Smooth Star fiberglass door with a small pane of glass at the top. Started painting it yesterday in preparation for an installation next week.
The door is double bored for a deadbolt and keyed knob. I noticed on the 2 1/4" H x 1"W x 1/8" deep areas where the 1" edge (or cross) bore is that there were 2 wood plugs in the wood in this 2 1/4" x 1" lock area. Each wood plug is ~1/2" in diameter. Looking at the door standing vertical, the plugs would be above and below the cross bore. The one above it is at 1:00 - 2:00, and the one below it is at 4:00 to 5:00, so they are both toward the front (external) side of the door. These plugs were there for each of the deadbolt and keyed know cutout, so 4 plugs total.
I'm not sure why these wood plugs are there. Is it normal to have these plugs there? Do they in any way compromise the integrity of the door when it comes to the strength of that area, etc.?
Also, since this was a replacement door for the original which came with some of the fiberglass coating messed up, the glass from the original one was removed and installed in this slab. While it is insulated glass, I was surprised that there was no insulation under the PVC perimeter frame that holds this glass in place. I would think that air would easily get in under this frame and thus into the house around the perimeter of the glass.
Is this the way it is supposed to be?
