NOMALOCK® is used to retard heat gain and prevent condensation or frost formation on cold water plumbing, chilled-water and air conditioning lines. NOMALOCK® also retards heat loss on hot water plumbing. NOMALOCK® has a low thermal conductivity and very low water vapor transmission rate. This low density product demonstrates excellent thermal, physical and chemical resistant properties and has a broad service temperature range between -330°F and 210°F (-201°C and 99°C). It can be installed in commercial, industrial and residential insulation projects. Acceptable for use with heat tracing/heat tape.
