Noise was an issue i close the closet door to eliminate the hole to the attic effect during the day and i discovered flex duct in 18 diameter is hard to come by.
Attic vent noise.
Climb the ladder remove the access panel and enter the attic.
Remove the current worn out bearings and replace them.
Cut through any sealer that may be present.
Remove the screws holding the vent in place.
Often a stiff wind will open vent dampers causing them to periodically clang shut.
Remove the old vent.
Take for example ridge vents.
Be sure to lubricate the bearings.
This will help to avoid premature damage to the shingles or mold building up in moist hot.
Due to regular wear and tear these bearings can become worn out or lose their lubrication ability.
The vent hood ducts through a rigid or flexible pipe to a cap on the roof or side of your home.
Find the noisy turbine and apply the lubricant to the moving parts of the turbine.
These are located in the track where the pipe coming out of the roof meets the spinning part of the vent.
Attic fans also have small ball bearings that help lubricate the fan s movement.
Well there are three main reasons for noisy vents.
My intention being to move the fan assembly further into the attic.
An attic fan works by exchanging the hot air in your attic space for fresh air pulled through the vents.
Roof vents and power roof vents are made to work in conjunction with vented soffits so that outside air.
The shape of the duct connecting vents in two different rooms to each other is enabling the passage of sound.
Lift up the edges of the surrounding roof shingles so you can see the edges of the vent.
While hardly anybody agrees on the best roof ventilation system everybody agrees some roof vents do hardly any good at all.
If the noise drives you crazy new spring loaded backdraft dampers 9 to 30 depending on the size should solve the problem.
Usually this happens if the vents are straight across from each other so the sound doesn t have to turn any corners on its way between the two rooms.
Place the stepladder under the attic access space.
I have roof vents so i have roof ventilation.
