From commercial to residential, no other structurally insulated panels system offers a more do-it-yourself friendly process than RAY-CORE. 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 SIPs. See the Do-It-Yourself Installation Guide.

When Can I Use RAY-CORE Panels?
- Existing structures
- New construction
- Retrofit roof & wall systems
- Basement wall insulation panels
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 raises 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!

RAY-CORE Utilizes Proven Framing Practices
RAY-CORE SIP roof panels & wall 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, double top plates, single bottom plate, headers, king studs, and trimmers for walls will meet all local standard building codes.

On average it will cost about $1350.00 more on a 1500sq foot home to use RAY-CORE's SIP wall panels. This small investment will pay you back in less than three years and keep money in your pocket throughout your life. Read More
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 minimumal 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 panel 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 is the far superior and more reliable solution.
