We are having a screened porch built over an existing slab. The 6x6 columns will be wrapped with AZEK column wrap. I will be building the screen panels 40" x 90" and I would like to use AZEK boards (1x4 for top, sides, middle and 1x6 for the bottom) to eliminate maintenance and rot. I am thinking about 1/2 lap joints or pocket screws and PVC glue for either. I see that there are PVC biscuits available so that could be an option also. I'll mount stops on the columns (glue or screw) and screw the panels to the stops.
Has anyone worked with AZEK material or any other PVC trim in this fashion and if so is there any advise you might give?
Thank you for your time in advance
