🚨 Myth Busting: Does Airtightness Mean Poor Ventilation? 🚨
One of the biggest misconceptions in building performance is that making a building airtight leads to poor ventilation. FALSE! ❌
✅ Airtightness is about controlling airflow, not eliminating it. While sealing air leaks reduces uncontrolled drafts, the key to healthy indoor air is installing controlled ventilation systems that ensure the right amount of fresh air circulates where it’s needed.
🔹 Why Airtightness & Ventilation Work Together:
✔ Prevents Heat Loss & Lower Energy Bills – With a well-sealed building, heating and cooling systems perform more efficiently. 💰
✔ Improves Indoor Air Quality – Proper ventilation removes excess moisture, pollutants, and CO2, ensuring healthier air and preventing damp, mold, and mildew. 🌿
✔ Reduces Condensation – Effective ventilation reduces the risk of condensation build-up inside the building, which can lead to structural damage and health concerns. 🌬️
✔ Ensures Compliance with Building Regulations – Modern regulations require a balance between airtightness and ventilation, ensuring homes are both energy-efficient and comfortable. 🏡
🔍 The Solution? Combining airtight construction with a balanced ventilation system (e.g., MVHR or extraction fans) creates energy-efficient, healthy homes that meet all building regulations.
