![]() I have windows and a balcony and can regulate fresh air needs. They are solely there for "fresh" air I was told, but my condo abuts an alley and the fresh are is not quite fresh. I just bought a condo and there are two exposed holes covered by grated vent covers. ![]() Regarding, "ducts require exposed holes in floors, walls or ceilings in order to allow heated or cooled air to pass from the duct work to the interior of a building." In then winter when the ac is off i get a draft that comes from my ceiling vents in all rooms why is this and do they sell a cover to place over my plastic vents to keep the cool air out? A home needs adequate constant air circulation and ventilation, otherwise problems such as mold in window frames, cracks in drywall seams and "popped" drywall nail holes from temperature and moisture changes will appear. The reason "fresh air" vents are installed in residences is that current building codes make for much more "airtight" structures then what was built years ago. A dirty/clogged air filter in the system will have a much more dramatic effect on how quickly a home is brought to temperature. The fin direction of vent covers has only a marginal difference to air flow. I would like to find something that is easier to use and not so messy. But I am trying to find a vent cover that will meet OSHA standards for keeping air out when there is a possibility that the air could be contaminated. I am looking for vent covers that will keep air out. Are there any diverters/deflectors that might help? However there is a need for air to be circulating in that area. The ac comes directly down on the altar and creates a problem with the candles etc. I am trying to find something to put over a ceiling vent in an old large church. Once in the past we had a table in this spot and it only took one winter for the wood to split at a seam, Are there diverters that are more tube like so the flooring doesn't have to be exposed to the a/c or heat? I'm worried about the heat in the winter on my hardwood floors. I would like to put a vent diverter under my couch. Don't use spray paint - it could get messy if you are not real careful! If you are really concerned about looking into the cavity and seeing a stud or the backside of sheet rock, paint the cavity flat black. But they may notice dirty vent covers if you don't keep them clean. Most visitors will never notice which way they are facing. Dust will accumulate on the vent cover regardless of which direction it is installed. Dust gets *pulled* into that opening anytime the return is calling for air. But preventing dust from "floating" in the opening is silly. Seeing into the wall cavity may be unappealing to some. Make sure you remove any vent covers before turning on the air con unit at the start of summer!Īnon4732: There is no "right" way or wrong way to install a vent cover. I use them and they work great for the last two years. There's a product called VentSTOP that works on any kind of vent because you use velcro, not magnets. I've seen folks posting looking for ways to cover vents and/or redirect air flow. What is the correct way and direction to install these vents? ![]() I had somebody tell me they are all backward. ![]() Each one is installed so the air flow goes towards the middle of the room, not towards the window. They are installed near all of the windows of the house. I have seen some small magnetic ones in magazines, but not any that would fit a large office vent. ![]()
