SOLAR CONTROL GLAZING

摘要

The invention relates to heat treatable solar control glazing showing low- emissivity properties, and possibly also anti-solar properties and methods to manufacture such glazing. They comprise a transparent substrate coated with a stack of thin layers comprising n functional layer(s) reflecting infrared radiation and n+1 dielectric layers, with n≥1, each functional layer being surrounded by dielectric layers. At least one dielectric layer above a functional layer comprises a layer consisting essentially of silicon oxide, preferably deposited by PECVD,and the stack comprises a barrier layer based on zinc oxide above and in direct contact with any functional layer which has a silicon oxide layer in the dielectric layer directly above it.
