Sturdy, consistent, right for my job.
Would RecommendI needed to create a chick house out of a large dog cage, and this worked perfectly to create walls just high enough to keep the radiant heat and chicks in, and sturdy to withstand pecking.

Works as advertised, Keeps you cooler.
Would RecommendIt works as advertised and the customer service line picks up the phone. I used this on the underside of the roof of a small cabin and it made an immediate and appreciative difference in the heat absorbed from the son. Cabin was noticeably cooler.

16 inch insulation
Easy to work with and because it is thin it was easy to get over top water, sewer, and electric wires in crawlspace area ceiling or loft so wires and pipes are still exposed and can be easily reached verses a thick insulation type wouldnt have fit.
