Wood covering the microwave vent hole
Our curiosity was satisfied as we peered in on a jagged hole stuffed with a very old beach towel (which we promptly discarded). We also had a chance to see what the house had for insulation in the outside walls. To our surprise we found absolutely no insulation in the walls.

Since the exterior vent will not be removed until we get the house repainted down the road, I thought it best to stuff at least a little insulation in the hole.

Some joint compound, light sanding and a couple of coats of paint made the hole disappear.

Although my craftsmanship is now covered by the new microwave, at least I know there is insulation in one place in this house!
