The Pro Clima SOLITEX MENTO Difference

The Pro Clima SOLITEX MENTO Difference

Pro Clima's exterior weather resistant membrane (WRB) and roof underlayment (the SOLITEX system) incorporates a monolithic TEEE* film. This membrane, unlike conventional WRBs, has no pores and is completely waterproof and wind/airtight. This material actively transports the vapour outward by passing it along its molecular chain of monolithic membrane (see image above) - a property of the TEEE material. Therefore, if vapour/water is present on the interior of the membrane, even the slightest vapour pressure differential (inside to outside) will engage the chain reaction and dry out the water/humidity. Consequently, the membrane, unlike conventional housewraps, is very vapour open (38 perms, Sd-value 0,05m) in every condition. Conventional housewraps and WRBs depend on creating a micro-porosity in a normally vapour closed material (PE or PP). In the production process these materials are made vapour open by either spunbonding them into a PE mesh, puncturing the PP or stretching the PP with NaCi additives in production. These micro-pores then allow water vapour molecules to be moved through the water-resistant layer by convection (leaking through the micro-pores).
