Enviroclad (TPO) Waterproofing Membrane
Description

Viking Enviroclad offers absolute watertight integrity for low-slope roofs. It is a TPO (thermoplastic polyolefin) waterproofing membrane rendering all the necessary attributes of a world-class system, from waterproofing to aesthetic and environmental elements.

Viking Enviroclad has been a proven performer. It has been tried and tested both internationally and locally, having been installed on thousands of buildings and homes across New Zealand and the Pacific Islands since 2007.

Viking Enviroclad is not just a membrane, it is a 'system'. It is not complete without its compatible adhesives, sealants and proprietary weldable accessories; all internationally lab-tested, proven and supplied by the one manufacturer in the USA.

Roofs with an air conditioning unit, tricky corners, or pipe penetrations are the areas most prone to potential leaks if not managed properly. Viking Enviroclad's heat-weldable accessories have been developed to ensure water tightness in these vulnerable areas. These accessories range from heat-weldable internal and external corner flashings, to self-sealing pourable pockets to create a watertight finish around penetrations.
