Installing Baffles In Roof

It is a simple yet functional design with the added bonus of keeping unwanted pests from entering your home.

Installing baffles in roof.

As with attic floor insulation moisture and heat removal are the reasons for creating proper air. Clear any insulation or other debris away from the top of the grate of the soffit vent. Rafter vents ensure the soffit vents are clear and there is a channel for outside air to move into the attic at the soffits and out through the gable or ridge vent. Baffles establish a channel for air to circulate between the insulation and the roof sheathing.

You ll need to crawl to the end of the eave and staple the baffle against the roof deck. The outside edge of the baffle should be parallel to the exterior wall sheathing. Place the baffle so that the open channel which runs along its underside is against the roof. So why install a baffle.

Baffles are easy to find in any diy store. If your roof rafters have been covered over with drywall or plywood you will have to remove it in order to install the baffles. These have to be installed in all the areas where the insulation needs to be held firmly in place. Complete coverage of the attic floor along with sealing air leaks will ensure you get the best performance from your insulation.

To completely cover your attic floor with insulation out to the eaves you need to install rafter vents also called insulation baffles. Place the rafter vent against the underside of the roof with one narrow end resting against the top of the soffit vent grill. Soffit vents and baffles work in tandem together and you will usually find attic baffles between the rafters or the roof sheathing in order to create protection for the soffit vents. Staple each side to the roof deck spaced about every 4 inches.

This is especially important in areas where the insulation meets the ceiling joists and the roof rafters. Step 1 installing the baffles. If your finished attic includes knee walls along the lower sections of the space you only need to install baffles to the area where drywall will be attached directly to the roof rafters.
