliage, creating a natural 'greenscreen' barrier. The barrier's pleasant aesthetic blends in with any
