Viking Gemini APP is a robust and versatile membrane system ideally suited to New Zealand's North Island (except the Central Volcanic Plateau) and the Pacific Islands.
Viking Gemini APP consists of a 3mm thick base sheet installed on a bitumen-primed substrate. This provides a building's secondary waterproofing layer, on top of which a 4mm ceramic chip cap sheet is then 'torched' to provide the primary waterproofing and UV resistant layer.
