No, Lowe's wasn't having a Clearance Sale on ventilator grids but I wish it had been! In my world, if a little is good, then a whole lot must be better! Our basement remodelers suggested that we open up the basement with lots of air circulation, so we did.
This is the door to our expanded water room/ utility closet. We removed the clothes closet and took down an inside wall to make a large room for the water conditioning and softening equipment, well pump, and the brand new furnace and air handler. The vents on the left draw directly into the furnace. The ones on the right provide fresh air into the room which can get moist due to condensation on the water pipes during the hot months of the year. I LOVE the little vent in the middle of the door!
These four grids open into a very large storage closet that previously had no air circulation in it. The remodelers said that in order for air to circulate, there must be a high register and a low register. The new heating/ air conditioning vent into the bedroom is directly above this space so the forced air will be able to move in and out of the closet making it less stuffy and closed up.
We even added vents to the doors! The door on the left goes into the newly purposed clothes closet and the one on the right goes into the orange room from which air is pulled into the furnace. To improve over-all circulation, these vents will allow for air to be pulled from this room as well.
Some may think that these vents are unsightly, but they were a practical alternative to purchasing custom made louvered doors in these irregular sizes. The carpenter had to support the frames of each grid with ripped 2x4's because these doors are hollow. A grid is on each side so the door looks finished when open. I like them very much because "form follows function". I just want them to work! We may paint the doors white to improve the appearance.
This is a long view of many of the vents in a row. This basement should show much improvement due to the (over!) abundance of vents helping it to "Stay Fresh"!
