Rflective walls, what to use.

[grow nerd]

havent had issues with that...

Haven't had issues with what? If you meant you have no issues with keeping the room cool, that's not what I was getting at. I'm asking how you evacuate the heat. It might be great that the room itself might not radiate a ton of heat, but how you exhaust and take care of that heat output is a major part of anti-IR detection. It's not necessarily just several giant hot spots (sign of HID lamps) in the middle of a room that's being watched for, as that's rarely the case, but instead paths of heat (including duct runs), unusual heated areas, etc.

have my exhaust set up now with AC on the way. the walls arent warm to the touch or anything like that...the heat is vented into a crawlspace under the house where its mixed with cold outside air...

This confirms that you are clearly confused about IR detection and what "they" look for. A warm crawlspace (or any space, at a time when it's normally cold) will stick out like a sore thumb, including warm air seeping out from the house's crawlspace vents. Ever see that video about a guy in Detroit (I think) being spotted out after the IR cameras spotted an unusually hot chimney?

 

[clampie]

absolutely, g.n....
honestly, he's right, if paintings not your thing, you can get away with a couple of coats of Kilz 2 or Kilz Premium. Whatever you do, don't use Kilz "original." It's oil-based...

yea i saw that episode in detroit..i thoght i remember his whole house was glowing red. the vent is at least 12 feet away from the small holes in the crawlspace...so the hot air has alot of space to cover before it goes outside. the entire crawlspace is huge too..but yeah maybe hot air seeps out through the small gaps.

either way, i live in oaksterdam and they do not have IR choppers out here thank god.

So why bother with all this "anti-IR" stuff for the sake of "anti-IR"? Just curious...

dry wall first sealed with a good quality sealer then a coat or two of bathroom paint with built in mildacide and fungicide. SO far I'm 3 years on this room and the walls have been bleached 20+ times and are still in great shape. The best part is the walls aren't covered in flammable plastic.

This sounds like the best way for me. Im scared of fires

 

[Yes4Prop215]

when i bought it i just did so because i have seen other people on IC using it and like i said...TO KILL THE FLAPPING!! haha....the IR blocker was just a plus to using it...if it doesnt work 100% to defeat the evil black helicopters oh well...im within my limits not growing for profit.

 

[Guest 18340]

I use Reflectix, the stuff Yes4Prop215 is using. It's reflective AND insulates. My room is completely sealed and I use a mini split so no air, warm or otherwise, ever escapes...

Great excuse/afterthought. Or lack of proper research.

Keep in mind Mylar is easily flammable.

GN, why do you care so much the reason Yes4Prop215 uses Reflectix? So he didn't purchase it for it's obvious benefits, but whats it to you?

 

[nightcrawler]

I've had experience with both mylar and panda, and have since settled on flat white paint on everything. get a can of spray paint and hit anything that can't be brushed. Make sure you use a primer first, and then two coats of flat white topcoat (slight scuff between coats). It is a bit more work, but you can wash it, it diffuses light better than mylar, and doesn't reflect heat the same way. Also, you'll never have problems with moisture trapped between the plastic and a wall, causing possible problems.

Panda, however, is great for making doors for light-tight-edness/etc. I put a zipper in the middle, fasten it around the doorway inside (or wherever), and it works great for light, and to some degree, air..

hope the input helps, and good luck!

Looks like everyone is ging with flat white paint. Ill be painting tomorrow

I don't, I'm getting to the logic/reasoning behind (improper?) selection.

First, he said it was because he wanted to block IR, to not be detectable to FLIR cameras and whatnot. When I shot that down, he then switched it up and said it was to reduce flapping. Sounds to me like backtracking and color-up to make one's self feel better about a costly purchase. Only confuses matters and incorrectly informs the other/future readers.

I'm pointing out that if the intention is to block IR detection (as originally stated), then he's going about it the wrong way due to being misinformed/misunderstanding the concept because anti-IR detection is more than just "filming up".

I like a little debate; it oftentimes reveals a lot of hidden details and intentions. Am I so wrong in doing so? Why do I always have to be the bad guy? Or are you afraid of a little education?

He answered your question and then you come back with this snotty remark...

Great excuse/afterthought. Or lack of proper research.

THATS why you come off as the bad guy.

 

[grow nerd]

No, it's called the truth. If all you want is to feel good about yourself and your (incorrect) decisions, then keep yourself in the dark, do what you want, and pat yourself on the back. Sometimes, making the wrong choices can be painful (in more ways than one, including emotionally, sometimes financially), but that's a part of learning and that causes you to not repeat the same mistakes over and over.

There's doing the right thing for the right reasons for a good result, and doing the wrong thing for the wrong reason and getting variable results. If you choose to randomly take shots in the dark and be surprised by the results, be my guest. I choose to be well-informed and have reliable, predictable results.

Reflectix is awesome material. I wouldn't even consider it "costly". I think you are just looking for an arguement, for whatever reason...

A decent gallon of paint is over 20 bucks. We are talking about nickles and dimes...

 

[clampie]

well, Nightcrawler, for no reason other than to share , as I've seen people (builders/plumbers/electricians) do with other threads, I started a new thread on "painting the growroom"
I know at least one other pro painter on icmag that is going to chime in as well.. Feel free to say hey over there, or share your process.

Best of luck!

 

[dubwise]

I use the IR blocking stuff as well, and it's great to work with. It was not as cheap as paint, but it went up in no time. The room is sealed w/ AC, all exhaust is split to the dryer and two bathroom exhausts.

I'm sure it's great, if you're using and implementing it properly for the right reasons. But in this case, it was used for the wrong reason and improperly implemented for that cause.

I think you're just looking for a reason to pat yourself on the back.

Less than $10, or $200; and performance. Yeah, nickles and dimes.

And these same people talk about not being able to afford certain critical key components of a room. I wonder why.

 

[Guest 18340]

Seems like you're taking his choice of reasoning too personal for some reason. Again, whats it to you that someone may have chosen a product for the wrong reasons? If you want to educate people then theirs better ways to do it than baiting someone.
Anyway, back to the topic at hand, what reflective material should the OP use...

 

[grow nerd]

I'm not baiting anyone for anything, or trying to "put someone down". I'm simply getting to the bottom of the reasoning/logic behind decisions, and explaining these choices and the consequences they have. If you choose to view it your negative way, do so, but future readers of this thread will now be more fully informed of their options and the implications of those options.

Would you prefer "Good job buddy!!! Great choice!!! I would have done the same!!!" for everything, regardless of good or bad, right or wrong, agree or disagree?

Not everything in life is fun and jolly, including making the wrong choices. This isn't Disney.com, we're not children, and as adults, I'm sure we can handle such emotions.
