What Customers Are Saying

Customers overwhelmingly praise this blown-in fiberglass insulation for exceptional ease of installation and superior performance. Most complete large attic projects in under four hours with a two-person setup. Reviewers consistently report the product is virtually dust-free compared to alternatives, with many noting "no itching" and immediate improvements in temperature control—homes "stay cooler upstairs" and "feel warmer immediately." The insulation doesn't settle over time and includes a lifetime warranty. While most find it vastly superior to cellulose, a few report occasional machine inconsistencies, though these rarely reflect on the product itself. Overall, customers strongly recommend it for DIY attic projects.

Easy Installation

Would Recommend

Much easier to deal with than cellulose. Low dust and not itchy!

Saving money from day, one!

Bought about 20 bags to do my attic. It was a 1970 ranch where the insulation had settled down to about 2 inches. I use the equipment provided by Lowe’s and it worked very well. My furnace is running about 1/3 of the time that it did before insulated! The house is also quieter with the added insulation. I blew in 16 inches.

Insulation

Would Recommend

This is a great product. The machine to blow the insulation works well with the product. The product breaks down quickly and doesn’t jam in the blower.
