PVDF (Kynar 500 or Fluorpon) versus SMP (Valspar Weather XL)

I am assisting with specifications for a large building (roof is about 40,000 square feet) on rural land in Eastern Ontario. The building will be used for public assembly, and will not be used for animal confinement nor will there be any animal contact at all. The slope will be 1:12. It has been suggested that we can use an SMP coating system (Valspar Weather XL). I have read that PVDF is a better system - but also that it is typically used for higher end architectural buildings. Is PVDF worth the extra cost? Thank you for your advice. Mary Ann Pope		Mary Ann Pope 1/17/2018	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/22773/find/
Do you have a specified roofing system/panel that you will be using?		Eric Novotny An informed customer is the Best Customer! 1/17/2018	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/22774/find/
Certainly many people would not agree with me but in my personal opinion, PVDF is always worth the extra cost. That said ... you're in an area of lower UV exposure ... the very low pitch of this roof likely has very low visibility ... so this does sound like a candidate for a loser grade paint system.

The current plans call for a standing seam roof. Thank you.		Mary Ann Pope 1/19/2018	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/22776/find/
Hi Todd and Eric,, Do you have any advice about standing seam versus other systems? Should we consider hidden fasteners for the roof? The cladding will also be metal - but there are overhangs to protect the cladding somewhat. Are hidden fastener systems worth it?

Mary, At the 1:12 pitch you are really relegated to a mechanically seamed standing seam. Other systems will not work at this low a pitch.		Eric Novotny An informed customer is the Best Customer! 1/19/2018	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/22778/find/
Ditto on the mechanically seamed for a 1:12 pitch. Mechanically seamed panels are clip fastened using concealed screws.		Todd Miller Isaiah Industries, Inc. 1/19/2018	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/22779/find/
