• Multi-layered wall (1D)
• Climates at both sides of wall
• GLASTA calculates interstitial condensation and drying due to water vapour diffusion and capillary water transfer

• Per layer: thickness, thermal conductivity or thermal resistance, water vapour resistance factor or water vapour diffusion equivalent thickness, humidification possibility, critical, maximal and initial water contents
• At external and internal side: surface heat transfer coefficient, water vapour diffusion equivalent thickness

• Monthly (or other periodically) mean values of temperature and vapour pressure or relative humidity
• Climatic database for European locations

• Glaser method (prEN ISO 13788): condensation occurs where the calculated vapour pressure is above the saturation vapour pressure.
  The amount of condensation or drying in the layer interfaces is updated after each climate interval
• DIN Glaser method: corresponds to DIN 4108
• Extended Glaser method: considers capillary water movements due to condensation and drying

• Per climate period: Glaser table and diagram
• Water distribution diagram and water contents evolution
• Automatic report generator
• Animations of successive Glaser diagrams (AVI files)
