Gypsum Series
Ray Magic® SL
Ray Magic® SL (Slim) is a high performance hydronic radiant gypsum panel. It comes finished with CertainTeed 1⁄2” gypsum board with AirRenew® and is installed within the ceiling to create an unobstructed radiant surface.
Ray Magic® SL is 2’x8′ in size but can be cut down into two 2’x4′ panels to fit smaller spaces.
Ray Magic® SL ships in a two-panel format (4′x8′ in size) that will need to be split into two 2′x8′ panels on site.
The panel consists of a 11⁄2″ thick EPS board with laid down aluminum heat transfer plates with propriety omega shaped channels. Pressed into these channels are two symmetrical 8 mm PEX radiant tubing circuits laid out in a serpentine pattern. Each tubing circuit is connected in parallel to 16 mm PEX return and supply lines that run along the length of the panel. Panels are connected together using slide-in patented fitting technology that allows for internal PEX piping expansion and contraction.

Notes |
||
|
1.
Ray Magic SL is 2’x8′ in size. Panels are manufactured in a 4′x8′ format that included two Ray Magic SL panels. The 4’x8′ panel must be cut along the split line on the job site. Unless differently
specified, all data refer to one single 2’x8′ Ray Magic SL panel (no the package of two).
