Cedar Impressions
Bay Window Cornerposts
When installing Bay Window Cornerposts, be sure to run
Cedar Impressions Metal Starter to both corners, and install
Cedar Impressions panels from right to left.
Install the Cedar Impressions panels into both the inside and
outside cornerposts. Leave a 2.5" gap on each side of the corner.
Once the panel has been fastened, hook the cornerposts over
the siding, making sure they are locked into the starter strip.
Nail through the top two holes of the Cornerpost.
Continue installing the Cornerpost as you move up the wall.
When you reach the top panel, cut the Cornerpost to length
and nail it with a color matched finish nail.
If the Cornerposts are installed before the siding, you will have to
cut the Cedar Impressions panel to fit. To do this, measure from
the edge of the last installed panel to the edge of the Cornerpost.
Add 1-1/4" to this dimension, and cut the panel to length. Angle
the panel under the Cornerpost and slide it to the left until the
side tabs clear. Then slide the panel to the right until the correct
temperature marks on the panel are lined up. Fasten the panel to
the wall.
