High R Value Roof Building Construction Aluminum Foil Material Insulation

Super High-R Insulation Products, Thermal Insulation ...

Aerogel has an R-value of about R-10 per inch, is 99% air and insulates up to 37 times higher R-value than fiberglass. The material is costly, and fragile, factors that have limited its use in residential construction. Work is in process to produce a less costly version. Barrier Ultra-R super high-R building panels, produced by Glacier Bay, use Aerogel and are rated up to R-30 per inch, or in Barrier Ultra-r™ panels, R-50 per inch. The Ultra-R™ R-50 insulating …
