Bathroom Insulation and Ventilation

Bathroom Insulation and Ventilation

Fan Timer Switch

Run the Fan Longer!

A bathroom fan collects the bathroom’s moist air and immediately expels it outdoors. Using a fan while showering but immediately turn it off when done, does not resolve bathroom humidity issues.

The BEST advice I can give you to keep moisture down in a bathroom is to run your fan longer.  The fan must also run long enough to exhaust the moisture.

Fan Controls

It is recommended that a bath fan runs during, as well as,20 minutes after using the shower. One way to achieve this is through the use of a fan timer.

Installing a timer switch will ensure that the fan has time to work by exhausting the room or moist air that is floating in the air after the shower is complete.

Installing Exterior Vent Hood

Vent to the Exterior

Your bathroom fan MUST vent to the exterior of the house via plastic or metal vent cap, with a backdraft damper.  Most vents exit an exterior wall but can also vent out roofs and soffits.

Conclusion

Choosing the best exhaust fan system is an important part of your bathroom remodel. A quality bathroom fan, properly installed will remove moisture and odors from your bathroom which will  improve your indoor air quality.

Remember to take the time to thoroughly understand your bathroom ventilation and insulation needs and make sure that you scope them out in your next remodeling project.
