Halls, shopping malls, industrial plants, public buildings ... especially large roof surfaces are primarily built with a flat roof or flat-sloped roofs, as a flat roof construction has static weight advantages and thus lower costs. The waterproofing of a flat roof requires special roof sealing. Therefore Börner has focussed over decades on important topics, e.g. the UV resistance and weather resistance, the durability, fire safety and proper sealing of connectors and light domes. Formulations for polymer bitumen membranes and bitumen membranes are purposely developed for these requirements and are constantly improved.
Finally, our versatile products to seal a roof are extremely durable as well as fire resistant according to our own European patent and also meet the highest standards of elasticity and plasticity.
