Edge Series

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, along with Edge Flush, a stunning flush, frameless double glazed door leaf for use within any of the popular Microflush door frames across the Optima glazed partition range. Not only are these doors beautifully designed, but they can also perform as well acoustically as bespoke acoustic timber door sets,

Glass Doors Features

Edge Symmetry

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.
