A blower door test is essential for measuring the airtightness of a building and identifying energy losses. At SOCOTEC, we carry out these tests to the highest standards, so you can be sure that your building meets energy efficiency and comfort requirements.
What is a blower door test?
A blower door test is a method for measuring the airtightness of a building. By placing a fan in a doorway and creating pressure differences, air leaks can be easily detected. This is important for minimizing energy waste and comfort issues.
Advantages of a Blower Door Test
The results of the test provide insight into the energy efficiency of your building. This helps you take targeted action, such as improving insulation and sealing, which contributes to lower energy costs and a comfortable living environment.
When is a Blower Door Test Necessary?
Blower door tests are valuable in new construction to comply with building regulations and in renovations to evaluate energy efficiency. They are also often used after maintenance to measure the effectiveness of improvements and in cases of draft and temperature problems.
The Importance of Air Tightness
Air leaks cause unnecessary heat loss, leading to higher energy costs and an unstable indoor climate. A blower door test can detect small leaks, giving you a clear picture of the air tightness and allowing you to make more effective improvements.
After the Test: Analysis and Action
The results of the blower door test are analyzed, and SOCOTEC experts provide you with concrete recommendations to improve airtightness and energy efficiency. This helps in planning insulation and sealing projects aimed at cost savings and comfort.
