- Heavy Duty 5mm Reflective Insulation Roll - Premium Foam Core Radiant Barrier for Energy Conservation -Commercial Grade Soundproofing Thermal Shield for Indoor and Outdoor Use (48" X 25')

The Context: Insulating an RV is tough because you’re battling extreme temperatures on both ends of the spectrum. I used the SEALTECH 5mm Reflective Insulation Roll to beef up our camper’s thermal efficiency, and it has honestly been a game-changer for seasonal comfort. The Performance: Summer Performance: In the summer, this stuff is incredible at blocking out the sun. Lining windows and key interior spots with it significantly reduces radiant heat gain, meaning the AC doesn't have to work nearly as hard to keep the rig cool. Winter Performance: When it gets cold, it does the opposite. By adding that extra layer of thermal reflection, it helps trap the interior heat and prevents the rig from losing warmth through the thin walls and windows. It makes a noticeable difference in how often the heater needs to cycle. Ease of Use: It’s super easy to work with. It cuts cleanly with standard scissors or a utility knife, and it’s flexible enough to shape into tight corners or window frames. It’s lightweight but feels durable enough to last through a lot of road travel. Pros: Versatile: Effective for both extreme heat and cold. DIY-Friendly: Extremely easy to cut, shape, and install. High Performance: Significantly reduces the load on RV heating and cooling systems. Cons: None: It performs exactly as advertised and is a must-have for any serious RVer. The Verdict: If you’re tired of your RV feeling like an oven in the summer or a freezer in the winter, get this insulation roll. It’s an inexpensive, high-impact upgrade that makes a world of difference in your day-to-day comfort.

This was an awesome product and great for keeping the 100F plus heat out of the house! We used it in a bay window and it cooled down the room tremendously by keeping the heat outside! I’d definitely recommend it for that easy DIY project of insulating your house or apartment with very little effort. All I needed was a good pair of scissors and a tape measure. It was easy to measure, cut and install! It’s worth the price in saving on utilities for your home. I’d recommend getting some because it’s easy to install and take down if needed!

Used to insulate chicken coops during cooler weather here in South Carolina and it worked great! Much thicker than other brands, is not flimsy, worth the extra bit of money for the thickness. Definitely recommend.

This has worked great this entire summer. We shall see what it looks like next summer. But it has been extremely helpful keeping the heat out of my travel trailer ✨✨✨✨

I used this to insulate my garage and it is awesome! It is easy to cut and made a big difference in our garage- I also used “great stuff” to seal all the holes and replaced the frame outside. Came just in time for the snow storm !! Easy to cut and great quality - you have foil on both sides with foam in the middle ! And it looks great ! Got the aluminum foil. You can also get double sided tape to tape it to the garage door so you have some space between the garage door and insulation . Would highly recommend it. I will be using it in our outer shed a bit later !

Very easy to use. Able to be cut with scissors or a box cutter. Adheres great with some spray adhesive (I used 3M heavy duty). Very easy to fit into tight spaces and the versatility makes it useful on a various things. I used this to insulate garage doors. I still need to use a thermometer to measure the exact heat reduction inside, but so far it definitely is noticable in reducing the temperature inside the garage.i would buy again.

This stuff is amazing!!!!10/10 was super easy to wrap my trailer with cuts easy but very strong.keeps out all wind and most cold better then anything else I’ve tried..(I’ve tried double thick plastic on inside and out…)and this is 10x better and easier.and it goes a long way I measured and everything and it went close to double what I had expected so you also get more then your think.if you live where there’s winter this stuff is a no brainer do yourself a favor get it and thank me later

I have a garage fridge that shuts off sometimes in the winter. I bought this insulation to cover the fridge and protect it from the cold. I’m very happy with the quality! I read reviews with other similar insulation and people complained about them being delivered with fold creases, being too thin, and being shorted with the measurements. This was delivered in a roll so there were no creases and it was measured perfectly. It was also a nice thickness and easy to work with. My fridge is not super large and there wouldn’t have been quite enough to put any on the front since I did cover the back (minus the small circulation area at the bottom). I didn’t want it to be on the front of the fridge anyway though. This isn’t a perfect solution for the garage fridge shutting off in the cold because I still needed to install a little thermostat heater thing, but this helped a lot. It’s also less bulky and instrusive than some of the premade fridge covers.
