The Bar Has Been Raised.
As the leader in the SIP panel industry, it is our responsibility to not only build a quality product but to build a product that will outperform and outlast all other insulation products under the toughest conditions.
Let's Compare Common Insulations
As with any insulation (cellulose, fiberglass, polyurethane, and polystyrene a.k.a. EPS or XPS,) as 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 comparison is 75°F. The per inch R-values below are in accordance with the ASTM C518 Standards at 75°F.
|*R-VALUES AT 75°F||R-Value/ Inch||R-Value 2x4 (3.5")||R-Value 2x6 (5.5")||R-Value 2x8 (7.25")|
|RAY-CORE Polyurethane Foam||7||24.5||38.5||50.7|
|Icynene Spray Foam||5.8||20.3||31.9||42.0|
|Extruded Polystyrene (EPS)||5.0||17.5||27.5||36.2|
|Expanded Polystyrene (XPS)||Avg. 4.0||14||22||29|
Compare RAY-CORE SIPs vs. Sandwich Panel SIPs
|RAY-CORE Polyurethane SIP Panels||Expanded Polystyrene Sandwich SIPs (most common)|
|Douglas Fir Studs (12, 16, or 24 inches on center) centuries old proven structural integrity and standard framing practices and tools.||No studs - OSB and glue provide the structural integrity of the panel (some manufacturers use 2x splines to connect one panel to the next).|
Highest R-Value of any SIP core material (7 per inch).
Lowest R-Value of any SIP core material (3.6 - 4.2 per inch).
|Integrated radiant vapor barrier on both sides prevents transfer of moisture. (.02 perm rating).||No integrated vapor barrier.|
Low perm rating - Impermeable (Does Not Retain Moisture)
|High perm rating of 3 (retains moisture).
High moisture retention Promotes mold growth.
Contributes to rotting.
Allows bacterial growth.
Moisture deterioration delaminates OSB, eliminating structural integrity.
Class 1 fire rated- ASTM E-84.
NOT class 1 fire rated.
No Special Engineering Required. Standard stick framing code and plan requirements.
|Expensive and Extensive Special Engineering Required (this will increase building costs). Not all code jurisdictions allow the use of sandwich panel SIPs.|
RAY-CORE Is Smart
Only RAY-CORE combines the three advanced technologies of studs, high density closed cell polyurethane foam insulation and a radiant foil vapor barrier into one energy saving lightweight SIP panel.
