My Attic Does Not Have Baffles

Manufacturers make baffles in 14 1 2 as well as 22 1 2.

My attic does not have baffles.

Basic functions of baffles. This is called passive ventilation. Not sure i follow this but it sounds like you have two vents in the gable ends of the attic and three box type roof vents. Fasten blocking around the hatch or door to allow the material to be installed around this area without escaping.

Keep in mind not all rafter need baffles just those with intake vents at the soffit. If this does happen the soffit vents will not function as best as they should and therefore supporting the formation of mold or fungi rather than preventing it. To make it easy to eyeball how level the material is as you blow it in screw depth guides to joists throughout the space. In either case this is nowhere near enough ventilation in my opinion.

My roof actually does not have a ridge vent but rather soffit vents and then 1 motor attic vent fan. Baffles are chutes that when installed properly can provide a channel for air to flow from your exterior soffit vents up into your attic space. The most common way to add ventilation to an attic is by installing air intakes in the soffits and putting an outlet at the gable of the house. Check your attic for baffles.

If you opt not to have an attic baffle you could potentially be leaving your home to additional debris and moisture to enter through the soffit vents. Rafter vents or insulation baffles install in any rafter space to create narrow gaps that direct fresh air from the soffit vents to the peak of the roof. Baffles are a critical component to our attic insulation process that provides multiple benefits to a difficult construction aspect. If you don t have baffles installed check your intake vents for any type of blockage for insulation or debris.

Could it make sense to do site built baffles rigid foam all the way up my rafter bay from the soffit to the roof line so the rafter cavity is enclosed with 2 in gap for air flow of course and then run duct from each rafter bay to the attic. Make sure the fill s depth is uniform across the attic. The answer is rafter venting. Noticed one of the attic vents was not working.

Don t be baffled by baffles. Are the two gable vents above or behind the kneewall. Told that the 2 attic power vents are the only attic ventilation i have the house does have vented soffits every other soffit cover is vented. Help purchased home 8 years ago with 2 power attic vents.
