   Butt joints....

   Just my opinion though. it's what have done in the past with good results. However, others may think otherwise.

   My take on it is that a scarf joint may open up more during the change in weather.

   Good luck
   Ray :)

   Butt joint might be O.K. for the soffit, since it's not exposed to direct weather,being under the eave, but for fascia I'd go with a scarf joint...it's intended to minimize the gap between boards due to seasonal exspansion and contraction....on the other hand you could just use pvc trim and glue & biscuit the joints!

   P.S. you only need to use a 22 1/2  degree miter for the scarf joint

   I do put up a fair amount of PVC trim and learned awhile back that you better glue the darn things or your just asking for a gap.And the 22 1/2 deg scarf....I'll buy that. I will agree that a scarf joint looks better. just figured that it exposes too much end grain if you don't take the time to glue the thing together. Ray :)

   Hey Ray,

    yup, I hear ya on the glue part of a scarf on wood (exposed grain) and on PVC!

    just curious, your profile says north east, you near bean town?...guessing from the screen name "128" might be rt. 128?

   I couldn't tell you why, but I always used 30 degrees for a scarf. plus lots of glue.

   we do 45  deg. scarf joints.. and  we prime all cuts before we assemble

   same with PVC ( Azek)... only no glue... we want the joint to slip

    a 40 foot one piece Azek is going to tear apart at the weakest point, the expansion & contraction has to be accounted for with the temperature and the exposure ( southern big move) northern ... smaller move )Mike Smith Rhode Island : Design / Build / Repair / Restore

   Scarf joint, always! Use a good exterior wood glue. Use a high quality exterior primer. Prime both sides before hanging fascia. Your fascia will stay straight and your joints won't come apart.
