PASSIVE PURPLE - Radon Red Edition® - Airtight Liquid Vapour Control Membrane

An ideal solution to prevent radon gas from entering construction from the ground up. The membrane will also act as a damp-proof membrane to protect the building against moisture that may also rise from the ground. Furthermore, the airtight radon membrane helps to conserve energy internally, saving you money whilst improving your air quality.

Passive Purple is a VOC-free water-based product. It’s completely free of any nasty chemicals or fumes. As a water-based product, cleaning your paintbrushes and airless spray device is a smooth, no mess task.
