Turbine roof vents should not be used in areas where high winds speeds are common, mainly the Plains States. When winds are above 40 mph turbine vents are noisy and have short life spans.

What are your thoughts on radiant barriers? My air duct is in the attic and my joists are the only thing insulated. Radiant barrier or bats on rafters? Open/closed foam cell is not in my budget

[@jubjubs1000]

my father and i just used something like this but it was all mesh and almost cloth like dipped in a covering oil.

[@Johnnyclean]

Good stuff.

I have a large dormer or structure from an extensions of a finished room in my attic which does not has a window. I just re roofed my house and roofers roofed under the metal flashing alone bottom (which is perpendicular to the roof) of this dormer/structure. When bought the house, the shingles were on top of the flashing. How should it be?

Im still trying to figure why rarely see this tech outside of us. Especially not seen in humid hot climates.

I have used a power roof fan for 40 years and has help my central AC, up through the soffit and out the fan..

OK merci

My house has pex water lines in the attic. And one of them froze in the winter. I’m really worried about venting the attic to much what do you do?

[@MrNiceGuyMEGA08]

Insulate those lines if they are easily accessible. Then maybe more blownnin insulation.

Great video!!

[@bkhoavo]

12:08 how does vent pull conditioned air out of the house, huh? Do you air condition your attic?

[@tonesmith909]

Your interior walls aren’t air tight and conditioned living space is not airtight.

[@MikeM-bn2ij]

Through leaks between the 2 spaces like plumbing runs, sewer venting, electric runs etc. pulls air from those types of openings

[@bkhoavo]

10:00 don't listen to him

[@mikem1436]

What he said makes perfect sense. The theory behind attic ventilation is to draw air up from the soffit to cool the roof. Common sense says that a cooler roof means a cooler attic. By having a vent in the side of the gable, air will be drawn in from there. The roof will remain hot. While there will be some cooling in the attic it is not going to work nearly as well.

[@bkhoavo]

​@@mikem1436 i understand how soffit vent works. But how is the air drawn from gable vent any hotter than from the soffit? His short circuit concern is not applicable as the air movement is a continuous on going process. Not like the vent can only draw certain amount of air volume and it must be optimized. Correct, gable vent might not be effective compare to other methods, but it's definitely still better than no gable vent at all.

Soffit gable and ridge vents don't work well together. I had that configuration when they reroofed my house. Heavy rains leaked in through the ridge vent. Once I blocked off my gable vents never had issues. Plus the external baffle ridge vent with open soffits keep my attic less than 20 degrees hotter than ambient temperature year round. There's websites like green builders that explain the science behind venting. Took me a lot of research to figure out but I'm happy I didn't waste money on an attic fan. If I did, I'd still have a hot attic that gets "cooled off" Now, my attic doesn't even hit that temperature most of the time and in winter it's not 40 degrees hotter which wouldn't be high enough to trigger it in that instance. Pretty much everything this video is saying is correct.
