Wonderful product. 5 ⭐️s! But very poor service; 0 star. I bought 23, only 15 fits on my truck. Because it was late in the evening, I asked permission to leave the remaining 8 at the store for pickup the next day. When I returned, to my surprise, my items were sold and replaced by opened/damaged items, and no assistance with loading. I am very disappointed and very dissatisfied with service I received at the Lake Park, FL branch. And I am seriously considering not shop at that branch anymore.

Insulation
Would Not RecommendI replaced the pink that had the paper backing I installed 8 years ago due to water damage. The difference was quite noticeable in the time it took to heat up the room without the AC on. JM was more manageable to work with and less fiberglass irritability on the skin when brushing up against it.

Be careful with online ordering.
The product was fine.....lowes service was not. After being told our order was ready for pickup, when we arrived the next morning, nothing was ready and half our order was out of stock.......wasting hours of my contractors time, as well as mine. How could this happen? Some worker lied? Couldnt read the order? Please refer to order #10090213524361.
