The chickens are now warm
Would RecommendI enjoyed whining the inside of my chicken coop with this product. A staple gun and a pair of scissors, and I added insulated.

Perfect Insulation

The R-21 rating is misleading. Read label itself.
Would RecommendPurchased for use as bee hive insulation; it should work for this purpose. However, the R-21 rating in the product description is misleading. A layer of Reflectix itself is only R-6.6. You must use additional products to increase the R-value.
