Roofing barrier TOP 3

To achieve and maintain an optimal thermal insulation of the roof, the full height between the rafters should be used. The best solution will then be the direct application of the "underlayer" on top of the insulation and fixed to the rafters. For this function the materiel has to satisfy certain quality requirements. Only complete waaterproof properties will protect the insulation from the external weather conditions and only high diffusion properties will prevent the condensing of rising moisture inside the insulation. Satisfying these two basic requirements ensures a dry roof with a long service life. High diffusion Accumulated daamp and moisture in the building will eventually find its way up into the roof construction. Condensation of moisture in the construction can only be prevented through a vapour open under-layer - allowing the moisture to pass through, keeping the roof dry. Safe as safe can be The very high tear resitance of the materiel ensures an easy and safe application. Even if the hard roof covering gets damaged Isola Top 3 still maintains a diversion function that allows rain water to drain away down to the gutters at the eaves.
