CERAMIC HEAT BARRIER COATINGS
A passive investment towards improved control over energy
costs
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
Solving the problem
More efficient equipment Introduction of renewable energy sources Improving insulation Reducing energy needed for heating and
cooling Applying energy management
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
BASIC PRINCIPLES
Technology
Insulation materials Inverters, timers, friction reduction, direct
drives, etc. NASA development for space craft Nano technology Ceramic Heat Barrier Coatings
Millions of hollow ceramic spheres in an acrylic binder
Dead Air
40 µm ø
Pure acrylic binder with rust preventing and anti-fungal agents – white titanium dioxide
pigment
500 µm wft
325 µm dftCHBC
Product Composition
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
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
35 ⁰ Cambient temp.
Internal Heat Load
Reduction from 176 to
132 watts/sq.m
80% Reflectivity 20% Emissivity
Galvanised Steel Roof Sheeting0,5 mm thick
Coated with 500 µm wft CHBC
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
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
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
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
Conclusion
It pays to install a Ceramic Heat Barrier Coating
