The SR.I™ panels manufactured by Styro Rail Inc. are composed of type 1 [100 series] or type 2 [200 series] expanded polystyrene [EPS] rigid insulation in which 25 mm x 76 mm [1'' x 3''] furring strips are embedded at every 406 mm [16''] o.c. or at every 610 mm [24''] o.c.

SR.I™ panels are versatile and can be used in many applications requiring the fastening of finished material. Install SR.I™ panels on the interior surface of foundation walls, flat and cathedral ceilings in order to obtain a continuous thermal envelope. Ideal when space is limited.
