VENTILFLEX® RKV

The subject of the EPD is a liner material which is to be used for renovating ducts.The liner is made of glass fibre reinforced thermoset composite material. The glass fabric is impregnated with a resin mixture containing additives. The impregnated material is then heat-treated to reach a semisolid state intermediate product. The liner is produced from this intermediate product by folding the layers onto each other. It is packed and shipped in this semi-solid state as flat hoses for installation to trained installers. Liner is placed into chimneys, ventilation ducts or rainwater drains to be relined, inflated and hardened (final polymerization) according to the technology. Kompozitor provides liners only to trained and certified professional installers who are in possession of the know-how and own special technological equipment.
