older sips
ok, i am looking for some old span tables.
i am looking at a house constructed in 1997 with insulspan sips. the roof panel joint/splines are 8'-0" on center. all the current literature addresses roof panels with joints at 4'-0" on center.
there are some significant defections and it looks like the panels may be overspanned. any help would be appreciated.

look at page 7. how about the splines? are they undersized?
doesn't look like it. the issue is deflection in the panels themselves. i think it is likely the spline spacing.
thanks for the link, unfortunately it covers splines at 4'-0" on center, the in place panels are splined at 8'-0" on center. this is consistant with all the current literature i have seen.
