This test used a measured number of designated bacteria and measured the kill rate over a 24-hour period.
ISO 21702:2019 Viral Growth Test
99.8% Reduction in SARS-CoV-2
This test used a measured number of SARS-CoV-2 virus and measured the kill rate over 24 hours.
UVC Light Ray Exposure
900 Hrs. Passed With No Change
CoilSafe Plus was exposed to UVC, and pencil harness and adhesion were tested every 200 Hours, with no change in the performance noted.
ThermalBlock™ (or ThermalBlock by Coat Zone™) Testing
ASTM C1549 Reflectivity Testing
Rating of .89 Achieved
This test places a sample in a light chamber and measures the percentage of visible light that is reflected off the surface. ThermalBlock™reflects 89% of visible light.
ASTM C1371 Emissivity Testing
Rating of .87 Achieved
This test places a sample in a chamber and measures its resistance to heat gain from heat sources, such as air temperature and IR heat gain. ThermalBlock™ rejects 87% of heat gain from external sources.
ANSI/UL 723 Flame and Smoke Spread
Flame Rating of 5, Smoke Rating of 20
This test used ThermalBlock™ applied to a cement board and then subjected to a metered flame at a specified temperature and duration. With a flame rating of 5 and a smoke rating of 20, ThermalBlock™ is a tier 1 material and highly resistant to flame or heat.
Solar Reflective Index
Low Wind: 108.0
Medium Wind: 108.24
High Wind: 108.46
Achieved an SRI of 108 across varying wind conditions, indicating excellent solar reflectivity and heat resistance properties.
ASTM D882 Tensile strength
Rating of 5,374 psi
This test is conducted by using and prescribed thickness of ThermalBlock™ and applying a stretching pressure until the break point of the ThermalBlock™
Formaldehyde Test
<10ppm
Measured formaldehyde levels were below 10ppm, confirming the coating’s safety for indoor air quality.
Volatile Organic Compounds (VOC) Test
Rating of 30% Expansion/Contraction
This test was conducted by UL Labs to determine the overall strength and the expansion and contraction abilities of the product. The results are excellent and show that ThermalBlock™ is a very durable product that will stand up over time.
ASTM D882 Elongation test
Rating of 30% Expansion/Contraction
This test was conducted by UL Labs to determine the overall strength and the expansion and contraction abilities of the product. The results are excellent and show that ThermalBlock™ is a very durable product that will stand up over time.
NFRC 201-2017 SHGC Test
93% Reduction of Heat Transfer
Performed by Intertek Solar Labs. Test showed an 83.63 w/m², 93% reduction of heat transfer through the coated surface and a SHGC improvement from .09 uncoated versus .01 for a coated surface.
Thermal Conductivity Test
K- Value: 13% Reduction
R-Value: 20% Increase
The test was conducted per ASTM C518-21, the coating reduced thermal conductivity by approximately 13%(K-Value) and increased thermal resistance by around 20%(R-Value) when applied to cement boards.
ASTM D3359 Adhesion Testing
Rating of 5A/5B
This test is conducted on a sample to determine how well it adheres to the surface and to determine the durability of the bond to the surface. 5A/5B are best-in-class ratings and are two tests conducted with an X cut on the surface and a cross-hatch cut on the surface. With these results, we have an extremely good bond and long life of Thermax bonded to a surface.
K-Value/
R-Value/U-Value
K-Value: 0.1775 W/mK
R-Value: 0.0485 m2K/W
U-Value: 21.37 W/m2K
The thermal conductivity (K-value) of the cement board is 0.2048 W/mK, which improves to 0.1775 W/mK with ThermaBlock™. Correspondingly, the thermal resistance (R-Value) increases from 0.0405 m2K/W to 0.0485 m2K/W, indicating enhanced insulation. As a result, the thermal transmittance (U-Value) decreases from 24.69 W/m2K for the uncoated board to 21.37 W/m2K with the coating, demonstrating improved energy efficiency.
ASTM D3363 Pencil Hardness Test
Rating of 4B
This test is conducted on a coated sample by using specific pencils with varying lead hardness, and the pencil is drawn across the surface to determine at what point it will scratch the surface. 4B is a mid-range hardness and demonstrates resistance to medium traffic and abrasion.
ASTM C1549 Reflectivity Testing – 3 Year
Rating of .80 Achieved
This test places a 3-year-old sample in a light chamber and measures the percentage of visible light that is reflected off the surface. ThermalBlock™ reflects 80% of visible light.
ASTM C1371 Emissivity Testing – 3 Year
Rating of .87 Achieved
This test places a 3-year-old sample in a chamber and measures its resistance to heat gain from heat sources of air temperature and IR heat gain. ThermalBlock™ rejects 87% of heat gain from external sources.
