The 3×3 approach to how cool insulation coatings work
Insulation coatings like these are engineered to block heat either by not letting heat escape or by blocking entry, or both. This is done with special resins and additives added to the base coating. This is found in the window coating.
Often additives such as hollow microspheres made of materials like glass, ceramic or thermoplastics are used to form tiny air pockets in the coating. This reduces heat gain through conduction.
Sometimes other additives are used to reflect certain light spectrums. My best coating deflects all three sections of the heat spectrum – UV, visible and infrared, for a total of about 95% of the sun’s radiant heat.
Other coatings focus on either the IR or visible/UV sections, but not all three.
A tight coating structure keeps out bulk water but allows moisture to escape. This semi permeable design does the same for air.
Top coatings act as an air and vapor barrier, like what you might find in new construction. But they also emit 90%+ of the heat they do absorb. Heat movement through radiation, conduction and convection is reduced while blocking UV, visible and infrared light. A 3×3 approach to heat management.
