Application

EXOPERM MONO DURO 200 is an external breather membrane designed for use on the cold side of insulation on façade wall and roof applications.

Suitable for:

Rear ventilated facades, with open or closed joints
Timber and steel framed constructions
Warm, cold and hybrid roof applications
Pitched or flat roofs
Sarking boards

Monolithic Technology

EXOPERM MONO DURO is a 2-Ply sarking, roof underlay and wind barrier with next generation monolithic functional layer.

The monolithic functional layer provides enhanced protection for the building envelope:

transports vapour to outside
is vapour open whilst having excellent waterproofing properties
creates a complete wind tight, waterproof membrane that actively expels out any water/humidity unlike most micro-porous membranes that rely on small pores (which have the tendency to block)
