Hey guys i appreciate all you imput and theorys :) I have decided to go for panda film as it is easier to clean and does not have that much less reflectiveness over the other materials and does not reflect heat as much as mylar or any silverish material. think about this. go and look at any lampshade look on the inside of the shade what colour do you find? White, because it does not reflect andy heat making it safer. any way and colour surface has the ability to be reflective, look at still water in a lake with no waves u can see ur reflection as clear as day! :)

i have a vacuum flask the inside is mirrored to reflect heat from the liquid back against itself, the outside is mirrored to reflect the cold. this flask only has an air span between the outside wall and inside.
so you better email the company it is called thermos, and explain your findings, that white is a better heat reflector for the inside of all their flasks, you could be worth millions.
shine a very bright torch on a white wall, and stare at the reflection, will it blind you?
shine a very bright torch on a mirror and stare at the reflection, will it blind you?.
i am puzzled.
can anyone else back up the white is better theory.
when we put a roast of meat in the oven covered in tin foil, it has nothing to do with heat except keep the moisture in the meat,
if you wrap hot food in tin foil. it will keep it hot for a long time.
if you wrap it in white tin foil, you say this will keep it warmer longer. ok contact the foil companys, you may be worth even more millions.
lets start a white foil business.
ok lets start making torches with white faces surrounding the bulbs instead of silver, and..........what about vehicle headlights, i tell you, i can see it, you are going to be worth millions, maybe even billions of dollars. the new bill gates, and i am going to paint the reflective silver part of all my grow lights white.
and the inside of all my cooking pots white with heat resistant paint.

Your all over the place man. id like to have a discussion but you keep referring to light when Im talking about heat being reflected more by white than silver? blind me is not a heat term..

And tin foil has a non reflective side that goes over your chicken in the oven. The reason is you dont want to burn your outside before you meat is fully cooked. And they do make white oven covers. their called oven bags.

and once again silver is darker than white, therefore less heat. try wearing a silver shirt and mow your lawn on hot day.

If you hold up an emergency blanket/mylar to the light its pretty translucent. If your lining something like a rubbermaid grow box or pc case, the light inside will be visible from the outside. Just a heads up.

Foil tape is my vote

Over the past 18 months or so I have moved my flowering op 3 times. The first room I built was with rigid insulation with a reflective side (yeah, complete noob). Next I set up a spare room in the house using mylar (sliver, not white). I also had enough diamond foil insulation to cover about half the walls I needed to. My latest room (back in the basement, using LST) uses B&W poly. You can see this room in the Grow Room Design forum.

The room that has all white seems the brightest to me. Heat is not an issue; room is located in basement and the 170 CFM inline seems to handle it so far. Summer's not here yet though, I may need to do something later.

I plan to build a second room similar to the latest one in the basement. I'll be sticking with white, but considering white wallboard like you'd use in a bathroom instead of poly.

yes exactly if i wear a chrome silver top i would roast to fucking death on a hot day, hence they cover you in it when you are suffering hypothermia, reason, it will not let any heat out of my body. white it reflects light and releases heat from my body, if my grow room is silver it will not let the heat out it would have to be removed by fans and it will seriously reflect light back too.
as in the experiment with mirrors in my earlier post.

the lamp shade is white to let the fucking light through it, are you fucking crazy, if it was silver it would reflect the light back to the lamp and the room would be fucking dark, stop talking fucking nonsense the lot of you, silver chrome is a better heat reflector, and a better light reflector full stop. lets take the fucking argument to the manufacturers, i think you lot are talking about metal. i am talking about a mirrored surface.

any more crap talk and i will start emailing companys and asking embarassing questions which i will post in black and white against your names on this forum.
you are giving people the wrong information. white is reflective and cheap. silver is a better reflector but expensive, you can also change the spectrum in the reflected surface of the silver foil to enhance flowering, does white do that? how much is a lick of white paint, yes, peanuts.
if you want a perfect grow room use this for heat and light reflection :
this is what i use and i only grow to get rich, i dont smoke it. this shop is 8 miles from my home.
£2.10 gbp ( $3.41 usd ) per metre square does a brilliant job in all my rooms.

Damn its just people's opinions man. I sell both. I personally prefer panda because its cheap and effective and easy to work with because it comes in 10' wide lengths when mylar is 4' wide. Thats my opinion, no crap talk

mylar cons/ cost more, see though, thin and hard to handle

so you buy what you buy for the length and width, DUH, the heat resistant and reflective plastic sheeting i use comes in lengths of 6.56 feet by 328 feet i just seal the joints with 50mm wide reflective tape.

you can buy an automatic powder fire extinguisher if your that paranoid they are cheap. go for the 6kg one.
if you want to give out information about fire prevention, do it on another thread. http://www.fireprotectiononline.co.uk/automatic-fire-extinguishers/
this is a reflective material thread, the fucking stuff your smoking is blocking the electronic pulses in your brain, your getting your wires crossed, lets talk about heat and light reflection here.

Poeple do wanna discuss pro and cons here if you keep it factual and not personal. DUH, and blaming weed is not factual evidence of the pros of mylar.
Where did you buy that weird length, a farm supply store? thats not a standard size.

cammmmmon, lets get more arguments going, who else says white is better to reflect heat and light.
we need to sort this for once and for all so i can start contacting companys that make heat and lighting equipment.

i used that stuff called reflectix on the inside of my room on the walls and ceiling. about 2 weeks later i covered the reflectix on the walls with panda film. i noticed the room was cooler after i installed the panda film. as far as reflectivity, the reflectix seemed brighter but i like the white from the panda film better. its also easier on the eyes when in the room. the panda film cleans easily and is very durable.

i would have used flat white paint if it was practical, but not for this room.

i have never used mylar.

Personally for me I use flat white paint in my room,i also used some of the orange peel speckling on the walls before painting to reflect light to different areas so it is not a flat surface.I do not need heat in my room,its my enemy,so while the white paint may not have the reflectivity of other materials it seems to keep my room cooler.This is just my own 2 cents your mileage may vary...
