2-Pack Silver Highly Reflective Mylar Film Sheets by NAVAdeal

bryceguy72: So these are very light, thin sheets but they're quite durable. I fully expected them to tear while being a bit rough on them, but they held up. They are surprisingly tough considering how thin they are. Maybe that's because I wrongly expected them to be as fragile as thin aluminum foil.

Speaking of which, these sheets are NOT like aluminum foil which is 100% opaque. These sheets reflect most light but they are transparent, I would estimate around 95% reflective and 5% transparent. You can see right through them, but you have to be looking at something bright, like the sky or day-lit scenery.

Second Options: Good either for outdoor emergency kit or hydroponic light reflectivity.

Solid value.

T.B: Not the highest quality but seems to be preforming ok. This type of product thinner product is never easy to work with unless you use proper technique when applying. Couple decades ago before everything was made oversees I fell like the quality and thickness was greater which made it easier to work with. But this is low cost and ok if you take some effort to apply it. However, I would not use in a large grow or anywhere you expect it to last to long. If you have a small window or closet garden to increase sun/light on a handful of plants maybe ok but I would not expect you would be able to line the ground outdoors as pictured wind and debris would destroy it immediately.

I adhered it to some rigid panels for small area that does not get a full day of sun and it is holding up at least for 5 days

Laotis Buckley: I used 2 of the films to create a grow box for my seedlings (lined the inside of a cardboard box with it using glue sticks and will cut a rectangle in the top of the box for my 36W LED (360 HPS equivalent light to shine through). I also glued wood strips to the outside of the box at the bottom to make it more sturdy. Also, I used 2 of the films to attach over the top of my 200W LED (2,000 HPS equivalent) light in my mylar tent, and let it drape down over the plants. I'm growing herb in a 32X32 tent and wanted to condense the light. This way the area is about 28X28 instead of 32X32

Russell J. DionneRussell J. Dionne: It seems very effective at reflecting the light back into the shelving unit, where before the whole room was getting flooded with light the thin sheet blocked the light to the point seen in the photo i uploaded.

Rosey: I got these to help reflect the heat from sunlight pouring in through some windows. It was easy to handle (be careful unfolding it because if you unfold it too forcefully it will tear,) lightweight and it does indeed help reflect some of the searing heat coming in the window. It still allows me to see out, although the view is a little unworldly, silvery and dim, rather like a special effect for a sci-fi movie. My windows are not subject to birds crashing into them; you'll want to make sure birds don't think they are seeing a throughway. Something to be mindful of since we share the planet with birds. Because these packages are so small and lightweight, they'd be nice to have in the car or in a backpack in case you must be out in harsh elements.

I needed two layers to achieve exceptable light blocking
