1. An insulating double-glazing having a light transmission (TL) between 60 and 70% and a solar factor of 0.32-0.42, and a color in external reflection in the blues or greens, which comprises:
- a) a first layer, and b) a second layer, which is a transparent substrate having multiple thin layers, comprising successively;
i) a first dielectric layer on said substrate;
ii) a first layer having infrared reflection properties on said layer i);
iii) a second dielectric material layer on said layer ii);
iv) a second layer having infrared reflection properties on said layer iii); and
v) a third dielectric material layer, wherein a thickness of said first layer having infrared reflection properties is 60-70% of said second layer having infrared reflection properties.

Abstract
An insulated double glazing having the following layers in the following order: first dielectric layer, first layer with infrared reflection properties, second dielectric layer, second layer having infrared reflection properties, and third dielectric layer. The thickness of the first layer with infrared reflection properties is 50% to 64% of that of the second layer having infrared reflection properties.
