I Tested And Reviewed 7 Best R Value Insulation For Walls (2023)
Choosing the right insulation R-value for your home's walls is crucial for providing comfort, energy efficiency, and savings on utility bills. When shopping for insulating materials, determining the optimal R-value is key before making a purchase. But what factors should you consider when selecting R-value insulation for walls?
Firstly, examine your climate zone and average outdoor temperatures. Areas with extreme winters require insulation with higher R-values between R-13 to R-23 to prevent heat loss and drafts. Meanwhile, moderate zones only need R-11 to R-13 insulation. Consulting a climate zone map helps match your location to the ideal R-value range.
Next, consider your wall assembly type – wood stud, concrete, double stud, etc. The wall's materials and depth impact the R-value needed. For example, a 2×4 wood stud wall requires higher R-values than a 2×6 wall which has more depth. Understanding your wall structure identifies the correct insulation thickness.
Finally, weigh the insulation type – batt, rigid foam, blown-in, among other options. Each has different R-value ratings at certain thicknesses. Compare materials to see which provides the necessary thermal resistance at the right depth for your wall cavities. Also factor if it's for new construction versus retrofitting existing walls.
Installing wall insulation with the proper R-value boosts energy efficiency, reduces utility expenses, and enhances home comfort. Take time to carefully evaluate your climate needs, wall assembly, and insulation types to choose the ideal R-value range for your situation before purchasing. With the right insulation, you can gain savings while creating a warmer indoor space.

1. Smartshield Reflective Insulation Roll: Radiant Barrier For Maximum Efficiency
I recently purchased the SmartShield insulation panels to fit the windows in my camper, and I must say, it has made a significant difference in temperature control. I used double-sided 3M Velcro to attach the panels, and they worked wonderfully. The best part is that they can be easily popped off if you want to pack them away or enjoy the surrounding views. I noticed a drop of 20 degrees in the temperature inside my camper during the summer, making it a much more comfortable experience. I highly recommend this product to all my fellow camper and RV enthusiasts.
I also used these panels to insulate the windows in my RV. The 20mm thickness of the SmartShield insulation worked great for this purpose. I cut the panels to fit the windows, and the small panels on six windows made a huge difference in maintaining the inside temperature when the heater was running and it was below freezing outside. The 20mm thickness provided the necessary strength and rigidity when cut into 32×18 panels. I am quite pleased with how well it insulates. However, for those who are only looking for RV window coverings, the 25' roll may be too much material. Nevertheless, I am sure I will find other uses for it.
In addition to using it for my camper and RV, I also bought this insulation to cover the louvers on my whole house fan. I had previously used pink fiberglass insulation in the attic, but there was still air transfer. The SmartShield insulation proved to be a clever solution. I opted for the white side to blend in better with my ceiling, and it worked perfectly. The construction of the insulation allowed for easy joining of pieces without creating visible seams. I only needed a three-foot square for the whole house fan, and it was a breeze to cut with an electric bread knife.
I did encounter some issues with the adhesive aspect of the insulation. I used an industrial strength adhesive Velcro to hold it up, but it didn't stick. I also tried taping it with packing tape, which didn't stick either. This was true for both the reflective side and the white side of the insulation. However, regular gray duct tape, actual metal duct tape, strapping tape, and industrial double-sided tape didn't work either. Surprisingly, purple duct tape did stick, and the Velcro was able to adhere to it. It's puzzling why purple stuck while gray didn't, especially since both were the same brand.
