Concept

1. Ultra-violet rays constitute 5% of sunlight. This causes photo-degradation of organic matter.
2. Visible light constitute 43% of sunlight. Different visible colours are detected by the human optical system.
3. Near infra-red rays constitute 52% of sunlight. Heat is the output of infra-red radiation on any object.

Thermacool Coating reflects the heat producing infra-red part of the sun light back into the atmosphere. Two coats of Thermacool Coating forms a thermal reflecting heat barrier, with 100 micron thickness.

Due to the reflectance of about 89% of the IR Solar Radiation absorbed by the IR sensitive additives in the paint have a tremendous drop in the roof temperature (15 – 20°C for an ambient temperature of 40 – 45°C)
Also. Thermal insulating materials in Thermacool Coating provides significant insulation from the heat penetrating into the surface.

• Day temperature recorded at 42°C
• Very high surface temperature at the rooftop at 60°C
• High ceiling temperature below the roof at 48°C
• Difficult working conditions inside the warehouse at 45°C

• Day temperature recorded at 42°C
• Tremendously reduced surface temperature at the rooftop at 48°C
• Significantly lesser ceiling temperature below the roof at 40°C
• Comfortable indoor temperature inside the warehouse at 38°C

Thermacool is a high performance, exterior surface coating with excellent infra-red heat reflection properties. The primary benefit is 15°C to 20°C reduction in roof top temperature, depending on the hot summers. Thermacool Coating is a patented product, uniquely designed and developed by Indian Institute of Technology, Bombay.
