Maximum transparency, maximum performance

System 3500 is our double-glazed mullion-free system with glass to glass connections and minimal frames for high transparency whilst being reassuringly confidential.  Every detail is designed with acoustic privacy in mind. Just closing the hinged door instills confidence in the solidity of the design.


The slim profiles, direct glazed door frame and elegant head deflection detail create a visual counter balance to the high performance double glazing.


Ultimate performance - Rw47dB with an Rw 44dB door gives unprecedented acoustic isolation. Alternative glazing options are available to tailor performance giving flexibility across a project.

The anodised finish captures the beauty of metal bringing out the soft sheen of the base material. Particularly complimentary to timber veneers. Available in six colours to give design freedom.

Strähle precision mitred glazed corners and T-junctions are a signature feature and visually reduce glazing joints to a hairline delivering a clean elegant detail.
