Doors have traditionally been the Achilles’ heel in any glass partition’s acoustic performance because it is so difficult to effectively seal a closed door. Glass doors in particular are poor performers where acoustics are concerned. But all that has changed thanks to Optima’s considerable investment in research and development, and our determination to design a range of doors that tackles this perennial problem head on. The result? The Edge Series of acoustic glass doors.
Our Edge Series features two striking framed glass doors, namely Edge Symmetry and Edge Affinity. Not only are these doors beautifully designed, but they can also perform as well acoustically as bespoke acoustic timber door sets,
The hugely popular Edge Symmetry door is a framed single or double glazed acoustic glass door which offers excellent acoustic performance. Ideal for offices and meeting rooms requiring a high level of acoustic privacy, Edge Symmetry can achieve a maximum acoustic rating of Rw41dB in its double glazed form.
This elegant door is designed for use within our Microflush door frame and can be hinged or pivoted. Edge Symmetry features a slim 30mm standard width stile at the leading edge; 18mm visible on the corridor side when the door is in a closed position, If a lock is required it can be a dead lock, sash lock or latch. Single or paired doors are available and the maximum door height is 3000mm.

The Edge Affinity door is a framed acoustic glass door which offers outstanding acoustic performance. With superior perimeter seals, the Edge Affinity door can achieve Rw39dB in single glazed form and Rw42dB in double glazed form.
The door features a 78mm wide stile at the leading edge; 66mm visible on the corridor side when the door is in a closed position. The stile can accommodate a dead lock, sash lock or latch. Single or paired doors are available and the maximum door height is 3000mm.

Edge Symmetry single glazed – Rw35dB
Edge Symmetry double glazed – Rw41dB
Edge Affinity single glazed – Rw39dB
Edge Affinity double glazed – Rw42dB
