What Customers Are Saying

This blown-in cellulose insulation is generally effective at insulating and reaching difficult areas. Customers report good insulation performance and cost-effectiveness. However, some experienced issues with the rental equipment, such as clogging and limited availability of functioning blowers. A few also noted the dustiness of the material and presence of debris. Overall, most customers were satisfied with the product and would recommend it as a good DIY insulation option that can provide significant energy savings, despite the potential challenges with the installation process.

It was a new experience for me being a new home owner. First I ordered the insulation way ahead of time to be sure it was ready for when i needed it. The constant texting for pickup was a bit much, then when i went for for the pickup I was shorted 4 bails that i had to go back for. Now i have been told that the blower machine is not working.....WOW. I'm in the processes of trying to find another store to get the blower machine. What would happen if my money wasn't complete??

Do no order online

Would Not Recommend

No issue with the insulation, but I saw the best employees of lowes and the worst trying to get this material. When you order so much, the machine rental is free. I found out that Bardstown, KY Lowes does not have a green cellulose machine to blow this insulation. I spoke with a representative after placing the order online who told me the machine would be ready to go at pick up. 60 bags of insulation with a crew to help blow in, I spent 2 hours calling and running to get a machine.

Incompetence at its finest

The product is fine. The delivery service has been nothing but terrible. It will be much easier to pick it up yourself or go elsewhere.

Check the blower equipment.

Would Not Recommend

The insulation was good except for one bag that was contaminated with string. The string bound up the auger in the blower and it took an hour to figure out what happened and then fix it. The biggest problem was the rental equipment from Lowes. The sales person said they only had 50 feet of hose (not the 100 feet recommended by the manufacturer). I found out when I set up the blower that the hose had been cut and taped together previously and was even shorter than 50 feet. I ended up needing to g...
