My Attic Does Not Have Baffles

In either case this is nowhere near enough ventilation in my opinion.

My attic does not have baffles.

Basic functions of baffles. This is called passive ventilation. 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. 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.

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. The answer is rafter venting. Things have been ok low energy bills house very comfortable. Fasten blocking around the hatch or door to allow the material to be installed around this area without escaping.

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. 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. Are the two gable vents above or behind the kneewall. If you don t have baffles installed check your intake vents for any type of blockage for insulation or debris.

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. Make sure the fill s depth is uniform across the attic. 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.

Noticed one of the attic vents was not working. 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. Without baffles you must keep vents clear of insulation which means the space around the vent typically receives no blanket of protection. Help purchased home 8 years ago with 2 power attic vents.

Don t be baffled by baffles. Baffles are a critical component to our attic insulation process that provides multiple benefits to a difficult construction aspect. To make it easy to eyeball how level the material is as you blow it in screw depth guides to joists throughout the space. Check your attic for baffles.

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.
