For some reason I am always cold sitting at the kitchen table in our house. My back and the table feel just frigid anytime the outside temperature is below 60. My ever-loving wife, “Francine” (not her real name), on the other hand doesn’t complain as much about it. Her chair is in the middle of the room while mine is near the outside wall. So, being the quick study that I am, after 5 years of shivering I started wondering if cold air could be coming in through the windows or the floor.
Whence the air?
We had replaced the 1923-era windows with triple-pane units a couple of years ago so they really shouldn’t be the source of the cold air. I took a closer look, or should I say feel, and found cold air leaking between the floor and the molding at the base of the wall. This is not a place that anyone talks about as a source for cold air. “Caulk the windows. Caulk the doors. Yada, yada, yada.” But they don’t tell you to caulk the floor.
The cold air was pouring through that crack at the floor. It was also coming in around the outlets near the floor. (If you want to feel for air leaks just get your hand wet and hold it near suspicious spots.)
We have a sun room in the front of the house and it too always seems cold in the winter and warm in the summer. The wooden windows don’t fit very well so I had previously screwed the lower sash to the upper sash of each window to stop some of the air flow. But there was still plenty of air coming in from the great outdoors. Placing my hand along the floor-to-wall molding in the sun room confirmed that even more cold winter air was pouring through those cracks than in the kitchen. Continue reading Air is devious
