Reflectix BP48010 Double Pack Insulation, 48 in. x 10 ft

Here in Central Arizona the summer of 2020 was the longest, dryest, hottest summer in Arizona history. That means the summer started in mid May, had more consequtive days of 110°+ temps (even at 3am it never dropped below 92°) and even though we can usually get a reprieve each summer with the monsoon rains, we got less than 1/2" of rainfall TOTAL the entire year. Usually by Halloween I need to put on a sweatshirt to go outside at night, but last year I was wearing tank tops and shorts until mid November. To say it was miserable here is a bigger understatement than saying 2020 had a few unexpected hiccups. It's now 2021, mid May, over 100° outside already by noon every day, and we've had less rain so far this year than we did by this time last year. So in order to avoid $350/mo electric bills this year, I re-sealed all my windows and doors, added UV film + Reflectix insulation to every window. I measured each window frame and cut a piece of Reflectix 2" larger in both height & width to completely block any trace of sunlight from coming through. The extra length on each side has a dual purpose. It provides enough material on all sides to not only cover the window panes, but overflows to the sides of the window frame to ensure no light (heat) can get through, and also holds the entire piece firmly in place without the need for any adhesive or other tools/hardware to keep 100% of the sun's rays out. I've had every window in the front half of my house covered with Reflectix for just over a month now, and i just compared my 2020 April & May electric bills to this year's April bill and usage so far up till today (May 27), and both of this year's bills are at least 60% lower than last year's. SIXTY percent! And that's after our electric company raised our rates 12-13% last fall. If the rates had stayed the same, the window film plus Relectix would have lowered my total cost of electricity this summer by up to 73%!!! If this stuff can reduced the cost of electricity throughout an entire Arizona summer by nearly 75% every month, you'd have a heck of a time finding a climate and situation that would test it's effectiveness as well. I'm a customer for life after the results I got this year. I bought 2 rolls (48" x 10' each) and it was enough to cover all 7 double windows in my house. It works so well at blocking UV rays and preventing things inside from getting sun bleached and dry rotted that I bought a third roll to use a window shades in both our cars so it's not 140° in them with seat belt buckles that will burn the skin right off you if you accidentally touch it. Not only does this block up to 75% of heat, but it also blocks the UVB (rays that cause sunburns) AND UVA rays (the rays that cause signs of premature aging of skin and hair.) If you are looking for a way to keep an older mobile home cool throughout the summer, grab a couple rolls of Reflectix, cut each piece 2" bigger than the area you need covered, and see how much of a difference it makes. The cost of 2 rolls has already paid for itself in the saving i got on my first month's electric bill. It's a no brainer. 2 rolls will save me over $1000 this year alone. What else is there to know?

Bought this to put inside our Dutch Star RV's windshield to protect the dash when not in use. Found out it was great to use when we're camping in an area that is facing the sun. Keeps the interior much cooler, less strain on your air conditioners. Read online (a DIY person) that you could tape it on the outside of windshield to get a more accurate fitting. Then use the windshield wipers to hold it in place, use a marker, cut it with scissors, take it inside and fit it into place. Online also suggested that you could use small, plastic Command hooks to hold in place. We didn't find the need to do that, it stayed in place just fine. Enough left over to use on entry door window for times when sun is coming in. Just roll it up when you're not using it. Very happy with product. Also a very good price ($20) in comparison to some ready-made windshield protectors that we looked at, costing between $100-$300. Highly recommend.

Love Reflextics, don't buy the copy.

I purchased this to install in my rv's windows to keep the sun out to help with the heat. I'm using this product in over 100 degree weather for months. This has helped greatly with the heat and does not let the sun in except where I didn't cut it exact. So happy with this product. I ended up using two rolls to cover all my windows in my 32 ft rv with two extra large windows. Still have some of the second roll left. It was very easy to cut and shape to the windows and easy to remove and install. I especially like that it is stiff enough that i don't need to used adhesive to keep it in the windows.

Installation should go great after I get my trailer back. I have only don't my slide and it is working pretty well. It is very warm in the summer. I cant wait til I finish installation.

This is a great product that will potentially save you money (for that you will have to regulate your AC usage) and definitively provide you comfort. We have a room that gets morning sun and then sun all day long until it sets. It is therefore the hottest room in the house. After paying out an extraordinarily large electric bill last year I thought it might be wise to buy two Honeywell MN10CESWW 10000 BTU Portable Conditioners. They work well but at the hottest part of the day the unit in that room has a hard time competing with the sun. This year I decided to do something about it and purchased this product. The difference is at least 5 degrees...at least 5 degrees and sometimes more. If you can imagine a room that is actually "cold" you will know that these reflecting materials work. I was so pleased I bought another roll. Also, I only cut one roll to size, the other three are simply pushed up against the window and sill. Perfect behind the curtains and at night I roll a portion back to open the windows. Drawbacks are a darker room but hey, I'll take some shade to heat any day. In the winter I will roll them up and store them.

I purchased this product to make a custom windshield shade for my car. The difficulty was making a paper pattern and I was wishing bad things on the COVID pandemic for keeping my yoga studio closed, as I contorted around steering wheel, center console, etc. Household scissors easily and cleanly cut the product. Used 1" twill tape to finish the raw edges, as I think they would eventually wear without support, being shoved in & out of the windshield interior moulding. With practice, I was able to fairly quickly install when needed, then fold in half and roll up for storage. I can make 2 custom windshield sun shades for less than the cost of purchasing a ready made shield. This product keeps the car much cooler than any other custom or non custom shade I've used in the past. When it's 102 degrees in the shade during a central Texas summer, this product is just what I needed.

This stuff is awesome! It cooled our travel trailer down significantly! We did all the windows and it was a night and day difference. We highly recommend this product.
