Whether designing for a flat roof in the middle of the Southern Alps or in the sunny Bay of Islands, Viking Roofspec has a BRANZ appraised TorchOn membrane system designed to withstand the most extreme climate conditions:
Viking Phoenix Super APAO (Amorphous Polyalphaolefin) Hybrid TorchOn Membrane: Viking's 'Platinum' solution incorporates the best of APP and SBS membrane features and comes with a 25 year warranty. Its unequalled cold flexibility goes down to (-35°C), and it has a high-temperature resistance of +140°C, meaning it can be used in any climate.
Viking Gemini APP (Atactic Polypropylene) TorchOn Membrane: Viking Gemini APP is a robust and versatile membrane system ideally suited to New Zealand's North Island (excluding the Central Volcanic Plateau) and the Pacific. APP membranes have a high melt point when in contact with a flame and boast some of the highest puncture resistance credentials in the market.
Viking Lybra SBS (Styrene Butadiene Styrene) TorchOn Membrane: Viking Lybra SBS is made from 'rubberised' bitumen. These properties are designed for geographical locations that experience climatic extremes, such as New Zealand’s South Island and the North Island's Central Volcanic Plateau. Viking Lybra SBS membranes have a lower melt point and high cold-flexibility credentials allowing them to be exposed to lower temperatures without fracturing.
Viking Roofspec has a team of technical and design specialists available to assist with specification. Viking Roofspec also has NZ's only established three-stage, hands-on TorchOn licensing programme to ensure work is delivered to the highest quality, to specification and most importantly is 100% water-tight.
