Abstract
A coated sheet for use in a laminated assembly and having a high level of luminous transmission and a low energy transmission includes a transparent substrate carrying a coating including two metal layers formed of silver or silver alloy and three layers of a transparent dielectric non-absorbent material, in the sequence, from the substrate: non-absorbent 1/metal 1/non-absorbent 2/metal 2/non-absorbent 3, wherein the two metal layers have a total geometrical thickness which ranges from 16.5 to 22 nm, wherein the non-absorbent 1 layer has an optical thickness which ranges from 50 to 56 nm, wherein the three layers of a transparent dielectric non-absorbent have a total optical thickness which ranges from 220 to 260 nm, and wherein the coated sheet has a thickness ratio of non-absorbent 2:nonabsorbent 1 which ranges from 2.1:1 to 2.8:1.
