Sunshade Color
Hello, all. I've had one of those inexpensive (foil on cardboard)
windshield sunshades for quite some time and I've never understood why one side is silver while the other side is blue. I've always placed the silver side facing the sun figuring it was the most reflective. Does the blue side serve a practical purpose? Thanks for your time and comment. Sincerely, -- J. B. Wood e-mail: |

Probably for show. I've seen the other side available in
several colors. Blue is also less heat-absorbant than, say, red or brown. |

It may just be what the maker had on hand and needed to use up. A lot of those shades are multicolored, and/or have text or logos on them. In the dark days before cell phones, some had the words "Need Help. Call Police" on them |

A lot of people who have RV vehicles (campers and motorhomes and trailers) use Reflectix for insulaion on windows. |

That would be nice, but people steal anything that isn't nailed down :-( I'd just like to make the steering wheel a little cooler when I get into the car. -- Cheers, Bev The early bird gets the worm, the second mouse gets the cheese. |

You are probably correct but not allowing the solar rays to enter the interior might have a big impact on the temperature. It might make a good science project for school kids.

It might make a good science project for school kids. "Crime rates and the effects of not nailing things down." I don't know about nowadays, but in Russia people would steal the windshield wipers off of cars. |
