JUNIFOL® membranes are manufactured from high-density-polyethylene (HDPE) and linear-low-density-polyethylene (LLDPE), using flat-die extrusion technology.
JUNIFOL® is being produced in two basic widths – 5.1 m and 8.0 m ; the thicknesses offered range from 0,6 mm up to 3,0 mm. There are three types of surface available – both sides smooth, one side structured, or two sides structured.
The product can be manufactured as a mono-layer membrane, alternatively as a co-extruded multi-layer sheet. JUNIFOL® is supplied in black colour (the standard coloration), various other colour modifications are available upon request.
Due to high quality raw materials used in the production plus a long-lasting and vast experience of our highly qualified personnel uniting in the finished product, our JUNIFOL® membranes represent a reliable insulation solution for a wide range of engineering projects and installations. Our HDPE and LLDPE based membranes offer an excellent chemical resistance, exquisite mechanical & hydraulic properties, they also represent a superb barrier against micro-organisms, fungi and root penetration; a high level of gas (e.g. methane, radon) impermeability is likewise provided. JUNIFOL® membranes are UV-stabilized as standard.
JUNIFOL® membranes are manufactured in two modifications – geosynthetic barriers (geomembranes) or sheets for waterproofing (in either case, the production process complies with all relevant harmonized EU standards, both product types bear CE marking).
For exports to European and overseas markets alike, JUNIFOL® membranes meet the demands of numerous national quality management systems (BAM, ÖNORM S 2073, ASQUAL, KIWA, BECETEL, DIBt), and the product’s characteristics also fulfill the requirements of GRI-GM13 and GRI-GM17 quality standards.
Parameters of JUNIFOL® membranes meet the requirements imposed on plastic materials intended for direct permanent contact with cold drinking water.
