*INSUL-LOCK速 II in thickness noted within the specified temperature ranges will prevent condensation in indoor piping under design conditions defined below.
Thickness recommendations above 1" can be sleeved to achieve thickness desired.
Normal: Maximum severity of indoor conditions seldom exceed 850属 F and 79% R.H. in United States.
Mild: Typical conditions are most air-conditioned spaces and arid climates.
Severe: Generally found in areas where excessive moisture is introduced or in poorly ventilated areas where the temperature may be depressed below the ambient.
Under conditions of high humidity, additional thickness of insulation may be required.
