Does this product work for reflecting direct sunlight? I want to use it on my windows for energy efficiency and to keep light out while sleeping?

I used the product on a garage door and it does help. It might work better on glass but won't look very good.

I bought this item to insulate my garage door which works very well. I'm not sure how good it reflect sunlight since its in the inside.

i don't know for sure, but i would think it would.. The material looks like that stuff you put in your car window to keep the dashboard from cracking and to make the car cooler. this stuff has worked out great for me since i put it in.

Plain aluminum (kitchen) foil works well for this purpose. This product should work a little bit better as it will (slightly) reduce conductive heat loss as well.

I believe this product would work very well reflecting direct sunlight. Having a 1/4 inch bubble wrap middle, covered on both side with a shiny aluminum sheet, it is completely opaque, and should not allow any light to transmit through it. It should work very well for the purpose you intend to use it for.

I do not think it reflects during daylight - only if a light is directed on it.

this might work, if exposed to enough light. something reflective might be a better choice. maybe a trial test would be in order to find out for sure.

I feel it dulls the sun. Like I said, light is still filtered through. It isn't harsh light, but it doesn't block out the sun.I may sound silly saying this, but take a dryer sheet or two and hold it up to the sunlight that you're hoping it dulls. I will most likely have that effect if you buy this. I have 2 of these up around my bed since I am sharing a room. I can say that I am not woken up by hard sunlight like I was before I got these.

Yes. It will reflect the light while absorbing some of the direct harsh sunlight.

Did you end up buying this item to use to black out windows? If so, how did it work out?

It is "Solar" powered, and the sun is the equivalent of a high wattage light bulb. If you used a florescent, LED or any bulb less than 100 WATT, it will not work very well. It will function great near a high wattage bulb or in the sun.

It is a very thin piece of cloth so I do not think it would help much with sun. It is not reflective and might actually absorb sun.

it definitely needs sunlight! its also very bright. I actually get about 3 hrs of sunlight where i placed it. its placed above my front door, no more fumbling with keys and i don't have to use my electricity.

Not me, but if there is glass in front of it (like a storm door) it is useless at night due to the reflected glare of the infrared. I covered the infrared led's.

Hi, this will not work though windows. The reflection of the glass will reflect the heat. Same thing when using in a car. The windows must be rolled down to see past them. Hope this helps..

Yes, it works very well without direct sunlight. You will find that even on an overcast day, the indirect light is picked up by the solar panel and it activates the fan.

No it would not block sunlight, though it would partially block it. It's made of a fairly thin plastic.

There is a company window film and more that sells (windowfilmandmore.com) that sell sheets of one way mirrors (the stuff that I guess is in the window feeder that costs a whole lot more), and other glass covers that may work. They sent me free small samples (three total) but I haven't used anything yet because it hasn't gotten warm yet :) ... but any of the three look like they will work. I'm planning on using it for the window bird feeder also. (which ever one I end up picking)

I have had this product on my window for almost 4 months in direct sunlight, it stays looking the same and its beautiful. I have had more comments on my windows. But you will not be sorry buying this. Hope this helps.

No. It's very reflective. Like a sheet of glass would be. Works better in a dark room.

That's exactly what I do why mine. Works well but there are some issues.The IR lights can cause an intolerable reflection off the glass. You may need to cover them with black tape.Also sun glare of the window glass can be an issue, best to point it away from the direction of the sunlight.
