The F-channel is a thin vinyl strip that is sold where siding is sold. The upside down F creates a shelf for the soffit to slide into and rest on. The F channel can be easily confused with the J-channel that is used to cover the ends of the vinyl at the corners of the house and around windows.
What is the difference between F Channel and J channel?
Typically, builders prefer F channel for soffit, since it’s designed for the purpose. Because it’s crafted to suit the soffit, it doesn’t take as long to install. If you choose J channel, you’ll have to install twice as many pieces, both to hold up the soffit and to cover the edges.
