StarterBaffle creates necessary airflow in rafter bays

What you need to know about StarterBaffles

Each baffle is designed to work with most rafter bays.. The StarterBaffle can be installed in bays that are 16″ or 24″ on center. A simple rotation of the StarterBaffle will align with the rafters and the 2″ flanges will keep the air channel free of debris. The StarterBaffle at the eaves area will guard against insulation blockage.

The StarterBaffle can be installed to seal the soffit insulation as a weather barrier by simply scoring the two side flanges and bending down at the appropriate distance. What’s more is that the StarterBaffle can be installed from the roof or from the inside room or attic. As you can see the StarterBaffle is very versatile and cost effective.

StarterBaffle is designed for use with both 16” and 24” On Center rafters. These stock sizes will fit snuggly in common 14.5″ and 22.5″ rafter bays. These insulation baffles are strong, durable, easy to work with and can be used in new construction or retrofit during renovations.

StarterBaffle is 4mm (thick) and is constructed of rigid, corrugated plastic with four bending routes each route at 2.25” for easy install to both 16″ and 24″ On Center rafters. StarterBaffles are strong enough to support spray foam expanding insulation creating the required air chute most shingle manufacturers require for shingle warranties.

Description:The StarterBaffle is  1/8” or 4mm (thick) corrugated plastic with double bending routes at 2.25” in from each long edge. Each piece can be cut in half for double coverage at the eaves area to guard against insulation blockage in the open attic rafter spaces. StarterBaffle is designed for use with fiberglass insulation, loose fill insulation or spray foam insulation. StarterBaffle will keep the insulation away from blocking the intake air from the soffit. Air will travel up through the chute created by the StarterBaffle.

StarterBaffle is also designed for rugged, unbreakable use and handling.StarterBaffle is constructed of non-collapsing material with lifetime durability. Ease of installation by the contractor is achieved by the design, engineering and technology inherent in the StarterBaffle product. There are many ways to secure the StarterBaffle but the universal method is to use an 8D nail under each side against the rafter, forcing the StarterBaffle flanges tight to the roof decking. Generally one at the center of each piece, one on each side rafter, should be adequate. Only drive the nail about 1” in the rafter which should be enough to hold the StarterBaffle in place.

Continue until the desired amount of StarterBaffle is installed. Follow up by installing the insulation. Insulation should fit loosely in the remaining rafter space to gain the maximum ‘R’ value (winter) and ‘U’ value (summer). No insulation should be in the 2” chute created when bending up the side flanges against the roof deck.

StarterBaffles are designed to allow 2” of air flow between 16” and 24” on center rafter spaces. Wider or narrower rafter spaces can be accomplished by following the directions enclosed with the product. Any installation questions please contact DCI Products at 1-610-622-4455

Question: Can StarterBaffles be installed in other than a new roof?

Answer: They can definitely be installed in existing buildings. StarterBaffle is easily installed from inside the attic also. Because StarterBaffle has a 2″ airspace it bypasses all the roofing nails making is very easy to install. It also spans the entire rafter bay to give full airflow, maximizing the ventilation system.
