Radius PVC J-Channel

J-channels are now widely used with many different types of siding. There is always a problem though with how to wrap arch top openings with a proper bending J-channel. While our J-channel is not a user bendable J-channel it is made to match your curved shape.

At Custom Curved Mouldings we can produce custom curved J-channels for most any shape curved door, window or other opening.

In the photos below you will see one of our PVC J-channel half round exterior mouldings. This particular half round moulding has a J-channel to receive siding on the outside of the curve and a 1/8″ x 1 1/2″ recess on the back inside of the curve to accommodate a window nailing flange. This nailing flange recess allows the PVC half round moulding to sit flush on the building sheathing.

Contact us for pricing on making a custom PVC or wood J-channel molding for your installation.
