Metalized Pipe Lagging is made of 100% closed-cell polyethylene foam. It has a low water vapour transmission rate making it excellent in insulating both cold and hot water pipes. Metalized Insulation Pipes are used to insulate pipes against heat gain or lose and prevent condensation on cold water plumbing and has an operating temperature of between -40°C and +95°C. Its closed-cell structure allows it to reduce unwanted heat loss or heat gain, decrease plumbing noise, prevent condensation and corrosion and maximizing energy saving.
