RAY-CORE Header R-Values

As with any insulator (cellulose, fiberglass, polyurethane, and polystyrene a.k.a. EPS or XPS,) when the air temperature drops the R-Value increases. As the air temperature rises the R-Value decreases. It is important that when you see an R-Value you know at what temperature the product was tested. The apples to apples R-Value ASTM C518 standard comparison is 75°F. If you live in a colder climate, you may be more concerned with comparing the 50°F or even 20°F R-Value of the insulators you are considering as many products R-Values drastically decrease as the temperatures drop. RAY-CORE's high density closed cell polyurethane foam is the best performing insulator on the market for cold climates! Equally, it is a standout in hot climates as well!
