winemana6 Pack Large High Silver Reflective Mylar Film, 83x 63 in, High Reflectivity, Keep Warm, 100% Environmentally Safe, Perfect for Plant Growth, First Aid, Marathon, Camping, Outdoor Survival

I wasn't quite ready to commit to a huge roll of mylar right off the bat so I thought I would give these a try. Very happy I did. They are perfect to reflect light back into my metal shelves and all it takes to hold them up are two bags clips so I can easily take it up and down when I need. I don't know yet how it will hold up to that kind of use long term but luckily there's six of them and at this price I can always buy more. It's hard to tell from the picture but these are somewhat translucent which is a plus for me since it allows me to see through to my plants

I had no intention of using these as a blanket. I bought them because I wanted to make a highly reflective surface around a wire shelving unit where I have hydroponic lettuce growing.I know I can just go out and guy a grow tent that has its own shiny internal lining, but I didn't want to. I wanted to use my existing wire shelf rack with a removable siding. So I purchase these because they were very large and wouldn't require me to piece many of them together sloppily. So I gook an old box from a TV I had sitting around and some spray adhesive and simply cut my box into pieces (2 pieces for front and back, 2 pieces for sides, and 1 piece for top). I taped it together around the rack and cut holes where I needed them for cables and to hold fans. Worked perfectly! Now I'm taking advantage of all the reflected light from my grow lights and have a fully removable, modifiable, and light-weight housing for my shelf. I even have a removable front-piece held in place with magnets for when I want to remove just that part. So instead of a $50+ grow tent I have a 3$ one that does the same thing. Now I'm going to go and grab myself a $47 steak because I earned it :)I know some people would have said "why not just use aluminum foil". I'll tell you why not.A) More ExpensiveB) I would have had to do it in stripsC) Harder to deal with, mylar is SIMPLED) MOST IMPORTANT: Aluminum foil is conductive to electricity, Mylar is notE) Tears easily and wrinkles, mylar stays pretty flat and even

Works as it should pretty reflective keeps heat in or out. Coating could be a little heavier but pretty good.

Needed to adjust the lighting in a greenhouse.The mylar is identically reflective on both sides and equally translucent on either side. Excellent thermal insulation. I was able to fold and refold, crinkle and re-adjust the mylar multiple times. As long as you take your time and don't rush, the material doesn’t tear. Too many refoldings along the same fold can split the reflective coating and sharp edges can scratch the surface. Overall, great product for the price.

This is less than paper thin and barely any weight to it which is perfect for my craft project. I am not using it as most folks. I am making specialty designed paper crafts so this light weight is awesome. The sheets are very large and I will have plenty of product to use. RE: window covering… This is a large size - see details as described- and can fit on garage windows or others to block sunlight. Not sure how I would get out the folded marks it has as the way it is packed but I am guessing you can use window “glue” to adhere to window and that will get rid of fold lines. Looks like it would help reduce sunlight and heat inside because of the material here. Read seller’s descriptions. I am happy with my purchase. But, read what seller wrote in detail so it works how you think it will work for you. Again, I read details and for me and the price this is perfect. Thank you

Works but very thin. Rips easily. However very reflective and sized well making them easy to design with.

Perfect for what u needed it for. Thin yes, but durable enough to work with without it tearing to pieces. Perfect for my application

Products like these should be used in all construction projects. My hime built in 1921. Used in conjunction with plastic on the windows. Has made a real difference in my bills. Can also be used on walls to help insulate.
