Abstract
A transparent substrate (i), particularly glass, having a stack of thin films comprising successively form the substrate: PA1 i) a first dielectric material film; PA1 ii) a first film having infrared reflection properties; PA1 iii) a second dielectric material film; PA1 iv) a second film having infrared reflection properties; PA1 v) a third dielectric material film; PA1 vi) a third film having infrared reflection properties; and PA1 vii) a fourth dielectric material film, wherein the thickness of said third film having infrared reflection properties (vi) is greater than the thickness of said second film having infrared reflection properties (iv) and the thickness of said second film having infrared reflection properties (iv) is greater than the thickness of said first film having infrared reflection properties (ii).
