PIB insulation covering (Polyisobutylene) is the ideal waterproofing membrane for ventilation ducting and pipework. It gives your exposed insulation and ductwork that final protective coating. This tough, water-resistant PIB insulation sheet has high abrasion resistance and can withstand mechanical damage.  It is produced from high molecular weight polyisobutylene, which is modified to achieve optimum properties.

The PIB insulation covering does not age, crack or peel. It is resistant to UV and ozone and is a long-lasting and durable product. It shows exceptional physical properties even at temperatures as low as -30°C. PIB insulation exhibits excellent chemical resistance. It is made to last and effectively protect the pipe and duct insulation from damage due to extreme conditions. It is waterproof, so it does not support the growth of moulds and other microbes.
