Apartment buildings
We carry out air permeability tests on residential buildings using regulatory sampling.
Buildings with fewer than 30 apartments
Air permeability tests of the envelope and ventilation ducts.
Residential development of more than 30 apartments
Air permeability tests of the envelope and ventilation ducts.
Air permeability testing for apartment buildings
For apartment buildings, RE2020 requires an air permeability of 1.0 m³/(h.m²) or less at 4 Pa. Depending on the developer’s quality approach, the whole building is tested or a random sample of flats representative of each type.
A method suited to housing developments
We draw up the sampling plan with you, then our Qualibat 8711 operators test each flat according to NF EN ISO 9972. Service shafts, junctions between flats and access to common areas get particular attention, as they account for a large share of leaks.
Building envelope and ventilation ductwork
As Qualibat 8721 certified operators, we also measure ductwork airtightness. Both checks are combined in a single visit to limit travel and keep your handover schedule on track.
