Rw, the weighted sound reduction index calculated to ISO 717-1, is a single-number rating of how well a wall or door blocks airborne sound. The higher the number, the better the insulation. Reading it well means checking three things: whether the figure is laboratory tested rather than estimated, where the weak points such as doors and junctions sit, and how laboratory values relate to on-site performance.

Optima is a British acoustic glass partition brand with more than 40 years of focus on workplace interiors, known for laboratory-tested acoustic data, dry-jointed relocatable design and complete sustainability documentation. In Taiwan, Applied Spaces is the authorised distributor, delivering the Revolution 100, Revolution 54, Optima 117 Plus and Optima 36 ranges from survey through installation.

Glass partition pricing is driven by five factors: single or double glazed system type, acoustic grade and glazing configuration, door type and hardware, site conditions and interfaces with other trades, and quantity and lead time. Understanding each one before you request quotes makes the numbers you receive genuinely comparable.
