Any vinyl siding gurus? Question...

[Rookie]

I'm in the process of re siding my house. I just finished the soffet and pulled down the old siding. Behind the siding is a mess. They used the old style "cork" board and left huge gaps. Instead of patching all of it, I would like to cover the exterior with 1/2 insulation board and be done with it. Windows aren't an issue since I'm installing new one. My question is, the J channel in the soffet won't line up with the siding channel if I put on the insulation board - will that be ok?

Are you leaving the old J channel on, or do you mean the new j channel will stick out past the window casing?

 

[littletommy]

Wait, I see what you mean now, no, the j will butt against the soffit channel, as long as you hold a straight line, and use long roofing/siding nails, it won't hurt anything. You should still have a little edge of the soffit channel to butt against, if your using 1/2" foam.

I think the fanfold type stuff is 3/8 thick if memory serves me, shouldn't present any problem.

If you're gonna spent the effort and the time, get fiberglass batts and do it right. I just finished a project that involved taking off insulboard, and installing fiberglass.... go glass

Get everything down to stud level, and the j-channel will line up like it's supposed to.

Thanks. I think I'm going to tear off the old junk and hang osb and then wrap the whole house. Osb or insulation board, which would you suggest?

It has batting in the walls so I'm good there. I was just trying to find a quicker method instead of tearing off the old but I'm going to tear off...

I've always said if I ever built my own house, I would use OSB or plywood everywhere. People don't realize how easy it is to breach a wall by just pulling a little siding loose and kicking through the foam or insulboard sheathing. If it were me, yeah, Osb. As long as you put back something close in thickness to the old sheathing, you'll be fine as far as finishing the top run of siding. I will add, spend some extra time getting your starter run of siding nice and level, and you'll have lots less problems, and as you lock each piece of siding in, on every run, slide it back and forth a little. If it's locked properly, it will slide, if not, well, you get the picture.

This ^^^^ is correct. Siding will warp if not installed properly.
