UPDATE: After posting this review, Insulation4US called me and I had extra insulation of the correct width delivered by the end of the day. It was frustrating that the whole process took nearly two months, but I understand that mistakes happen and if I had caught it earlier it likely would have been easier to fix. The problem did get fixed in the end, and I have an insulated attic! Yippee! Thank you, Fiona! Insulation4us delivered the wrong size of insulation. I ordered 24" wide and they delivered 16" wide. Because the batts were wrapped in heavy opaque plastic, you can't see the information on the labels until you open them. We didn't discover the problem because my attic has a plywood "floor" and we were placing the batts directly on top, not between studs(or rafters or whatever they're called in an attic). We ordered just enough to fully cover the floor at 24" wide. With 16"wide only 2/3rds of my attic is insulated! I understand, mistakes happen. But when I contacted insulation4us to point out the error I was given a runaround. Yes, I used what they delivered and it can't go back in the bag. But they delivered the wrong width! I proposed the simple solution of sending me enough material to finish the job, 1/3rd of my original order. My customer service representative (Shauna) directed me to a warehouse manager (Garry). Garry told me he would investigate and get back to me, but he did not. I sent another email reminding him of my existence and my partially insulated attic. Nothing. I sent Shauna another email. Shauna told me to talk to Garry. I sent Garry another email, he said he'd get back to me at "end of business". That was two weeks ago. This whole thing has taken over a month. All I want is an insulated attic! 2/3rds insulated isn't worth anything.
