Heated Glazing for Vehicles

Michael R Greenall

The presentation addresses the present status and future developments of heated vehicle glazing. It will be particularly relevant to those specifying glazing performance and will also be of interest to glazing suppliers.

It will review the various heating technologies available; namely printing, wiring and metallic coating and discuss how these can be used to design glazing which has either full surface or local heating. Options for the principle vehicle glazings will be addressed. Some of the manufacturing methods will be described.

Typical performance specifications and the importance of voltage levels will be discussed. It will introduce the challenge of integrating heating systems with other vehicle systems such as rain sensors and telepass.
