Low vapour permeability membranes

The KF low permeability membrane has found its application as an initial roofing layer in building with habitable as well as non-habitable loft spaces. The low permeability membrane proves to be a very effective insulation of walls in buildings of skeleton structure (wooden or metal). In buildings in which function and simple roof shapes do not require application of membranes offering high vapour permeability and, at the same time, high strength and low material costs play major role, the low vapour permeability membrane can be used.

The EUROFLEX system is used for anti-moisture insulation of foundations, terraces, ceilings, roofs and floors. With special embossed areas, it forms a gap to allow additional ventilation of insulated surfaces.

The system consists of:

• EUROFLEX 400 foundation dimpled membrane
• EUROSLAT finishing slats
• EUROFIX mounting connectors

The non-permeable underlay used in conjunction with EUROTOP high vapour permeable membranes makes it possible to retain proper climatic conditions within the habitable loft spaces. This product range includes two types of non-permeable underlays: Termofol 90, 115 and Eurotop Activ V110. The Termofol 90, 115 is a non-permeable underlay with a reflective layer that provides very effective protection against water vapour penetration into insulation and, thanks to a thin layer of aluminium film used, it partially reflects the heat radiating from the loft. The Eurotop Activ V110 is an active non-permeable underlay allowing vapour to flow inside and outside the room in controlled volumes, resulting in better drying of the roof. The Eurotop Activ V110 can also be used as a wind insulation in ventilated walls when installed on the outer side of the partition.
