Blower Door Test

A blower door test is a procedure used to measure the airtightness of buildings. It involves mounting a powerful fan, known as a blower, into the frame of an exterior door. Once activated, the fan pulls air out of the building. The higher outside air pressure then flows back into the building through unsealed cracks and openings, showing areas where air leakage occurs.

Advantages

Reduces energy consumption by identifying and addressing air leaks, leading to lower utility bills and a more energy-efficient building.

Versatility

- Pinpoints areas where external pollutants and allergens can enter, improving the indoor air quality and reducing health risks.
- Acts as a quality control measure for new buildings, ensuring that the building meets airtightness standards and verifying the quality of the construction work.

Cost Effective

Provides detailed insights that enable targeted insulation improvements, ensuring efficient resource use and maximized thermal comfort.
