Energy Efficient and Compliant homes
Airtightness testing is essential for reducing heat loss, cutting energy bills, and ensuring your building meets legal requirements. Whether you’re a homeowner, developer, or installer, Efficient Energy Homes Ltd delivers certified testing that supports retrofit compliance and improves building performance.
What is Airtightness Testing?
Airtightness testing measures uncontrolled air leakage through gaps and cracks in a property’s structure. These leaks can cause drafts, heat loss, dampness, and poor energy efficiency. Our tests help identify these weaknesses so your building can be sealed for optimal performance.
Certified Testing Methods
Blower Door Testing
- Measures leakage at 50 Pascals using a mounted fan
- Ideal for diagnostic checks during or after retrofit or construction
- Uses smoke pens and thermal cameras to detect leaks
Pulse Testing
- Low-pressure test (4 Pascals) for real-world conditions
- Quick, non-invasive, no sealing of vents or opening of windows
- Perfect for occupied homes and ongoing projects
Why Airtightness Testing Matters
- Reduces heating costs and energy waste
- Improves thermal comfort and air quality
