appearance, remove a 3/4" portion of the nail hem on both sides of the corner post prior to securing. Installing J-channel J-channel should be installed all along the top and sides of window and door casings. Cut j-channels the required length plus twice the width of the j-channel face for overlapping the j-channels at each corner. Place the j-channel against the casing and secure it to the wall, allowing for free movement. To trim the bottom of windows, and at the eave, j-channel can be used with the undersill molding inside the j-channel. The j-channel & undersill combination will secure the cut siding panel and help to keep the alignment straight. Dual undersill molding combines both functions into one part. Cut and secure dual undersill similarly to using j-channels. For Square Corners Start by installing the bottom j-channel, removing a 3/4" notch from each end. Install side j-channels by removing a 3/4" notch from the top, and making a 3/4" drain tab at the bottom. Fold the tab under, and into the bottom j-channel. Install the top j-channel by cutting a 3/4" drain tab at both ends, and bending the drain tabs downward, and into the side j-channels. For Mitered Corners Create mitered corners by cutting 45 degree angles in the bottom end of the side j-channels, and on both sides of the top j-channel. To install, follow the methods described above. Installing the Foam-Backed Siding Panels Lock the insulated panel into the EasyStart strip and slide the vinyl panel
