Not when compared to Expanded PVC Board (Komtex/Sintra), especially if it's 8-10mm+. Then there is the weight, as well as the potential of dents that cannot be dealt with except by filling them in and then coating the entire Material with a skim of Drywall compound.
Basically, it's only redeeming quality is it's being impervious to weathering, and the application of a Exterior Matt Polyurethane or Flat Enamel can tame the Gloss.
Some time back I installed a large, uncut piece in a Theater, w/Side Curtain Masking, and Pull Down Top Masking, It was / had to be painted with Black Flame 1.0, and worked splendidly. But I only used it because a full sized sample was sent to me, and it was heavy and a pain to deal with, so after 9 years, it's never been attempted again. Now that's me talkin', but if it means anything, if it was indeed a preferred choice...or even a acceptable choice IMO, you'd have seen me using it fairly often.
I did toy with the idea of Tiling pieces to create a skin for a Outdoor Drive-In Screen on Maui, but between Shipping costs and the potential of large, heavy sheets blowing around the Island come the Kona Winds. Instead, A Oil-Based Black Flame formula Painted onto 3/8" Plywood secured with 2-5/8" Screws onto a 2x4- 2'x 2' square Lattice Framework secured to Telephone Poles won out. Must'a been a good decision, because 8 years later it's still standing and has needed no repairs or repainting.
