Within the context of preventive fire protection, floor drains with vertical outlets are regarded as pipe/ceiling feed-throughs that require sealing off. With its tool-free fire insulating structural elements, Dallmer has created the ideal solution. These fire insulating elements have an intumescent lining that swells up when exposed to a temperature exceeding approx. 150°C. The volume of the material increases approx. 15/20-fold and seals off the ceiling feed-through quickly, reliably and safely, thus preventing the spread of any heat, flames or smoke via this feed-through.
The assembly system includes a sound insulation collar that separates the drain body from the main building structure, thus preventing any structure-borne sound.
