In the constant search for sustainability in the construction sector with the aim of reducing energy consumption, the airtightness of the envelope has become one of the most relevant factors . Unwanted air infiltration has a critical impact on energy efficiency and comfort inside buildings. Therefore, to address this challenge, the Blower Door test is an essential tool. But what does this test consist of and how is the watertightness of buildings measured? Next, we will tell you everything about the blower door test and its importance in the process of insulating homes and obtaining energy certifications such as Passivhaus.

The airtightness of a building refers to the ability of the building envelope to prevent unwanted air infiltration from the outside and leakage from the inside. Without a doubt, it is a fundamental factor that directly affects aspects such as energy efficiency, interior comfort, indoor air quality and noise reduction.
To measure the tightness of a building, different tools can be used, such as the Blower Door test , which allows controlled pressure differences to be created between the inside and outside of the building to quantify the amount of air that is filtered through possible leaks. In this sense, the airtightness rate (n50) is the metric that quantifies the renewals per hour at the pressure of 50 pascals and, the higher the value obtained, the less airtight the space will be. Regulations applicable to the permeability of buildings The importance of the watertightness of a building has been recognized at a regulatory level in many countries. In Spain, for example, the regulations applicable.
