A 25 year old company 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 $1350.00 more than fiberglass).
  • Extremely lightweight (no cranes necessary).
  • Decrease utility bills by 40%.

With benefits like these, it's no surprise RAY-CORE was business of the year in 2011.

When Can I Use Roof Panels?

  • Vaulted, open-beam roof applications (vented & non-vented).
  • Air conditioned attic spaces.
  • TJI roof systems.
  • Truss roof systems.

Utilizes Conventional Proven Framing Practices

RAY-CORE SIP roof panels combine three labor tasks into one smart panel system. This system utilizes conventional proven building materials: premium doug fir members, state-of-the-art rigid polyurethane foam, and foil radiant vapor barrier. This brilliant panel coupled with jobsite materials, rafters for roofs, will meet all local standard building codes.

Do-It-Yourself Friendly

From commercial to residential no other roof panel system offers a more "do-it-yourself" friendly process than RAY-CORE SIPs. With super lightweight panels and easy instructions, if you can pick up a hammer, then you can tackle the most difficult projects and use RAY-CORE. Read More. SIPS PANEL

Very Afforable

RAY-CORE is the most affordable structurally insulated panel on the market. This small investment will pay you back in less than three years and keep money in your pocket throughout your life. With returns like that you can’t afford to go without RAY-CORE roof panels on your next project.

RAY-CORE Panel 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.

3.5"= R26 @ 50°F
5.5"= R42 @ 50°F
7.25"= R52 @ 50°F

Standard Panel Features

RAY-CORE SIP Panels Dimensions:
Standard thickness: 3.5",5.5",7.25"
4' wide and up to 12' in length (*custom sizes available)

1. Foamed-In-Place Metal or Wood Studs
These integrated studs are standard dimensional lumber dimensions that you would find at any building supply center. Unlike traditional sandwich SIPs, your home's structural integrity is not relying on the strength of glue and OSB. You can have peace of mind knowing your roof is resting on solid wood, LVL, or TimberStrand studs.

Stud Layout Options:
• 12" on center staggered studs
• 16" or 24" on center studs

2. Foil Radiant Vapor Barrier
This paper thin high-tech foil radiant vapor barrier, similar to an emergency heat blanket, helps to reflect the outside temperatures out and the inside temperatures in on any structure.

3. Rigid Polyurethane Foam
This state-of-the-art polyurethane foam produces high R-Values, sound control, and ensures an airtight structure while maintaining its class 1 fire rated standard. RAY-CORE’s quality control standards will not settle for less.
Only RAY-CORE combines these advanced technologies into one energy saving SIP panel.

Can I Get OSB On My Panels?

Yes roof sheathing can be nailed to the integrated wood in the factory, although it is recommend to be nailed on at the jobsite. This allows for the OSB or plywood to overlap the panel joints insuring a stronger airtight roof system.

*Unlike most sandwich panels, RAY-CORE advises against injecting polyurethane foam directly to the OSB board. When OSB gets wet during installation or from roof leaks, ice damming, condensation or other common roof problems, it begins to swell, grow mold, mildew, and break down. This swelling diminishes the integrity of the sheathing requiring it to be replaced. If the OSB is glued to the foam the whole panel has to be replaced in order to fix the damaged roof decking. This is the case with other SIP sandwich panels. But with RAY-CORE, simply pull up the damaged sheets of OSB and replace them. RAY-CORE is the far superior solution.
