Ceramic Heat Barrier Coatings

1. Ceramic Heat Barrier Coatings A passive investment towards improved control over energy costs

2. Underlying Problem • Controlling the temperature inside a building • Energy costs escalating • Most existing buildings not energy efficient • Retro fitting can be costly • Equipment replacement costly • Must reduce energy consumption • Maintenance influence energy consumption

3. Solving the problem • More efficient equipment • Introduction of renewable energy sources • Improving insulation • Reducing energy needed for heating and cooling • Applying energy management

4. Basic Principles • Many sources of heat: • Equipment, people, sun • Heat moves towards cold • Heat transfer via conduction, convection and radiation • Radiation is a major element • Reflection • Emissivity

5. Basic Principles

6. Technology • Insulation materials • Inverters, timers, friction reduction, direct drives, etc. • NASA development for space craft • Nano technology • Ceramic Heat Barrier Coatings

7. Product Composition 500 µm wft CHBC 325 µm dft 40 µm ø Dead Air Millions of hollow ceramic spheres in an acrylic binder Pure acrylic binder with rust preventing and anti-fungal agents – white titanium dioxide pigment

8. Effect • Reduction in radiated heat transfer • From outside to inside when coated on outsides • From inside to outside when coated on insides • Reduction in conduction due to reduced radiation • Reduction in thermal stress for substrate • Reduction in energy consumption to regulate temperature

9. Typical Uses • Outside of walls and roof • Inside of walls and ceiling • Piping for steam • Ducting for air conditioning • Equipment heat shields • Warehousing spaces • Tanks and storage vessels • Load boxes of vehicles

10. Galvanised Steel Roof Sheeting 0,5 mm thick Coated with 500 µm wftCHBC 35 ⁰ C ambient temp. 80% Reflectivity 20% Emissivity Internal Heat Load Reduction from 176 to 132 watts/sq.m

11. Benefits (1) • Reduces interior heat of buildings by up to 45% • Save electricity by using less air conditioning and refrigeration • Greater indoor comfort during hot weather • Greater indoor comfort during cold weather • Stops thermal ageing by reducing heat load • Insulates roofs at a fraction of the cost

12. Benefits (2) • Prevents rust, eliminates blistering, peeling & cracking • Eco-friendly as it reduces dependence on electricity • Easy and quick low-cost application • Insulates hot surfaces to provide improved safety • Is non toxic and therefore does not harm the environment • Is rust and mildew resistant • Repels moisture

13. Benefits (3) • Easy to clean with soap and water • Abrasion resistant • Flame resistant • Can be used on a wide variety of surfaces • Long life without degradation • Can be applied in tight spaces where access is problematic • Accidental blemishes can easily be repaired

14. A passive investment • Cooling load reduction = lower energy costs • Heat load reduction = lower energy costs • Improved corrosion protection = lower maintenance cost • Reduced thermal stress = lower maintenance cost • Wear and fungus resistance = lower maintenance cost • Most payback periods less than 24 months • Economic life of coating at least 10 years
