Attic Venting

Attic Venting

Proper ventilation in the attic is crucial for effective attic insulation. Without appropriate ventilation, insulating the attic is counterproductive. Adequate air circulation in the attic helps prevent moisture buildup and condensation, especially during winter. In summer, attic vent installation helps cool the roof cavity, reducing heat transfer. A well-ventilated attic and roof cavity can significantly increase the lifespan of the entire roof structure.

Installing Rafter Vents in the Attic

Attic insulation is essential for energy efficiency, and rafter vents, also known as baffles, can help ensure complete coverage. Heating and cooling expenditures can be reduced with sufficient insulation. Rafter vents are essential as they prevent insulation from blocking soffit vents, which allow fresh air to enter the attic. This aids with controlling temperatures and prevents excess moisture, which can lead to mildew bloom. A well-ventilated attic means your home has a steady fresh air flow and can prevent potential damage.

We at Canada National Insulation use baffles when installing the vents in roof trusses in Toronto. If the roof is vented, we install the baffles and then blow in insulation R60. If the roof is non-vented, we use spray foam R31 closed cell.

The Problem with Insufficient Attic Ventilation
  • Is the odour of mould pervading your home?
  • Have you found that controlling your heating or cooling has become getting harder?
  • Is your air conditioner operating extra hard or showing signs of wear and tear?
  • Is there evidence of moisture or leaks on your roof?

Professional attic assessments can quickly detect problems with attic ventilation and help you upgrade to a more economical attic.

Canada National Insulation’s professionals believe roof vent installation is integral to insulation. Each attic is unique, and we install customized ventilation to meet its specific requirements. That’s why we provide attic venting installation services before undertaking any work, ensuring that the most appropriate ventilation components are installed throughout the attic. We offer many options, including installing baffles on roof trusses.
