Pioneering Advances in Insulated Glass Technology
Our Story and Commitment
OKALUX has, for over 60 years, been an innovator in the production of insulated glass units that incorporate inserts in the cavity to offer improved daylighting and solar control with elegant and striking visual appearance.
In February 2020 OKALUX GmbH was purchased by BGT Bischoff Glastechnik AG in Bretten, now part of the GlasTrösch Group of companies, and the new company OKALUX Glastechnik GmbH was established. Continuing to produce its products out of the factory close to Marktheidenfeld in Germany, the new company remains a one stop shop for your project glazing requirements .
While operating independently within the group, OKALUX Glastechnik GmbH can draw on the wide portfolio of additional products and processing skills offered by BGT Bischoff Glastechnik AG and the other companies within the Glas Trösch group.
VENA Ltd continues it’s longstanding representation of OKALUX Glastechnik GmbH and to support the work of the Glas Trösch group in supplying architectural glazing solutions in the UK, Ireland & Scandinavia.
By looking at what you want to achieve at an early stage, and working with your project team, we can assist in preparing specifications and cost planning through to the final realisation of the project.
