The SFL Seldek Flashing system has been developed to compliment the wide range of SFL Chimney and Flue products. Seldek Flashings consist of a base manufactured from a soft and malleable aluminium, to which an EPDM (Ethylene Propylene Diene Monomer Polymer) flexible cone is secured. The EPDM cone is black. Some of the illustrations in this leaflet show the cone to be a lighter colour for technical reasons. The cone is marked to provide an index of cutting grooves identified for different external diameters, and Installation Instructions and compatibility information is provided with every Flashing.
