💨 How to Achieve Airtightness in Buildings
Creating an airtight building is one of the most effective ways to improve energy efficiency and reduce heat loss 🏠❄️
Uncontrolled air leakage can lead to:
• Higher heating demand and energy bills
• Reduced comfort and cold draughts
• Poor indoor air quality
• Increased risk of moisture and condensation
Achieving good airtightness starts early, with a continuous airtight layer, well-designed junctions, the right materials, and quality on-site workmanship. Even small gaps around windows, doors, or service openings can have a big impact on performance.
That’s why Air Tightness Testing is essential. It measures how much air is escaping and ensures your building meets UK Building Regulations Part L, helping to avoid costly failures at final inspection.
