Camco 45167 SunShield Reflective Door Window Cover | Helps Protect Your RV from Harmful UV Rays and Regulates RV Temperature | 16" (L) x 25" (W)

This product is well made and it works great in the Summer to reflect the sun and heat away from our 5th wheel RV windows. It definitely lowers the indoor temperature and allows the AC unit to work more efficient. In the Winter it helps insulate the windows because the product has small air bubbles embedded into the design which act as an insulator. Overall a great product. Be sure to select the correct size for your needs. I prefer a size slightly larger than the window itself to allow for full coverage and some overlap if you select anything smaller than the window then you will not receive full benefits of the product. In my opinion this product should be used inside on the interior and not for outdoor use. I don't recommend cutting this to size for a window because it has finished edges that if cut could unravel or cause issue with the product. Instead I would just fold to make it fit and leave the finished edges intact.

I am using these to help keep the sun out of the trailer while stored in hopes of prevent UV damage. The material seems relatively thin and I am concerned about how long it will last. It is held in place by velcro so installation was really easy. With the feel of the material and the price, I am of the opinion that it may only last a season. The material does not feel like it will handle many cycles of removal before it tears. Overall, it does block out the light very well so it is doing its job. Just don't expect this to be an item to last long term. I am giving it five stars simply because it does work well and the quality of the product matches the price paid.

We actually used it to cover a skylight in the camper shower to keep out light and heat. Works great. We used Velcro to put it up so it’s easy to pull down when needed.

Fits our Jayco door window perfectly. Keeps the sun out and insulates as well. Very happy with results. Seems pretty durable and the tape used for connecting the Velcro to the wall seem to stick firmly. May bump up to five after more use, just one trip so far.

Used on windows indoor. Decreased my cooling bill in Florida summer heat significantly! ❤️

This past July I pulled my travel trailer from TN to southern CO. On the way out I didn't have these, and every day when I stopped it was over 100 degs in the camper. It would take 3-4 hrs to get the temp below 80 degs. I bought several of these while in CO and covered all of the windows and the skylight on the way back. They made a significant difference in the inside temp while towing and, especially, in reducing the temp once I stopped.

Bought 2 of these for my trailer door windows. Velcro was easy up, fit almost perfect. There’s a very bright spotlight for the park that shines so pretty and bright all over the broad side of my trailer at 1 in the morning. Not really enough velcro squares to completely put across the very bottom, no problem, good ole Duct Tape to the rescue! Love these, everything’s dark now. I’m

The size was a good fit but very thin. You could see the outline of the window glass when the shone on it. Ones I bought in past were truly blackout. Easy to install but it needs at least two more Velcro squares to fit snuggly.
