1. R-value is a measure of an insulating material's resistance to heat transmission . 2. "Low-emissivity " windows look as transparent as regular glass but reflect infrared light, reducing heat transmission . 3. It was thought that the water on the roof would decrease heat transmission through reflection and evaporation. 4. Here, the low emissivity of aluminium does work with the air above and below it to lower heat transmission . 5. This slows the heat transmission through the walls, but it has little effect on heat loss through the ceiling. 6. Some models of nonlinear heat conduction ( which are also parabolic equations ) have solutions with finite heat transmission speed. 7. These two properties very good heat transmission and low pressure loss provide an advantage in terms of energy saving. 8. R-value is a measure of an insulating material's resistance to heat transmission : the higher the value, the more effective the insulation. 9. R-value is a measure of an insulating material's resistance to heat transmission : The higher the value, the more effective the insulation. 10. Thanks to the size of the particles ( ~ 5nm ), surface plasmons on the metallic particles are generated and enable the heat transmission .
