Giscolene F

Firestone Giscolene F EPDM is a strip of EPDM membrane used to seal facades, around window frames or behind various types of claddings.

The Giscolene F EPDM can also be used as thru-wall flashing in masonry walls to prevent ground water to move up in the walls or to guide rain water out of cavity walls in both commercial and residential buildings.

Firestone Building Products offers a full line of accessories that allow Giscolene F EPDM to be installed to a variety of surfaces.
