SIP ROOF PANELS
RAY-CORE's Structural Insulated Panels SIPs are NOT the conventional Sandwich Panel SIP made up of two sheets of OSB, glued to a solid foam core. RAY-CORE SIPs are far superior - eliminating all the problems associated with traditional sandwich panel SIPs. RAY-CORE takes the proven structural reliability of studs, adds state-of-the-art super insulation closed cell polyurethane foam insulation and wraps the panel with a radiant foil vapor barrier to combine these three technologies into one strong, lightweight, structurally sound, labor saving and easy to use insulated wall panel, insulated roof panel and insulated header system. So easy to use, even a DIY do-it-yourself er can build with RAY-CORE SIPs!
RAY-CORE - Over 30 years of manufacturing superior structural insulated panels, RAY-CORE offers a lifetime warranty on all their SIP products.
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%.
- Least expensive per R-value inch insulation on the market.
With benefits like these, it's no surprise RAY-CORE was Idaho's 2011 Business of the Year.
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 foamed in place 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.
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 utilizing standard framing tools and practices, you can tackle the most difficult projects and use RAY-CORE SIP Panels. Read More.
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's SIP Panels are the least expensive insulation per R-value inch insulation on the market!
RAY-CORE Panel R-Values
As with any insulation (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 insulation is the best performing insulator on the market for cold climates! Equally, it is a standout in hot climates as well!

1. Foamed-In-Place Wood Studs
These integrated studs are standard dimensional lumber dimensions that you would find at any building supply center. Unlike traditional sandwich panel 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, LSL or other engineered lumber studs.
Stud Layout Options:
• 16" or 24" on center studs
• 12" on center staggered 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 insulation 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?
Although RAY-CORE can apply sheathing to the integrated wood studs in the factory, best practices recommend that it be nailed on at the jobsite with only a minimal amount of time and cost. Benefits include a lighter, easier to handle panel, and a substantial reduction in shipping costs. Most importantly, by applying the sheathing onsite, this allows for the OSB or plywood to overlap the panel joints insuring a stronger airtight wall or roof system that saves you money.
*Unlike sandwich panels SIPs, RAY-CORE advises against injecting polyurethane foam directly to the OSB board. When OSB gets wet during installation or the result of wall leaks, roof leaks, ice damming, condensation or other common 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 wall or roof decking. This is the case with other sandwich panel SIPs. But with RAY-CORE SIPs, if this were to happen, simply pull off the damaged sheets of OSB and replace them. RAY-CORE SIPs are the far superior and more reliable solution.
