Blue Windows on Catering Trucks

Factual Questions
1

Hi All,

I’m trying to figure out why blue-tinted windows are a common feature on catering/lunch trucks. Often, the overhead sunlights and side service windows are blue. When not blue, the windows may be untinted, but almost never another color.

A few examples from different manufacturers:

I’ve emailed a few of them with the question, but have not received any replies. :slight_smile:

What’s so special about combining blue windows with food service?

Those aren’t catering trucks.

THIS is a catering truck!

Interesting question. I’ve noticed the blue tint, but never gave it any thought. Maybe blue has a psychological effect, making the caterers feel cooler than they would if they had amber tinting?

This is only a guess, but maybe it’s to help with the heat from the sun beating in, yet still allow customers to see inside, unlike with dark-tinted windows.

They might be made out of PVC instead of acrylic or Lexan. (The generic term for the plastic of Lexan is evading me at the…ahhh polycarbonate!)

“Clear” PVC has a blueish tint, quite noticeable when thicker than 1/8" or so.
Smartassed answer: The cockroaches prefer blue light.

Is that what they call “Feeding at the trough”?

Could have something to do with it. I would imagine it gets pretty hot in there.

Iteresting. I don’t think I’ve ever seen one with blue windows here.

I finally remembered to ask the guy that runs the roach coach that stops at work.
He had no idea (and his truck has blue windows)
