PROBLEM: Former insulation (perlite) became moisture laden which significantly reduced the R-Value. The result was unnecessary heat loss,  corrosion to the pipes and mold in the insulation, all due to moisture.

 

SOLUTION : Clean and primer coat pipes with RUST GRIP ® @ 3 - 6 mils WFT = 1.5 - 3 mils DFT to permanently rust proof pipes and prevent rust bleed. Top coat with SUPER THERM ® NON DETERIORATING ( waterproof  ) liquid ceramic R19 insulation @ 14 mils WFT = 7 mils DFT

Note : 1 mil = 1/000"

BELOW:  Top coat SUPER THERM ® NON DETERIORATING liquid ceramic insulation

TEMPERATURE READINGS:  05/04/01 (day of application)
Bare portion of feeder pipe                 = 80C
SUPER THERM ® coated feeder pipe  = 76C
Temperature Difference                       = -4C (5% REDUCTION IN HEAT LOSS)
Bare portion of return pipe                 = 49C
SUPER THERM ® coated return pipe  = 46C
Temperature Difference                     = -3C (6% REDUCTION IN HEAT LOSS)

NOTE : During the initial reading the coating of SUPER THERM ® which cures by evaporation still had moisture in the coating which acted as a conductor as opposed to a resistor ( R ). SUPER THERM ® contains 8% water when first applied. The Canadian Roofing Association performed a study and determined that just 1% - 1.5% moisture content reduces the R value in bulk insulations by over 35%. As the coating of Super Therm cured down and the moisture content decreased the performance improved.

Bare portion of feeder pipe                 =   86.2C
SUPER THERM ® coated feeder pipe  =   69.8C
Temperature Difference                      =   16.4C (19% REDUCTION IN HEAT LOSS)

 

Bare portion of return pipe                =    41.3C
SUPER THERM ® coated return pipe =    33.5C
Temperature Difference                    =       7.8C (19% REDUCTION IN HEAT LOSS)

NOTE : A greater reduction in surface temperature can be achieved by adding additional mils.
