Notes : 1. Table is based on thickness required to prevent condensation on surfaces
with following design conditions:
Ambient temperature
: 30 C
Relative humidity
: 85 percent
Surface heat transfer coefficient: 8 W/(m2.K) [6.88 kcal/(m2.h.C)]
2. Where other design conditions are used, thickness should be adapted to
meet job requirements.
