External door | LV 965 AL The fully transparent door The fully transparent high-speed door LV 965 AL is suitable for high ingress of light as an outside door but also for an improved view in internal areas. The 4 mm thick transparent curtain lets light into the room resulting in a pleasantly bright workplace. When used as an external door, we recommend the heavy transparent version. The routes of transport are made safer as a result of the free field of vision, also from far away. Along with the tensioning system fitted as standard, the spring steel wind locks provide the required curtain stability.
