The “TOP” DRAIN with mechanical fixing is one of the best systems for connection to rain pipes.
It is particularly suitable for use on roofs with minimal slopes, under roof gardens, “inverted roofs” and tiled terraces.
The coupling and fixing with waterproof membranes is done mechanically by means of a screw ring, this system allows use with all types of waterproof membranes, from thermo-welded roofing felt, through PVC, EPDM foils, to TPO and others.
If you are interested in installing a drainage system on flat, inverted or green roofs, as well as terraces, our TOP roof outlets are the perfect solution.
