Blinds For New Fish Room?

[ReefWaters]

I'm setting up a 230 gallon in-wall display and the fish room is in what is technically a "sun room." There are three large windows in the small room. So I want to block the light, in and out, of the room as close to 100% as I can.

I've found "blackout" blinds (single and double cell) on all the big blind websites, but I was wondering if anyone has found anything else that works as well or better? Or has anyone used these blackout blinds and liked them? I'm more concerned with light leaking out of the room at night than with light coming in during the day.

Any help or opinions would be greatly appreciated.

I own a blind business and the double cell blackout or even a shutters would work great,

Is there any major difference in the double cell versus the single cell....other than having an extra cell? :lol: But really, do they block more light or anything like that?

I'm relatively sure it is talking about the thickness. I have some of these in my room at home and they work great.
