Abstract
A material includes a transparent substrate coated with a stack of thin layers including a silver-based functional metal layer and two dielectric coatings, wherein a lower dielectric coating located below a silver-based functional layer includes a high-index layer based on metal oxide, an antidiffusion layer based on silicon and/or on aluminum, at least one oxide-based layer located above the antidiffusion layer and exhibiting a different composition from the antidiffusion layer, such as a smoothing layer and/or a wetting layer.
