Installing the Bathroom Exaust Fan

I’ve recently finished installing my bathroom fan system.  Rather than have an individual ceiling fan in each bathroom, I’ve installed a single remote fan to ventilate both bathrooms.  The fan is installed in an area away from the bathrooms and exhausts out the roof.  This results in a quiet and efficient system.  I’ll put in a timer switch in each bathroom, so the fan can be set to run for 5 – 30 minutes and then shut off automatically.

The white vent pipe you can see in the photos is 4” PVC pipe.  I’ve used the rigid PVC pipe rather than the flexible accordion-style pipe because the PVC pipe walls are smooth, so there is less air resistance than in the flexible pipes.  The pipes run from both the bathroom ceilings to a Y-fitting on the intake side of the fan unit.  The fan exhausts through a 6” diameter pipe to a roof vent.  The 6” pipe is flexible aluminum pipe, but it’s only two feet long so there isn’t a lot of air resistance to deal with. 

The fan I used is a Fantech FR 150.  It’s rated at 263 cfm, which should be plenty for both bathrooms.  It’s amazingly quiet.  Even when standing right next to it, you can barely tell that it’s running.  All you can hear is the air rushing through the pipes. 

Here’s a link if you’d like more information:

The ducting connections to the fan are sealed with aluminum duct tape.   It's different than traditional duct tape; which will dry out and peel away.  This is actually made of thin aluminum and will last for the life of the fan.

Roof Vent For Bathroom Fan

I've installed the roof vent for the bathroom fan system.  I removed a couple of shingles and cut a round(ish) hole for the vent. 

The top of the vent flange is tucked up underneath the roofing felt, and the new shingles get installed over top of that. I've used silicone sealant underneath the top and sides of the flange to ensure a good seal as well.

Loft Insulation

I've been installing the pink insulation baffles in the loft area.  Their purpose is to ensure an air space is always present between the insulation and the bottom side of the roof sheathing.  That air space is essential for proper roof ventilation.

Insulation Progress

Today I installed the insulation and poly in the bathroom walls and ceiling.

More Lights Installed

I have finished up a bit more wiring and installed a few more lights.  The half-bath wiring is done now, and the lights over the stairs and in the loft are installed. 

These are all just temporary light fixtures; I'll eventually install an appropriate bathroom light and some sort of pendant lights over the stairs and in the loft.

Siding Progress

I've finished up the siding and soffits to the peak of the roof on this side of the house.  All that's left to do is the fascia.
