Airtightness is a key factor in reducing energy loss, improving indoor comfort, and ensuring a building’s actual performance. At CleanFinTech, we conduct Blower Door tests and technical analyses to detect air leaks, verify the quality of the building envelope, and propose improvement solutions tailored to each project.
We work on residential projects, Passivhaus buildings, renovations, and high-energy-efficiency projects where controlling air leakage is essential to meeting consumption, comfort, and certification targets.
What do we achieve with a Blower Door test?
-
Detect unwanted air infiltration in the building envelope.
-
Reduce energy losses and improve thermal performance.
-
Increase indoor comfort and prevent drafts.
-
Prevent condensation, dampness, and structural defects.
-
Verify the quality of execution for new construction or renovation projects.
-
Provide technical data for Passivhaus certifications and high-efficiency projects.

1. What problem do we solve with airtightness? +
A lack of airtightness leads to uncontrolled air infiltration, which increases energy consumption, compromises indoor comfort, and makes regulatory compliance difficult. Through our Blower Door tests, we measure actual air leakage and propose effective solutions to enhance the building’s thermal performance. In this way, we ensure efficiency, durability, and sustainability in every project.
2. Why an R&D project on sealants? +
Proper sealing is key to achieving good results in a Blower Door test and ensuring the building’s energy efficiency. Our R&D project on airtightness sealants seeks solutions that are more durable, easier to apply, and perform better in real-world construction conditions. We validate every advancement with measurable data, thereby improving both the execution and the overall performance of the system.
3. How is R&D integrated with field services? +
We test our sealant developments directly in real-world applications. We measure their impact using Blower Door tests, thermography, and technical diagnostics, refining both the product and the methodology based on data. This integration ensures a direct link between research, practical application, and continuous improvement in energy-efficient construction projects.
4. Do you work only on single-family homes? +
No. At CleanFinTech, we apply our solutions to single-family homes, multi-family buildings, renovation projects, commercial premises, and even industrial projects. We tailor every service—whether related to airtightness, Passivhaus consulting, or sealing—to the client’s specific needs, always maintaining a technical approach and delivering measurable results on-site.
5. Why is it important to measure airtightness using real data? +
Because no building should be considered efficient without supporting data. The Blower Door test provides objective figures regarding airtightness. This makes it possible to identify construction defects, optimize thermal comfort, and comply with regulations such as CTE DB-HE1 or the requirements of the Passivhaus standard.
