Bathroom vent fans must be vented to the out of doors. Venting this fan into the attic is simply asking for problems. The excessive moisture will cause condensation on the roof members, insulation and eventually cause mold. It is never OK to vent directly into an attic even if the attic itself is vented.
It is moist, warm, and can remain in that state for quite a while if there is no ventilation. A bathroom exhaust fan is one of the best ways to keep the humidity in your bathroom at a comfortable level and keep mold at bay. Use it in conjunction with a device that measures humidity and you’ll be able to keep your bathroom dry
I have seen some rumours on the interwebs that in Victoria at least that it is a regulation that bathroom exhaust fans be vented directly outside. I haven’t been able to find the regulation (most standards want me to pay to read them). Can any builders comment? PS: Looking forward to moving out of a rental
Building Code Requirements: Openable Window or Exhaust Fan. Surprisingly, bathroom fans are not required by most building codes. All municipalities have different requirements, but a majority do not have a hard line on requiring exhaust fans.
Historically, extractor fans were vented into the attic of the home. Home builders learned from this lesson and began running exhaust ventilation ducts to the outside of the home. For this to work properly, air ducts must be properly sealed, meaning no tears or holes that would allow moisture to escape into
A bathroom fan does not need to be installed in a ceiling; it can be installed on a wall. Venting downward respects the laws of physics, which allows us to save energy. When a fan is vented upward through an attic to the outside, the stack effect encourages warm, moist air to continually exhaust because the
There are two kinds of sinks that are commonly used: top-mount and under-mounting. Probably the most commonly used sink, a top-mount, or drop-in, sink is meant to sit on summit of the counter, as the declare suggests. Generally speaking, most of the sink sits under the counter, when just the rim of it sitting on summit of, and visible above, the counter. Top-mount sinks are standard for lovely much any countertop material, including wood and laminate, as the cutout is definitely covered by the sink and appropriately does not risk visceral damaged by water. They are next less costly to install in a rock countertop, because they attain not require laborious polishing of the cutout edges, as when an under-mount sink. But, the performance is that you cannot wipe water and spills straight from the counter into the sink.
The under-mounting sits underneath the counter. The rim of the sink is unmovable to the underside of the countertop, as opposed to sitting on summit of it. This creates a seamless, tidy look, as less of the actual sink is visible. other advantage is that water and spills can be wiped directly from the countertop into the sink without any obstruction, making it a great, easy-to-clean other for associates Bathroom Exhaust Fans Vented Outside. Under-mounting a sink will usually single-handedly be realizable when a solid-surface countertop, such as stone, and isnt standard when a laminate, as it cannot be unassailable as competently against moisture. These sinks next tend to cost more than top-mount ones.
