Flexospan's FE-66 and FE-12 concealed fastener architectural siding wall panels are among our most versatile. The FE-12 is a 12"-wide, flush panel, with stiffener ribs. (It is available without the stiffener ribs.) It has a clean, flat appearance. The FE-66 is a 12"-wide wall panel, recessed every six inches to provide a shadow effect. The two panels can be used alone, or in combination to create interesting, highly architectural effects.
Both wall panels have concealed fasteners, reducing the number of through-holes and improving water tightness. Both can be used with our FL-24 liner panel to obtain U values as high as 0.65 units.
