Waterproof Membrane Supply.

Our EPDM Waterproof Membrane
Our EPDM waterproof membrane comes in 2 widths. Please calculate the total length of each width / widths you require and enter the length in the relevant box. Please note the waterproof membrane may only be purchased in full metres. When calculating the total size you require you should allow an overlap of 100mm between two different pieces of membrane and an overlap sufficient to cover any installed retention battens or enough to cover your specific design at roof edges. A standard roof edge detail would allow for 100mm overhang.
