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.
What insulation gives the best R-value?
The type of insulation with the highest R-Values, with a few exceptions, is rigid foam or panel insulation. Also called “foam board” or “continuous” insulation. Most varieties of this type of insulation consist of expanded foam sandwiched between two rigid panels.Sep 17, 2021
What is the thinnest loft insulation?
Thermablok® Aerogel is a revolutionary advancement in thermal technology offering the thinnest insulation available to prevent thermal and cold bridging. Classed as a Super Insulation, Aerogel has the highest insulation value of any known material with the lowest thermal conductivity value of any solid (0.015W/mK).
What insulation material has the highest R-value?
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.
How do you get high R-value insulation?
To maximize thermal performance, the insulation must be installed correctly. For instance, if loose-fill cellulose is compressed, it loses many of its air pockets and consequently the ability to insulate efficiently. Or if fiberglass batts have gaps between them, they won't perform up to their potential R-value.Dec 7, 2017
