Mulseal
The ideal bitumen/rubber latex emulsion
provides a waterproof sandwich membrane with an indefinite life
The roof, often the largest area of uninterrupted surface in a building, can be subjected to considerable thermal expansion and contraction as temperatures change from night to day and from season to season. Therefore, it is vital particularly in territories where such variations of temperature are wide and rapid-that the waterproofing membrane of the roof be highly elastic. It must also be capable of retaining this elasticity over long periods.

Treated in this manner, the membrane can be considered as possess- ing an indefinite life since it is protected not only from the elements, but also from ultra-violet light, the prime agent of deterioration.
