Sound insulation and airtightness of historic windows
Due to the absence of seals, historic windows usually have poor sound insulation properties and high ventilation-induced heat losses. Sound insulation and airtightness can be improved by installing seals.

Situation
Measurement of sound insulation and joint permeability of typical historical windows before and after installation of seals; analysis of the influence of seal installation on air permeability of the building envelope; preparation of a planning guideline.
Course of action
As part of the project, measurements of sound insulation in accordance with EN ISO 140-5 and joint permeability are being carried out on six buildings. The measurements are carried out before and after refurbishment by installing seals. Four window construction companies specialising in the renovation of historic windows and three heritage conservation agencies are involved in the project. The findings of the research project will be summarised in a planning guide in German and French.
