Blower Door Measurement to confirm the hermetic integrity of buildings

Measurements: hermetic status

Inspections with the Blower Door
measurement device

- Definition of the hermetic conditions in apartments
and buildings to DIN 4108/07 thermal insulation
guidelines by a certified inspector for building
hermetics in accordance with the EnEV
(ordinance on energy saving)
- Definition of the joint permeability coefficients of
windows and ventilation systems in the outer walls
(joint permeability coefficient)
- Inspection of leakage in the
thermal insulation of the outer building shell

Thermography with / without vacuum

	Illustration of the leakage by differential thermogram between 1. and 2.
	Leakage detection with thermography
	Leakage detection with hot wire anemometer
