Project Description

30 year review of SUPER THERM in-field performance.

This SUPER THERM Test roof in Western Kansas was used by Daiko Shokai Corporation in Osaka, Japan to study the performance of SUPER THERM in real world atmospheric conditions over a 15 year period.  Section of the roof was removed to lab test for continued reflectivity after years of natural severe weather conditions in this part of the US. The roof was checked after 22 years but no report was written. On July 10 2019 of this year, a visit was made to check the performance of the roof with the owner of the facility and a report is now posted.

We also had one of the buildings coated with RUST GRIP (our single component corrosion protection coating to check its’ performance over years in the same climate conditions, which is below.

34 year-old RUST GRIP roof. In Western Kansas at K-Tech Facilities. Average thickness of 3.6 mils DFT Applied 5 mils DFT initially. Owner’s comment: Looks like the day we applied it.

30 year-old SUPER THERM roof in Western Kansas at K-Tech Facilities. This is the same roof that Daiko Shokai (Japanese Company) tested by cutting a piece of the roof and sending to a test lab in Tokyo to check the reflectivity of blocking heat load after 15 years and found it to be within 8% of the initial reflective performance when new.

SUPER THERM roof applied in 1989 ( 30-year old roof) at K-Tech facilities in Western Kansas facing snow, ice, extreme cold, strong storms-high winds and blowing debris and hot summers. Initial application thickness was a little heavy at 15 mils (375 microns) DFT. After 30 years, it was checked using a digital thickness gauge to read 13 mils (325 microns) loosing only 2 mils (50 microns) over a 30 year period. SUPER THERM usually repels surface heat and has a surface reading of 1degree F up to 3 degrees F above ambient temperature. The reading this day (July 10th, 2019 at 4:30pm) was 98°F (37°C) on a 90°F (32°C) ambient temperature day or only 8 degrees over ambient temperature. The uncoated metal reads 145F using a Flir heat gun. After 30 years, the SUPER THERM continues to perform by blocking the “loading” of radiation heat. Can anyone show us another insulation coating of any kind that can continue to block heat at this level after 30 years in the field?

The owner of the K-Tech facility told us that if anyone would ever want to see the facility, they could call him : Roger Kuntz at 785-673-4676.

Temperature on top of uncoated roof.

Temperature on top of SUPER THERM 47°F (8.3°C) drop in surface temperature between the uncoated roof and SUPER THERM coated roof.

Under roof , inside of office.  14°F (-10°C)drop in temperature from surface temperature of the SUPER THERM and 61°F (16°C) drop in temperature from uncoated exterior roof.

Office directly over the roof.  No standard type of insulation in walls or ceiling of the office. Only SUPER THERM is used for insulation to block the “HEAT LOAD” on the exterior roof.

Coating Solution

Letter from owner in 2000 after 11 years.

Update after 13 years.

Above report is from Japan Lab JIS comparing 21 reflective coatings to SUPER THERM performance.

The important point of this is when you read the report above, the 21 reflective coatings were only tested for 571 days (1.5 years).   SUPER THERM was tested for 15 years (5475 days) and outperformed all competition.   All Competition coatings loss 35% in 1.5 years and SUPER THERM loss only 8.1% in 15 years.

Can you see the quality performance of how SUPER THERM is designed and made compared to “any” competitive reflective coating??
