Ceiling Ventilation Fan
The motor, blower and/or steel housing that encloses them is now causing a louder hum or reasonance because I removed the lining material attach to the walls of the steel housing. The material was falling apart and needed to be replaced. What material is available at the home centers that can be used to re-line the enclosure? I was looking at some foam pads (3/4 thick by 4 inch by 14 inch) that are normally used to block air infiltration on both sides of window air conditioners, but I do not know if its the best material to use. What is the ideal material? I just need enough to line an area of about 14 X 14 X14 inches.
