Is it safe to hang a decorative curtain in front of a wall vent?
That could be potentially hazardous!
you can hang a curtain in front of an air vent, BUT --you ll have to buy one that has been treated with a fire retardant finish, also never hang a plastic curtain in front of it, most air vents do not put out enough heat to start a fire, but the hot air will discolor the curtain over time
has long as it dos not completely seal the vent you should be cool inless it is electric and it will suck the curtain over the vent if you know what i mean
Um you can.... but you'd better take some precautions and accept that the curtain is going to act like a filter and collect a lot of dust. Here's what you can do: 1. Get two sets of curtain rods and mount them above and below the vent. Make sure that the brackets you choose can extend at least 3 inches away from the wall (further is better). Also, make sure that you place them so that the curtain will be as tight as possible (no fluttering/sucking motions when the vent does its thing). You will need to wash the curtain regularly, so pick a durable, but light/thin fabric. 2. Get a hanging decor curtain -- beads, shells, etc. (link below). Pick a material heavy enough so it won't get sucked in (suction may be slight, so bamboo will be fine, or be strong and even shells may move). They'll still get quite dusty, but just do it regularly or hose them down now and then. Of course, hang them as far away from the wall as possible...
