about R-2 per inch Click to see full answer. Consequently, is vermiculite a good insulator?Vermiculite is a naturally occurring mineral worldwide. In addition to being light, vermiculite chunks are also absorbent and fire retardant. These characteristics make it great as an additive, for example to potting soil. It also makes a good insulating material.Likewise, how dangerous is vermiculite insulation? Vermiculite itself has not been shown to be a health problem. However, some vermiculite insulation contained asbestos fibres, which can cause problems if inhaled. However, if you believe that your home may contain vermiculite insulation, it is reasonable to assume that it may be contaminated with asbestos. Subsequently, question is, what type of insulation has the lowest R value per inch? Comparative Insulation R-Values Insulation Type: R-Value per Inch: Fiberglass (loose) 2.2 – 2.9 Fiberglass (batts) 2.9 – 3.8 Cellulose (loose) 3.1 – 3.8 Stone Wool (loose) 2.2 – 3.3 What is a good R value for insulation?Typical recommendations for exterior walls are R-13 to R-23, while R-30, R-38 and R-49 are common for ceilings and attic spaces. See the Department of Energy’s (DOE) ranges for recommended levels of insulation below.
