‘Glass-tight’ (Dutch: glasdicht) is the stage in the building process at which all window and facade openings have been glazed, so that the building is fully closed against wind and rain on the outside. From that moment the interior is protected and the fit-out can start.
Application
The term is mainly used as a milestone in construction planning. Once the roof is watertight and all glazing is fitted into the frames, the building is ‘wind- and watertight’. Key consequences:
- Dry working — plaster, screed and timber finishes can be applied without the risk of rain ingress.
- Heating and drying — construction moisture can be driven out in a controlled way.
- Security — the building can be locked, reducing burglary and material theft.
In practice, reaching ‘weathertight’ is often a contractual acceptance point between the contractor and the client.
