How Proper Attic Insulation Helps Your Roof

How Proper Attic Insulation Helps Your Roof

Your roof’s performance goes beyond durable shingles; it involves a complete roofing system, including ventilation and insulation products. Owens Corning Roofing emphasizes the importance of a well-designed roofing system to maximize performance, durability, and comfort in your home.

Attic Ventilation + Insulation = Fewer Roof Problems:

The combination of attic insulation and a balanced ventilation system plays a crucial role in maintaining optimal conditions in your attic and on the roof deck. This synergy offers several benefits, including:

  1. Extend the Life of Your Roof:
  • Mitigate potential issues like ice dams, premature roofing material failure, wet wood, metal rust, mold, and interior damage.
  1. Save Money on Heating and Cooling Costs:
  • Regulate attic temperature and moisture, reducing the load on your heating and cooling systems.
  1. Reduce Greenhouse Gas Emissions:
  • Improve energy efficiency, contributing to environmental sustainability.

How Attic Ventilation Works:

Proper attic ventilation is designed to remove excess moisture and hot, stagnant air while maintaining conditioned air inside the house. It is a critical component of a high-performance roofing system. The key principles, known as the ABCs of ventilation, include:

  • Ample Amount (A):
  • Follow the International Building Code (IBC) and International Residential Code (IRC) for the recommended ventilation ratio (1:150 or 1:300 with balanced ventilation).
  • Owens Corning recommends a 1:150 ratio combined with balanced intake and exhaust ventilation.
  • Balanced (B):
  • Maintain a 50% intake and 50% exhaust balance to prevent negative pressure.
  • Exhaust vents (ridge vents or off-ridge vents) should be balanced with intake vents in soffits or lower on the roof slope.
  • Control Air Flow (C):
  • Properly air seal and insulate the attic to prevent conditioned air from escaping, ensuring a comfortable home.
  • Seal air leaks and use insulation to control heat flow in both winter and summer.

Benefits of Attic Insulation:

Properly installed attic insulation provides numerous benefits:

  1. Sealing Attic Air Leaks Helps Save Energy and Money:
  • Up to 40% of air leakage can occur through the attic floor.
  • Air sealing and adding insulation can reduce heating and cooling bills by up to 15%.
  1. Effective for Cold and Warm Climates:
  • In cold climates, insulation keeps heat inside, reducing heating costs.
  • In warm climates, insulation stabilizes indoor temperatures, controlling air-conditioning costs.
  1. Contribution to Greenhouse Gas Emission Reduction:
  • Attic insulation is one of the most effective ways to reduce greenhouse gas emissions.

What is Fiberglass Insulation?

Fiberglass batts and blankets, such as Owens Corning® PINK NEXT GEN™ Fiberglas™ Insulation, are made from glass fibers, providing thermal resistance and sound absorption.

How to Install Fiberglass Insulation in Your Attic:

  • Fiberglass insulation is user-friendly, with batts being easy to install between joists or rafters.
  • Owens Corning® PINK NEXT GEN™ Fiberglas™ Insulation is recommended for precision, comfort, safety, and sustainability.
  • Blown-in insulation systems, like the Owens Corning AtticCat® system, are also available for easy DIY installation.

FAQs About Attic Insulation:

  1. Best Type of Insulation for an Attic:
  • Fiberglass batts or blown-in, loose-fill insulation are suitable choices.
  1. Cost to Insulate an Attic:
  • Costs vary based on the chosen material, with fiberglass insulation being a cost-effective option.
  1. Insulation R-Value for Attic:
  • Consult the U.S. Department of Energy’s recommendations and consider local building codes and contractor advice.
  1. Is Adding Fiberglass Insulation Worth It?
  • Absolutely. It helps prevent heat loss in winter, moderates indoor temperatures in summer, and contributes to energy efficiency.
