Insulation | Vent Chutes & Baffles

Proper attic ventilation and insulation are extremely important in maintaining an energy efficient home or building. The main reasons for keeping an attic ventilated are:

  • Reduce the chance of moisture build-up in the attic or condensation on the underside of the roof sheathing.
  • Make roofing shingles last longer.
  • Lower cooling bills during the summer.
  • Reduce the chance of ice dams.

The success of a vented attic or roof deck relies on its air-tightness. The space above the top plate of exterior walls at the bottom of each rafter bay is especially important. Baffles placed in this area channel intake air into either the attic space or vent chutes, and also prevent insulation from falling into the soffit and blocking airflow.
