Riga Technical University (RTU) is in charge of gathering existing information concerning subsequent internal insulation.

The objective is to examine the most common structural elements in historic buildings, determine their physical properties and classify them by different types according to type. Furthermore, the task is to observe and describe the main symptoms of a deteriorating building envelope of a historic building and study their possible causes.

The research includes:

  • survey of historic building stock in the participant countries
  • screening of case studies suitable for internal insulation
  • screening of existing technologies for internal insulation
  • review of existing guidelines on internal insulation.
