What Customers Are Saying

The reflective insulation product appears to be a versatile and effective solution for home and RV insulation. Customers report it is easy to work with, install, and cut to size, making it suitable for various applications. The reflective properties help regulate temperatures, keeping spaces cooler in hot weather and warmer in cold weather. The product is particularly well-suited for insulating areas with large windows or exposed to direct sunlight, as the reflective layer blocks heat transfer. Customers also mention using it to insulate water pipes, crawl spaces, and attics, often in combination with other insulation types. Overall, the consensus is that this is a high-quality, effective product that can provide significant energy savings and temperature regulation benefits.

Insulation from solar heat

Would Recommend

My parent’s use this product in their RV and also in their home. My front door gets extremely hot in the summer. I covered the glass and it is a lot cooler. So I did the storm door on the side of the house too. Makes a huge difference. Thinking about making covers for my vehicle windows too. Would purchase again.
