RAY-CORE'S SIP PANEL

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!

SIP Panel Breakdown RAYCORE

A general contractor for over 50 years, Harry Raymond believed that the construction industry needed better ways to build more energy efficient, reducing a homeowner's heating and cooling costs for the lifetime of a home. RAY-CORE's insulated wall panels and insulated roof panels were the answer, manufacturing since 1987.

Polyurethane Foam R-Value

This state-of-the-art foamed in place polyurethane foam produces high R-values. As with any insulator (cellulous, fiberglass, polyurethane, and polystyrene a.k.a. EPS or XPS,) when the air temperature drops the R-value will increases. As the air temperature rises the R-value will decrease. It is important that when you see an R-value that you check what temperature the product was tested at. The apples to apples R-value ASTM C518 R-value comparison is at 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!

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

About Polyurethane Foam

This brilliant polyurethane foam (produced by DOW Chemical) not only produces high R-Values, it controls sound, and ensures an airtight structure. It produces all of these benefits while maintaining a class 1 fire rated standard. RAY-CORE’s quality control standards will not settle for less.

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 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 SIPs are the far superior and more reliable solution.

Stud Layout Options

Put your trust in time tested and proven methods.

SIPs Panels RAYCORE

 

RAY-CORE places integrated doug fir wood studs, with other types of framing members available, into our roof and wall panels.
Stud Positioning:
• 16" or 24" on center studs
• OR 12" on center staggered studs for those concerned about thermal drift

Foil Radiant Vapor Barrier

This paper thin high-tech foil radiant vapor barrier, not unlike an emergency heat blanket, helps to reflect the outside temperatures out and the maintain the inside conditioned temperatures.
