GRA methane barrier
Loose laid methane resistant membrane.
A loose laid 20 micrometre pure aluminium substrate with a multi-filament polyester 20 mm scrim grid, sandwiched between two layers of polyethylene to offer a high resistance to puncture and to ground contaminants.
Alumasc Timloc GRA remains flexible and does not soften at extremes of temperature likely to occur in practice.
