I thought that if you install any kind of fan you gotta make sure you have adequate intake or soffet venting because the fan will create a negative pressure and unless your attic is 100% air sealed from the interior, will pull out conditioned air from the home.. or create a positive pressure if using a fan as an intake and will push the hot air into the home...

If your attic floor isn’t air sealed well, you could create pressurization issues in the home. I see it often during my building science investigations. Otherwise, they seem to be nifty little tools. If you’re going to get one installed, maybe mix it with having the contractor make sure the building envelope from the attic plane is sealed.

This advice (powered attic vent) seems to go against current building science practices from people like Allison Bailes, Matt Risinger, Joe Lstiburek, Martin Holladay, and Fine Home Building, among others. Is this advice for a particular situation or climate? I thought the main consideration of venting the attic was moisture control. What about air sealing and insulation considerations? Thanks. I enjoy your video’s but this one confused me.

First step is to keep the heat out. If you can avoid the attic from heating, that is always the better move. But once the heat is in the house, and in the night it is cooler outdoors, nighttime ventilation is definitely a very good move to avoid overheating in the summer. But the control settings need to be tuned to only ventilate when there is cooling demand and when the outdoor temperature is low enough.

Brad - Now if your question is mostly is the fiberglass blowing around going to be an issue, I would say no because pretty much it settles down. I don’t think it’s going to get too airborne and if it does, it’ll just get blown out the vent.

When installing baffles that run to the ridge vent, am I correct in thinking that a soffit vent should be between each rafter. I'm finishing a room above a garage and plan to insulate.
@Z-Ack
@Z-Ack 3 года назад
No theres actually a ratio of the amount of soffett to gable or ridge vent so you dont start exhausting air through the soffett or sucking in air fton the gable or ridge vents.. same aspect as if you installed a gable fan right next to a ridge vent. They would cancel eachother out just cycling air within that space being close together. Im pretty sure a soffet vent every 10 feet is adequate allowing a baffle or gap between the soffett vent and attic not covered up with insulation. And a gable vent for every 500 sq ft of space.. ridge vent specs are different but are listed on tge packaging.. but with soffett vents just make sure to install a baffle or insulation dam to create a place for the air in the attic to vent through that soffett vent. Good way to tell is to go in the attic and turnout the lights and should be able to see daylight at each soffett vent.. if not then it needs a baffle installed at every vent...

@jeremiahmoore4481

Attic should be vented year round. In the winter if there is no ventilation warm humid air from the living space(shower, cooking, the people inside just breathing) will migrate into the attic and condense on a cold surface…. The roof deck. Also Ice damming can occur in a vented attic assembly if the attic is not as close to the ambient outside temp as possible. In my opinion in a vented assembly: make sure air sealing between living space and attic is done, make sure adequate insulation is present, make sure all appliances are vented outside not dumped in the attic, and make sure your attic is properly ventilated. Several roof vent calculators online. I see this mistake all the time when people put trash bags on their whirley birds. It says on the box Do not cover lol.

Wouldnt that create negative presssure and pull in humid air, possibly causing condensation on a/c ducts?
@CrawlSpaceNinja
@CrawlSpaceNinja 4 года назад
The air temperature outside is typically lower than air temperature in the attic. Condensation can form whether your attic is ventilated or not if dew point is at a level to cause ducts to condensate. In most cases, bringing in cooler outside air will help keep attic cool. Making sure your ducts are well insulated and not leaking air should decrease chance of condensation in a ventilated or non-ventilated attic. In some instances, regardless of ventilation, a dehumidifier is necessary as well to prevent condensation. Every attic, situation, and climate are different so it may be worth consulting a local professional to address concerns in your area. Thanks for the comment!

What attic temp is too hot? I’m seeing a max of 120f on the hottest Summer days.
@CrawlSpaceNinja
@CrawlSpaceNinja 4 года назад
There are many theories and opinions of what attic temp is too hot. What I am seeing from most roofers and inspectors is try to keep attic temp within 20 degrees of outside temp. So if it is 90 degrees outside, 110 degrees in attic is great. Keep in mind these are guidelines and in some cases may be impossible to reach without major corrections like radiant barriers, air sealing, etc.

My attic has dozens of round soffit vents fitted with a screen mesh. IMO, the square mesh seems pretty wide. Today I had to seal off a small gap that some paper wasps found near some of the vents. I watched them get confused after the gap was sealed, and I've noticed that they don't go into the round vents right next to the gap even though it seems like they could easily pass through the mesh. I've been concerned that they might figure out they can sometime, and that I should probably get a second layer mesh to add behind the existing. It's just that these are very difficult to reach from inside and there are a lot of them. Is there a special reason they don't already enter this way? Maybe I don't need to do anything? I've lived here for years without issues, but I want to be safe.

We have a ranch style house central NC with a metal roof with a conventional attic with full length soffit and a ridge vent. We also have gable vents at both ends and I have a thermostat controlled power vent in one of the gables blowing out. I have air sealed pretty well in the attic and we have R-49 batt insulation (R-30 one way and R-19 the other way) with the baffles to keep the soffits clear. I have read many differing opinions on what if anything I should do differently. I have seen keep it the way it is or to get rid of the power fan and block off the gable vents leaving only the soffit and ridge vents. Any advice?

A side note from Michael, you should only have 1 type of ventilation, ridge or gable. Not sure which journal, maybe JLC, there was a test if you had both, you will lose the benefit of both. They kind of cancel themselves out. Heat rises so the best one for removing heat is the ridge vent, assuming its of adequate size.

Michael, I have a cape cod house with a double-ridge pole running the length of the house. I believe that there is not enough opening in the ridge to allow the air to escape. The standard maximum opening for a ridge vent is 3 1/4" and if you add 2 - 1 1/2" ridge poles, that only leaves 1/4" gap total (1/8" on each side of the roof). My roof pitch is 9:12. Is there an extra wide ridge vent made that would allow me to cut more of my roof out to have proper ventilation? Thanks

Thanks Michael, very informativo. I have a question about cooling an attic that has two gable openings one in front of the other. Front and back of the house. My idea is to install a gable fan to exhaust hot air and another to blow cool air from the outside. All gable fans seem to be just to be exhausting? Which one is the one to blow air in? Or all is needed is to turn the fan? Your expert advice would be greatly appreciated
@CrawlSpaceNinja

I had a house with 2 gables. I sealed them because they were allowing rain to enter and causing mold around them. After I sealed them I made sure the baffles kept the soffits clear and the ridge vent was good and I installed a solar attic fan. Made a huge difference. I say all of that because installing gable fans may cause a moisture problems. Usually, one is sufficient blowing out. But that depends on attic size. Do you have a local roofer/weatherization contractor you could have take a look? Hope that helps.

I had a wet low spot in front of a high drain. I put a sump pump with sump pit in and a 40 ft long (maybe longer)french drain on the low wall. I attached a 25 foot pump hose and ran it out the house drain. In addition to that I added a GFCI electrical outlet and ran an extension cord from the sump pit area along the floor joist to a position about 20 feet uphill in the crawl space. I bought a $20.00 box fan and put it on a couple of Breeko blocks. I hooked it up to the extension cord overhead making sure no electrical could touch the ground. I change the box fan every couple of years at the Home Depot and use the fan somewhere else where I can monitor it or get rid of it. I also put Breeko blocks around the sump pit to drain area and run a small heater inside the Breeko blocks. It is fire proof, It sits off of the crawl space floor and the Breeko blocks keep the heater off of the floor. It is also plugged into the GFCI outlet. Works like a champ.

Need to research a little more. Understand that soffett vents are at the eves of the roof or bottom of the roof/ attic. Ridge is at the crest of roof.. air goes from bottom to top. Blowing air out of the ridge vent without a soffett venting system will be like having somebody blow at you from across a hot room with no air movement.. you might feel the blow but wouldnt effect anything.. had a buddy install a big ass fan on an attic window he had with only having soffett vents and no gable or ridge venting. When he turned the fan on the first time it blew every bit of blown in fiberglass insulation through that fan into his yard almost where it was sucking the air through the only place it could through what few soffett venting he had.. but is what you should expect putting a 5 foot round industrial turbine fan on an attic window.. he could fumigate the whole house and suck out all of it in a half a minute with that thing.. said if he left the attic hatch open itd close every door it could in the house...

Keep your attic door closed unless your home is naturally ventilated and not air-conditioned. If you're in that situation, it may be better to just open the windows on either side of the attic and close the door.

One of the issues I've heard of is fire in the attic. Besides having sensor and automatic shutoffs, is the ventilation design going to impact safety?

I installed a gable end attic fan this morning. Btw there is currently 1 inch of old cellulose insulation in most of the attic. Yesterday it was 105 outside and 74 inside at 70% humidity outside and 53% inside. Today is the same outside, and 67 inside at 49% humidity. We have no soffit or ridge vents. The gable end vents are 2ft by 3ft each.

I have a double envelope house with a passive solar heating system. It was built in 1980. One feature of this house is that it has two closets on the highest level of the house (on each side) - both containing a couple vents. I believe these are there to allow warm air to leave the house as it rises during the summer. The problem with these vents is that they allow too much cold air in during the winter. When I bought the house, the closets had foam insulation that could be stuffed in the doorway of these closets to help keep the cold air out. But this does not do a good enough job. I'd like to also put some tight-fitting insulation in the vents themselves for extra insulation (I would then remove the insulation in the spring/summer). I'm wondering, can I treat these vents like crawl space vents to insulate or is there a better way? Should I cut a piece of foam insulation to stuff in there? Or fiber insulation? Or both? I feel that my house could be much more energy efficient if I found an effective way to insulate these closet vents. Anyways, being that I am a new homeowner I have enjoyed your videos and have subscribed to your channel!

Hey Stephen Delwiche, Installing temporary insulation in these vents during the winter months would be best practice. Foam insulation would likely be the best solution here. Thanks for watching and have a blessed day

Interesting video. We have soffits in our home and had a ridge vent installed when we built. We haven’t finished our attic space yet (home was built as a cape) so I haven’t had to deal with venting what will be the true attic yet. Good suggestion with the whisper fan.
