The Comprehensive Comparison of Thermal and Physical-Mechanical Properties of the Recycled Rubber and Plastic Roofing Tiles versus Roofing Tiles Made with Different Traditional Materials

Table 4

Thermal transmittance coefficients, K, for different types of house cover.

Type of house cover	IRAM Norm (winter design temperature = −4.3°C)			K calculated for each case (W/m^2K)
	A	Sugerido	B
	0.28	0.50	0.72
(1) With zinc sheets	It verifies level B			0.725
(2) With ceramic roofing tiles	It verifies level B			0.71
(3) With concrete roofing tiles	It verifies level B			0.72
(4) With roofing tiles made from recycled rubber and plastic	It verifies level B			0.70
