Since 1987, founded in Pennsylvania, and spread to the world, Harry Raymond (a general contractor for over 50 years) believed the construction industry needed a better alternative to building energy efficiently.
Why is RAY-CORE so Smart?
- Easy to use (Do-It-Yourself friendly)
- No special design or engineering necessary.
- Exceeds or meets all codes.
- Affordable (on avg. only $90 more/house).
- Simply cut to fit jobsite requirements.
- Decrease your utility bills.
- Least expensive per r-value inch on the market.
With benefits like these, it's no surprise RAY-CORE was Idaho's 2011 Business of the Year.
Utilizes Proven Practices
RAY-CORE insulated headers combine labor tasks into one smart insulated header system that is ready to cut and install on any jobsite. This system utilizes conventional proven building materials: Dimensional lumber or LVLs and microllams coupled with premium doug fir top & bottom members, and state-of-the-art high R-value rigid polyurethane foam. This superior header is tough enough for any job.
From commercial to residential, no other framing system offers a more "do-it-yourself" friendly process than RAY-CORE headers. With easy instructions, if you can pick up a hammer, then you can tackle the most difficult projects and use RAY-CORE. Read More.
On average it will cost about $90 more on a 1500sq foot home to use RAY-CORE’s headers. That small investment will keep money in your pocket throughout your life.
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!
