Sim-II Double Carrier Membrane

Sim II Membrane is a bitumen water insulation cover with double polyester felt carrier which has high resistance ability.

It is especially preferred for strong and moving buildings such as heavy industrial structures, multi-storey car parks carrying movable loads, bridges, art structures, airports, stadiums, supporting walls and canalettes etc.


It provides resistance against high tensions with two separate carriers included in its structure. We use thermoplastic resinous atactic polypropylene (A.P.P.) in such bitumen membranes in order to increase bitumen’s durability. These membranes are produced in 3mm, 4mm and 5mm thick, 1m wide and 10 m long rolls.
