Bathroom Vent Fan Ducting Bathroom Vent Fan Ducting
For a bathroom which does not have any opening window, a vent fan is an essential piece of hardware to have installed. These ventilation ducts are there to remove moisture from the atmosphere, thus preventing mold from forming on the walls and ceilings. If you have ever seen a bathroom which has mildew all over the ceiling, it is because there is too much moisture in the room’s atmosphere for too long due to the lack of an adequate ventilation duct. The ventilation duct will be connected to an exhaust fan which will suck the air out of the room. This duct will lead to the outside of the building. Ensuring that a bathroom has adequate ventilation will help to lower the risk of costly renovations in the future and major damage caused by excessive moisture. When you are remodeling your bathroom, this is an ideal opportunity to add a new vent fan system as doing it at a later date will be far more complicated and require more work.
Other Reasons for Installing a Vent Fan
There are various other important reasons for installing a bathroom vent. It also helps to eliminate unpleasant spells by ducting the air out of the room. This improves the air quality as well as helping to prevent prolonged periods of high humidity which causes the mold to form.
Finding the Best Location for a Vent Fan
A vent fan should be located properly for it to adequately service the room. The ventilation duct will have to exit the building and usually the best location for this is somewhere in the building’s attic. The location should also be chosen so that it is between 2 wall studs. Cutting into the beam to install the duct will damage the structure of the roof. A pilot hole will then need to be drilled through the roof and an adequately wide hole then cut into the area for the piping to run through. The fan vent itself should ideally be located in the ceiling of the bathroom or in the top of one of the walls as this location is optimal.
Choosing the Right Vent Fan
Bathroom fans are rated for the sizes of the rooms that they are to be used in. This refers to cubic feet per minute (CFM) of the volume of air removed from the room. Simply put, the higher this figure, the more powerful and effective the exhaust is. To get an idea of how powerful the system needs to be to work properly for your bathroom, you will need to work out the volume of the room. To do this, simply multiply the length, width and height of the room. The recommended air changes per hour (ACH) is 8, which you will need to relate to the volume of your bathroom and the CFM rating of the system that you wish to purchase.
