Petroleum or natural gas is processed to produce ethylene and chlorine is derived from salt.
Both membranes are heat weldable which makes them more resistant to leaks than epdm because of a reduced number of instances of seam failures.
The seams are either glued with the rest of the roof different process same result or they are taped.
Tpo and pvc both have welded seams which are very strong.
Membrane roofing is designed to move water off the roof and poses a unique advantage to previous methods of flat roofing which usually consists of asphalt or gravel.
