Fypon J Channels? - Contractor Talk - Professional Construction and Remodeling Forum

Hey guys, one of my workers said he heard of buying fypon in sheets, ripping 1x4 trim boards and then rabbitt cut them to use as j channels. The 5/4 with a 3/4 rabitt sounds OK and it may look nice but never did it. Anyone ever done it? Hints? All responses greatly appreciated. Thanks!

Thanks. Any special installing techniques? Do I have to use glue and nails or just nails?

i am pretty sure you can buy fypon sheets with a j already built in to it. why fypon,buy some azek sheets. azek DEFINITELY come with a 3/4 inch j-pocket. azek does not have to be painted whereas fypon does and i also think fypon is more money. more importantly,azek is much more durable. you can also use restoration millwork from certainteed.
when using 5/4 sheets without j,just route out a j with a router bit.

you could also pack out 3/4 stock the siding thickness.Whether you rout out or pack out you should install a metal drip cap to keep any water out of the window head

Side windows are covered by eave so no sweat, but how would I install metal drip edge over rabitted aztek/fypon? I see your point and it's a good one, silicone will not hold up?

The siding will be vinyl, so are you saying I should use one of those tight sill pieces on the top to hold the vinyl piece over the drip edge?

i would and this is just my opinion
