R-value (insulation)Vacuum insulated panels have the highest R-value, approximately R-45 (in U.S. units) per inch; aerogel has the next highest R-value (about R-10 to R-30 per inch), followed by polyurethane (PUR) and phenolic foam insulations with R-7 per inch. … Straw bales perform at about R-1.5 per inch.More items…

How dangerous is insulation?

There is no evidence currently of long-term damage from inhaling fiberglass particles, and workers who come into regular contact with fiberglass insulation are not considered to be at any higher risk of lung and breathing problems, especially if they wear proper safety attire.

Aerogel insulation offers the highest R-value of any insulating material at less weight and thickness—ideal for construction, refineries, pipelines, and thin-gap thermal barriers.

How much better is r38 vs r30 insulation?

Example: R38 has a U of 1/R or 1/38=. 026 and R30 has a U of 1/30=. 033. So R38 is about 20% better.
