So i see this 1946 house here in fl today.
Attic insulation blocking soffit vents.
Baffle allows airflow and prevents insulation from blocking airflow.
It s a very small house barely 1200 sq ft.
Accuvent original attic soffit vent systems fits 14 5 inch x 41 inch soffit areas 16 o c.
Never cover attic soffit vents with insulation use rafter vents and soffit vents to maintain airflow.
I presume that it has the soffit vents but after being in the attic i see that the insulation is blocking the soffit.
Alternatively use two half sheets of 3 4 inch.
Lay strips of 3 4 inch plywood that are at least 24 inches wide across the floor of the attic.
The most common mistake homeowners make when installing insulation is to block the flow of air at the eaves.
Someone added a ridge vent.
How to keep blow in insulation out of soffits.
You need one baffle for each.
Set the baffles inside the attic opening along with a loaded staple gun.
The soffit vents are now installed but you still need to make sure there s no insulation blocking the new vents.
Unblocking wood blocked soffits is labor intensive i ve done it we either remove the blocking entirely or cut most of it away followed by providing soffit intake venting and using baffles as needed to avoid blocking the openings with insulation.
It still has the old gable vents.
Climb the ladder and inspect the vent openings.
If there s blown in insulation like ours rake back the fluffy stuff with a 3 or 4 ft long 1 x 6 or use a garden rake or hoe.
Homeowners can too easily inadvertently block them when insulating the attic.
If the attic is insulated with fiberglass batts just pull back any that are blocking the flow of air.
Insulation stuffed into building eaves.
Perforated soffit vents over solid wood.
Many older homes have had exterior siding and soffit coverings installed.
The insulation will resist heat transfer into the house.
For the same reason insulation shouldn t touch the roof s underside.
While effective at pulling in cooler air the biggest problem posed by this type of soffit vents is their positioning.
If you see insulation unscrew the vent covers with a screwdriver and push it toward the center of the attic space.
Here are some examples of blocked intake venting in an attic.
