SOPRAGUM OPTIMA 4 C
SOPRAGUM OPTIMA4 C is used as a single-ply waterproofing membrane or as an upper layer in a multi-layer system.
Waterproofing membrane composed by APP modified bitumen with a composite polyester reinforcement which results in a better dimensional stability and mechanical resistance. The reinforcement is impregnated with an APP compound. The homogeneity between the covering mass and the impregnation compound results in an extremely high resistance to delamination. The upper side is finished with mineral slates or sand/talcum. The selvedge is protected with a popypropylene film. A torch-on film protects the lower side (torch-on method) or sand/talcum (cold glue).
