GLASTA Features

Features

  • 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
GLASTA Wall and climate conditions

Wall and climate conditions

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

Calculation methods

  • Glaser method (EN 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
GLASTA Report

Report

 

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