Insulated Headers

 RAYCORE Insulated Headers


One of the poorest insulated parts of an exterior wall is the headers above the doors and windows.  With little more than a few insulation r-values for this space, its much like having a 12" high by 38" hole above your door.  Just think how much space all the windows adds up to!  RAYCORE has found a solution for this, offering a high R-value insulated header for this space.  See how RAYCORE can save you hundred, even maybe thousands of dollars in heating and cooling costs each year for the life of your home!

 Manufacturing for over 30 years the best Structural Insulated Panel on the market. RAYCORE stands behind its SIP products, offering a lifetime warranty.

RAYCORE Header R-Values *

With most types of insulation, as the temperature drops the R-value increases, but some perform much better than others.  It is important that, when you compare the R-values of different insulations, you know at what temperature the product was tested. In the US, the apples-to-apples R-value standard is ASTM C518, and the test results are reported a temperature of 75°F. In colder climates where your heating costs are high, you might be more interested in the insulation's R-value at maybe 60°F or 40°F or maybe even 20°F.  RAYCORE's custom blend 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!
