   Caculated according to construction energy-saving system,when sun reflectance and hemisphere reflectivity reach 0.80, reflection heat insulation coating has the special insulation property.For example,in Nanjing’s weather, when sun reflectance and hemisphere reflectivity is 0.80,equivalent coating thermal resistance(0.16-0.20) is M2K/W;In Guangzhou’s weather, when sun reflectance and hemisphere reflectivity is 0.80,equivalent coating thermal resistance(0.15-0.28) is M2K/W.

   Material comparison

Ratio between Building reflection heat insulation coating and other heat preservation materials

	Building reflection heat insulation coating	other heat preservation materials
Economical	Low-cost,low-process	High coat,complicated construction process
Environmental	Low VOC non-toxic water coating	Nondegradable,high diposing cost
Energy-saving	Low nonrenewable energy	High consuming of nonrenewable energy such as fossil oil
Decorative	Alternative color,and good quality	Need other decorative means
Safe	safety	Flammable,cadicous,potencial safety hazard
Perdurable	Long time high-class coating and no safety hidden danger	Cadicous,slack,potencial safety hazard
Protection	Protective and repaired function	Simple covering function,non safety hazard
Renovate cost	Low renovate cost,need building insulatin coating	High renovate cost,firstly,chisel old grass root,complex disposing old grass root,then renovate thermal insulation materials
Renovate construction period	Easy disposing of the old coating	Long construction of renovating,need chisel old grass root,have big influence to the owners
