Thermal and acoustic performances
People have become more concerned with the problems of climate change. It was realised that this was a world wide problem and so countries were encouraged to set targets for new building regulations to cover improved insulation values.
What are the main changes?
• Lower “U” values for roofs and walls
• Greater consideration of thermal bridging at junctions
Noise in the environment or community seriously affects people, interfering with the daily activities at works, during leisure time, at school, in hospital …
Sound insulation is required in order to eliminate the sound path from a source to a receiver such as between classrooms in a school for example, or to reduce unwanted external noise inside a concert hall.
Sound absorption is required to reduce reverberation and reflection of noise and so increase the acoustic comfort needed in a Hospital or in public buildings.
In the Technical guide is given on how to achieve these requirements with the Arval systems.
