- How to Install an attic bathroom fan and tips on proper insulation and placement of vent hose. I detail how to avoid mold in the attic and explain attic ventilation. Make sure to check my other videos on how to insulate an attic. All videos show how to install insulation in your attic using blown in insulation. The energy savings of increased thermal resistance when properly installed speaks for itself.
I also remove insulation as well as perform attic renovations on new and old homes of various square footage.

Awesome brother.
My brother is a foam sprayer and one of the techniques he uses around the fan housings is he puts a small cardboard box around it and encapsulates it with foam.
I've done this also but with the canned foam.
Good video
that is the way to do it. especially 2 pound closed cell. thanks for watching and make sure you check my other awesome videos 😉. I post every Tuesday.
Cardboard against the fan box or are you creating a dam couple inches away?
Hey man, made another bathroom fan video if you wanted to check it out. Would like your opinion on it. czcams.com/video/7A3zheF-r1o/video.html
This is definitely a great video. I need to make sure my fan is connected right now. Thank you for the video.
You're welcome!
When I buy a house some day, these tips are gonna prove quite useful. Great video buddy!

Hi Pat, just uploaded a new bathroom fan video if you wanted to check it out. czcams.com/video/7A3zheF-r1o/video.html
I'm working on this in my attic. I've learned that it's best for the ductwork to angle down to the vent (on the side of the house). I plan to use semi-rigid ductwork and wrap it with insulation.
Yes well rounded plan so that any condensation does not comme back into your fan and house. I often see them exciting the soffits. But you have to make sure the hose is insulated while in your soffit and has a proper soffit connection. Minimizing the length of the hose is also crucial so the exhaust air exits far away from the house and does not loose too much momentum.
@@SinnisjInsulator I installed a vent cap in the wall, not the soffit. The wall is less than 8' from the fan. I got 4" semi-rigid aluminum duct tubing at Menards, a 4" Y (for 2 bathroom fans to exhaust through one vent cap outside) and will get some sort of insulation wrap for putting around the semi-rigid duct tubes. I am going from old fan with no venting to now trying to be adding the best venting I can. Your attic looks a lot like mine except mine has blown-in insulation on the drywall ceiling. I have to be careful where I step! I put some 3/4" plywood for platforms to work on. Thanks for your video. I found it very helpful.
@@ds61821 thank you for your support on thus channel. I understand you have a flat wall or gable wall on two sides of your house which is where you are exhausting your fan. 4 inch should be plenty. Make sure you wrap that very well and add at least an r32 or 12 inches if loose fill above the pipe even if it's wrapped just to be safe. You can checkout my how to fix loose fill, 5 things to do before insulating your attic and the ventilation video. That would help you even further. I would recommend an r60 for your attic after all is done. That's 22.25 inches of Fiberglass. You can do this stuff on your own of course, just be careful.
@@SinnisjInsulator I'll revisit this once the fans are replaced. My neighbor had his ladder up by his garage and I asked if he would help me install the vent cap on the side of my house. He's young and was happy to help. I had everything ready. But now that the vent is in place I'm buying what I need to get this project moving again. And trying to get it right from the start. Thanks.
@@ds61821 I'm glad I could help. You can subscribe to my channel if you haven't already. I have more videos coming, one every Tuesday.
Great info
Thanks for watching 😊👍. That was one of my first videos. I have a more in depth one linked in the video by clicking on the i icon. It's in the heat loss section 😊
Interesting video :)
Glad you think so!
Pourquoi celui de droite doit être réinstallé? J’ai manqué quelque chose?
je vais mettre les explications pareils à ce que je dit pour les prochains vidéos.
🧑🌾🇨🇦🧑🌾Awesome my friend. Great content as usual!
Thank you kindly sir. Just curious if this was something you already knew or not.
My current exhaust holes is the rigid steel covered with those fluffy insulator, do I need to change them to the flexible holes with insulation around them? Thanks again!
If you model is exiting through the soffit, having the extra wrap won't do much because you will also be putting in extra insulation on top of the wrapping anyway. But also make sure your exhaust pipe is air tight. If it's the rigid one, put duct tape or other tape meant to seal duct work on that seem along the whole pipe. If the pipe is exiting at the roof like in the video, you should definitely get that wrap on the outside. Hope this helps, you can look at the links I provided in the video description to give you an idea what to purchase.
@@SinnisjInsulator It's exiting to the roof. Much appreciated!
@@James_m7 then wrapping with that foil is a must, that way the cold weather won't ruin your wrapped insulation. Those sleeves don't have much r value to begin with.
Here is a super tough insulation job that looks very simple, but is VERY difficult. A 4'x4' skylight taken out of a 100 year old house in the bathroom. Ceiling height about 16', 2x6 rafters, an exhaust fan installed in the cavity. My main concern is moister and rotting. The cavity is enclosed and no air space to rafter. How to insulate? need holes in sides to allow moister to escape, air tight exhaust venting. The exhaust duct has 1" space between duct and roof sheathing and can not bend exhaust like regular 4" tubing to the roof vent, and only 12" pipe run from fan to roof vent. When all insulated, then the ceiling cavity is drywalled. The last thing anyone wants is a hidden rotting roof due to moister build up from the fan leakage, and/or condensation from hot air.
I would try and remove the fan and then put a foam board of 1inch directly underneath the sheathing then putting the fan back. Let me know if that's possible

@@SinnisjInsulator ty for the energy
@@obiedashinobi1322 it's all about supporting ine another. Good luck
Roofers are big time to blame on the bath vents.
One crew removes all the vents. Another tar papers it and another does the shingles.
I dont know how the manufactures can get away with not sealing the fan boxes.
I totally understand, plus putting those plastic covers adds height , therefore even less insulation above the fan box. thanks for the comments.
@@SinnisjInsulator i usually run foil around the seams and extra holes on fan boxes. Extra time. But no air leak. And just insulate right up to it
@@turboflush that's another good way. I unplugged my fan at home from inside my bathroom and ran silicone in all the holes I saw. I didn't want to go back in my attic and disturb my r60 lol. Thanks for the comments.
Hi Turbo, I made a new bathroom fan video if you haven't seen it yet. Sharing info on my job experience and what I notice throughout the years. czcams.com/video/7A3zheF-r1o/video.html
Hiw do you feel /knowledge of blown vs batt vs spray foam roof?
Thank you for that question. You must be talking about just the attic. I'll compare fiberglass batts and loose fill as well as spray foam. Great idea for a new video, thanks for the idea. Batts are typically found in slopped ceiling where loose fill would slide off if stoppers weren't installed. The thing with batts is that they with leave a weak point at the edges no matter how well you install them. They fit inside truss cavities and most of the time leave the trusses bare. Wood only has r1 per inch. Sure you could overlap another layer perpendicular but it depends how easily you can access that area. Attics can be difficult to maneuver. Loose fill fills every gap nicely and provides a more even resistance in my opinion. Spray foam as closed cell foam is obviously the best choice to resisting any heat transfer but is also much more expensive and can be dangerous if not installed properly aka installer installed too much at once therefore it doesn't cure. Anyway I think I'll describe this better in a future video. I have a holiday contest video if you want to check it out.

I am battling between rockwool batt and spray foam the roof.
Both about same cost.
Creatures dont like the rockwool. Batt requires less inches.
I feel that with spray foam it should have a second layer (1" gap ) to remove roof deck heat. I dont think there is wnough infor on spray foam. Advantage is.. The attic becomes similar temp to the house.
Blown in for me i feel is not an option. I go up there every couple years to run wires and random things. Blow in would fill the attic. Makes service difficult.
If i go the batt route. I will probably blow in a couple inches to cover the trusses.
@@turboflush if you are looking to go in the attic after installing Insulation then I would go for rockwool because it is much easier to fix if you need to run more electrical or whatever else. Spray foam is a permanent install and would be a nightmare to remove to run more wiring. If you can, also invest in lumber and build a walkway especially if you have a truss system in your attic. Walkway doesn't have to be that wide. Adding loose fill over batts is a great idea to fill those gaps.
@@SinnisjInsulator the spray foam would be on the roof. Making the attic a conditioned space. Which puts all the duct work in conditioned space.
Maybe not so common up north.
They can spray the ceiling(attic floor) but uncommon.
@@turboflush ok no that would make sense. For a ceiling application I've seen half pound and understand your issue where that would nit allow any airflow if it's sprayed directly on the underside of the roof. You could put cardboard inserts to allow for airflow between the foam and the roof though.
