black perforated on window?

[JoySigns]

A new grocery store wants black perf put on some high windows (this is new construction) that are south facing and are letting in too much hot sun that is shining onto their deli meat coolers. I know solid black is not a good idea on windows, will the black perf be OK? I've never worked with perf films before, is there one available that come in black or do I have to get black printed on the film? Any suggestions would be appreciated. Thanks.

Sounds like a job for window tint...

I'm not aware of perf coming in colors. I'd agree with jfiscus though. Unless they are wanting something printed on it - tint sounds like the best solution. You could always just print the perf with solid black though and go that route.

We've used perf that is black on the adhesive side. Is it an option to install the perf on the window interior (assuming they want black facing the exterior)? That'd leave unprinted white facing the interior of the store.

It's not really accessible from inside, otherwise that would be a great solution.

I think all perf come with white front and black back. But for this job i would tint the windows.

It may depend on what you're referring to as "perforated".

Perforated black vinyl is commonly used on channel letter faces so that they appear black during the day but illuminate a different color at night. It's more commonly referred to as "day/night" vinyl and is typically black or white with both being white on the back. Of course you can digitally print any color on the front of the white.

All black vinyl perf or not is only going to do one thing...create more heat on the windows and possible break them.

This is a job for tint. You will have proper options to combat the sun's rays and the heat. Talk to a tinter.

3M makes a silver tint that is designed to be installed on the exterior of windows.
It would be your best bet if you can't access the inner sides of the windows.
A silver reflective film will reject the most solar energy with much less of an increase in the heat load on the window vs something dark placed on the outside.
A dark film is going to heat those windows same as it would in a roof mounted solar water heater.
