Heat Reflective Paint

Heat Reflective water based high thermal emittance coating useful in the world of industrial and commercial buildings, as a roof coating system that has the ability to reflect the visible, infrared and ultraviolet wavelengths of the sun, thereby reducing heat transfer to the building.

 Solar heat incident on a roof is dissipated by means of three physical phenomenon namely: 

» A fraction of the absorbed heat is conducted to the ground and surrounding buildings
» A fraction is convected to air leading to higher air temperatures, and
» A fraction is radiated to the sky.

As such one has no control over the first two phenomenon but the third one, that is, the amount of heat radiated can be maximized by using heat reflecting roof/ wall coatings that inherently possess high emittance values. Use of heat reflective coating is particularly useful where the terrace covers an air conditioned space. A higher roof temperature necessarily leads to a higher load on the air-conditioning plant a reduction in roof temperature will result in lower roof temperature with consequent savings in power consumption.

Advantages Heat Reflective Coating:
  • It reduce energy costs: - whether it's the climate outside or inside, it certainly makes sense to save every cent possible in today's financial climate, and there's no doubt that as far as house paints go, heat reflective paint help reduce heat loss, helping to conserve fuel and money even more. Why not use it to insulate your water storage tank, your pipes and everywhere else where heat loss could occur.
  • Reflecto insulating paint will cool down your roof, reflecting away up to 90% of the suns heat.
  • Ultraviolet resistant – continuous rejection of solar heat resulting in drastic reduction of roof heat
  • Protects the roof from fungus and moulds formation
  • Eliminates the formation of cracks
  • Water-based – contains no solvents, cleans up with water. No VOC.
  • Good elasticity and waterproofing capability
  • Good hardness and abrasion properties
