Airtightness and Blower Door Testing in Madrid: Certification and Efficient Sealing

At CleanFinTech, we understand that airtightness is a crucial factor in your home’s performance and efficiency. The quality of a building’s sealing not only affects interior comfort but also energy costs and the environmental health of the space. That’s why we offer an advanced solution to test, seal, and verify your home’s airtightness in a single visit.

Why Is Airtightness Important?

Airtightness in construction is fundamental to ensuring that a home meets energy efficiency standards. Proper sealing minimizes air loss and ensures that the indoor environment remains comfortable and efficient. However, simply stating that a house is sealed is not enough; it needs to be precisely verified.

In Spain, the average air exchange rate in homes is approximately 10 air changes per hour (a/h). This indicates that a significant amount of cool or warm air is constantly being lost, resulting in higher energy consumption to maintain the desired temperature. In contrast, a Passive House must achieve an airtightness rating of less than 0.6 air changes per hour to obtain certification.

At CleanFinTech, we have developed an innovative solution that allows us to quickly and accurately verify and improve a building’s airtightness. In a single visit, through an automated process, we perform the test, seal any potential air leaks, and deliver the Blower Door Certification. It’s that easy, without complications or delays.

How the Automated Airtightness Test Works:

  • Initial Testing: An initial air infiltration test is necessary to determine the specific parameters and adjustments required to achieve the desired airtightness target.
    • Efficient Sealing: The process combines artificial intelligence and sealing nanoparticles.
    • Blower Door Certification: Upon completion of the airtightness test, after achieving the desired airtightness rating, we deliver your Blower Door Certificate.

Airtightness from 10 to 5 is easy, from 5 to 2.5 RH is simple, and from 1.5 to 0.6 RH is a challenge.

Specialized Applications:

  • Residential Buildings: In environments such as computer server rooms, airtightness is essential for fire suppression systems and equipment protection.
    • Server Rooms: In environments such as computer server rooms, airtightness is essential for fire suppression systems and equipment protection.
    • Healthcare: In the healthcare sector, maintaining an airtight operating room with controlled air is crucial for filtering bacteria and viruses, ensuring a safe and clean environment.
    • Fire Control: A good building envelope seal helps simulate and manage the spread of fire within a building, improving the safety and design of evacuation and protection systems.

Benefits of Efficient Sealing:

  • Reduced Energy Costs: Proper sealing prevents the loss of air conditioning or heating, significantly reducing energy costs and improving the efficiency of your HVAC system.
    • Indoor Comfort: Correct sealing eliminates drafts of hot or cold air and contributes to a more comfortable indoor environment year-round.
    • Air Quality: It ensures indoor air free of contaminants and with optimal oxygen levels. Airtightness also helps control humidity and reduces the accumulation of radon and other harmful gases.

At CleanFinTech, we are proud to offer a comprehensive solution for measuring and improving the airtightness of your home in Madrid. Our automated process not only facilitates obtaining blower door certification but also optimizes energy performance and indoor comfort. Trust us to help you achieve an efficient, comfortable, and safe home.

Our solution has been developed to reduce the time spent on final inspections of tapes, repairs to tears or wear on fabric membranes, complex corner junctions, wooden structures, and critical airtightness points, even in renovations or areas where access to the leak is impossible, especially if it is small. It is a dynamic and fast method, but it does not eliminate the need for proper construction and the application of airtightness principles that have been used in Passive Houses or any low-energy building.
