I have these large gaps between my boards upwards of 1/8" directly in front of the toe kick register. The register doesn't have a damper on it, like most toe kicks for some reason, and I can't figure out if the hot winter furnace air is over drying the floor in front of that register. Anyone else have experience with this before? To make matters worse even if I did some cutting and installed a toe kick with a damper it wouldn't do anything because as the duct exit meets the floor, it just blows the air into the space under the cabinet before pushing out the damperless grille. So using a damper won't solve this? Thinking about stuffing some foam board or some I over that hole behind the toe kick. Thoughts please.
