TOPIC stop rails are equally ideal for new or renovated buildings. In addition the threshold height is designed to be suitable for handicapped people. The TOPIC stop rail is made of glass fibre reinforced plastic with kick-resistant fabric inlays. As a result of the carefully thought-out design of the TOPIC stop rails, the door leaf has two seals in the critical lower segment, which ensures additional heat insulation. A further advantage is that no cold bridges are formed. This prevents the seals from freezing even in extreme weather conditions.
