I use a product called "Heatshield" from a company in Sunnyvale CA. It
appears to be some kind of 1/4" foam with silver reflective coating on one
side and white on the inside. It is edged in black cloth and is rigid-yet
flexible. It fits in the windshield without any need for holders - and when
you are not using it, you roll it up like a large map and there is a velcro
strip to hold it together.

Unfortunately there is no phone number on the product.
