The Architect's Corner
The underlying concept to understanding RAY-CORE is to understand its relationship to conventional framing practices. RAY-CORE was intentionally designed to please architects and engineers alike with its simple and conventional design. Superior to conventional sandwich panel or stress-skin panel SIPs that rely on glue and OSB to create the structural envelope, RAY-CORE SIP Panels utilize conventional structural members with high density closed cell polyurethane foam injection molded between the studs, all wrapped up in a radiant foil vapor barrier. Straight, square, stronger and more reliable with no delamination issues, RAY-CORE SIPs will be the product of choice for your next construction project!

The RAY-CORE SIP Panel - SIMPLE
RAY-CORE superiorly insulating closed cell polyurethane foam insulated panels are 4' wide x 8-12' in length and use conventional stud layouts (2x4's, 2x6's, or 2x8's #2 Douglas Fir) with a Class 1 polyurethane foam between the stud cavities, wrapped in a foil radiant vapor barrier. The studs within the panel run length wise and can be 16" or 24" o.c., or a staggered 12" o.c. to reduce thermal drift. Choise of configuration meets the individual needs of the consumer. A true understanding of this basic structural layout can answer multiple questions going forward.
RAY-CORE wall panels are subject to the same rules and limits as conventional stick framed walls and should be viewed as such in all engineering and architectural designs. As a rule of thumb, if you can do it stick-framing, you can do it with RAY-CORE, (and vice versa). All window and door openings are still built on site with headers, king studs, and trimmers. See Master Spec Sheet.
The majority of RAY-CORE structural insulaed roof panel and wall panels are identical in design. For typical application, RAY-CORE panels are to be laid perpendicular to rafters or trusses and fastened to the rafters or trusses. For span and load capabilities, refer to your span charts and load tables. RAY-CORE uses #2 Douglas Fir 2x4's, 2x6's, & 2x8's, 16" or 24" o.c. and to reduce thermal drift offers a 12" o.c. staggered stud panel. RAY-CORE has the ability to replace the #2 Douglas Fir lumber with engineered lumber for greater spans and loads. RAY-CORE does not provide engineering per specs/drawings or provide certified advice on span or load capabilities. When required, this is left to the architect or engineer. See Master Spec Sheet.
