Mapethene HT is a 60-mil, self-adhering sheet membrane consisting of 56 mils of rubberized asphalt laminated to a 4-mil, cross-laminated polyethylene film. The combination of these two excellent waterproofing materials provides a durable, high-performance waterproofing membrane. Mapethene HT membrane is suitable for installations where the ambient and substrate temperatures are above 40°F (4°C). Mapethene LT is designed for ambient and substrate temperatures between 25°F and 60°F (-4°C and 16°C).
