Product Data and Performance

Monarflex Reflex Super radon barrier membrane comprises 6 individual layers. These include 4 layers of virgin low density polyethylene (LDPE) film, a 12 x 12mm multi-filament polyester (1670 dtex) reinforcing grid and a 12µm aluminium foil layer. The all-important aluminium layer is what gives Reflex Super its exceptionally high gas resisting properties. It is sandwiched carefully between two layers of polyethylene for extra protection. Monarflex Reflex Super should be used in conjunction with Alumite Gas DPC.
