Understanding 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 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.

RAY-CORE Utilizes Proven Framing Practices

RAY-CORE SIP roof & 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.

Can I Get OSB On My Panels?

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