Many Passive House design principles are invisible and they are designed into the fabric of the building itself, such as a high level of airtightness. With this in mind, we have developed Portascanner® Airtight, the world’s first micro air-leak detector, which uses ultrasound only.

This is the first time that one instrument can:

  1. Identify leak sites with a microscopic level of accuracy, and

  2. Measure and quantify them using sophisticated algorithms, and

  3. Generate a value for the air flow rate through each leak site, as well as

  4. Calculate the room or building’s overall air permeability and

  5. Store photographic and quantitative data to generate traceable, exportable reports.
