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.
My attic does not have baffles.
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.
In either case this is nowhere near enough ventilation in my opinion.
Make sure the fill s depth is uniform across the attic.
Check your attic for baffles.
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.
Manufacturers make baffles in 14 1 2 as well as 22 1 2.
My roof actually does not have a ridge vent but rather soffit vents and then 1 motor attic vent fan.
Keep in mind not all rafter need baffles just those with intake vents at the soffit.
Help purchased home 8 years ago with 2 power attic vents.
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.
This is called passive ventilation.
If you go up into your attic look for baffles between rafters.
To make it easy to eyeball how level the material is as you blow it in screw depth guides to joists throughout the space.
Things have been ok low energy bills house very comfortable.
This creates a natural air flow by drawing in the air from outside pushing it up and out through the vent at the top of the house.
If you don t have baffles installed check your intake vents for any type of blockage for insulation or debris.
Fasten blocking around the hatch or door to allow the material to be installed around this area without escaping.
Without baffles you must keep vents clear of insulation which means the space around the vent typically receives no blanket of protection.
Basic functions of baffles.
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.
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.
Noticed one of the attic vents was not working.
Baffles are a critical component to our attic insulation process that provides multiple benefits to a difficult construction aspect.
The answer is rafter venting.
Don t be baffled by baffles.
