Industry leading acoustic performance

At Optima, we have an unrelenting desire for excellence through innovation. As one of our core values, innovation plays a vital role in everything we do and this has led to the delivery of industry-leading acoustic performance. We shaped the industry by introducing frameless glass partitioning to the UK market over 30 years ago, dramatically transforming office environments and opening up exciting new design possibilities.

As design trends and client requirements have evolved over the years, so too have our award-winning products. Our technical expertise, our investment in product development, and our passion for excellence, have enabled us to create exceptional glass partitioning systems that offer market-leading acoustic performance.

Through innovation and a commitment to driving acoustic standards forward, we are leading the glass partition Acoustic Revolution.

Rigorous Acoustic Testing

Sound reduction performance, in essence, is the ability of a partition to reduce the amount of noise that passes through it. As leaders of the glass partition Acoustic Revolution, we know how important it is to give our clients accurate and verified acoustic test data. 

The Sound Reduction Index, or SRI, is measured by testing a partition sample in an acoustic laboratory in accordance with EN ISO 10140-1 and 2. The results are then weighted as a single number value in accordance with EN ISO 717-1 and expressed in dB (Rw). This method of measurement, under controlled laboratory conditions, allows evaluators to make precise comparisons between similar products.

For an informed and accurate comparison of the acoustic performance of similar glass partition systems, it is vital that the laboratory-tested Rw(dB) value of each system is analysed. This will provide a fair contrast when reviewing or specifying apparently comparable systems. In addition, it provides peace of mind that the chosen system has been rigorously tested and officially certified.

All of our systems are fully tested and certified in UK laboratories, and full test reports for each of our products are freely available. The acoustic tests are conducted on full-height, multi-module screens with glazing joints and perimeter track-work; not simply a ‘window’ in a smaller-sized opening. Testing samples using the latter method will generally give an artificially higher acoustic rating and therefore clients should treat any results obtained in this way with great caution.

Exceptional Sound Insulation Performance

We have a thorough understanding of our market and an appreciation that each of our clients has a unique set of requirements. We offer expertise in acoustic design and Research and Development, with an experienced team providing the best in glass partition acoustic advice. Our products have been meticulously created with our client’s needs in mind.

We recognise that our clients want and need exceptional performance when it comes to acoustic sound insulation within office environments. Therefore, with the ongoing requirements for predominantly open plan office space, there is a growing need for quiet offices and meeting rooms with controllable acoustics for confidential conversations or private working. With this in mind, we have made significant investments to ensure we provide glass partitioning solutions that offer exceptional sound insulation. 

At Optima, we focus on delivering outstanding acoustic performance across our range of glass partitions and doors. With this in mind, it is crucial for our doors to perform acoustically too, so we can offer complete systems that are carefully designed, expertly engineered and rigorously tested. 

Exceptional advances in our door-sealing technology reinforces our position as leaders of the glass partition Acoustic Revolution. These key developments enable us to provide glass doors that achieve similar acoustic performance to bespoke timber door sets. This complete product package combined, with outstanding installation techniques, ensures that we are at the forefront of the industry.

Our award-winning products are what set us apart; our installations reinforce the difference, and our service and support make us incomparable. We shaped this industry, and as we continue to make ground-breaking developments in the acoustic performance of our glass partitions, we are proudly leading the Acoustic Revolution.
