SmartBaffle - Maximum airflow. The Bigger Better Baffle

Air flow from soffit to ridge

Ontario, Canada Building Code (similar to the US Building Codes):

  • Prevent loose-fill insulation from blocking the soffit vents to maintain air flow from the vents into the attic or roof space.
  • Minimize air flow into the insulation near the soffit vents to maintain the thermal performance of the material.

Where soffit venting is used, measures shall be taken:

  • to prevent loose-fill insulation from blocking the soffit vents and to maintain an open path for circulation of air from the vents into the attic or roof space, and
  • to minimize air flow into the loose-fill insulation near the soffit vents to maintain the thermal performance of the material.

9.19.1.3. (amended)

  • Except as provided in Sentence (2) below, where venting is provided to a roof joist space, not less than 63mm (2.48″) of space shall be provided between the top of the insulation and the underside of the roof sheathing.

(2)-  Where venting is provided at the junction of sloped roofs and exterior walls and where preformed baffles are used to contain the insulation, the baffles shall,

  • a) provide an unobstructed air space between the insulation and the underside of the roof sheathing, full width of space, that is,
  • i) not less than 25mm (1″) in dimension for 1/300 ratio of attic ventilation to square feet of attic area being ventilated, and
  • ii) of sufficient cross area to meet the attic or roof space venting requirements of Article 9.19.1.2., and
  • b) extend vertically not less than 50mm (2″) above the top of the insulation for 1/150 ratio of attic ventilation to square feet of attic area being ventilated.

(3)- Ceiling insulation shall be installed in a manner that will not restrict the free flow of air through roof vents or through any portion of the attic or roof space being ventilated.

  • i) the use of baffles is recommended especially at the soffit area to be used as a wind blocker.
  • ii) Baffles should be installed to extend vertically about 2” past the height of the horizontal ceiling insulation

Below is a typical installation from the Attic of the SmartBaffle insulation baffle.
