Utvärdering av ytskiktskrav i Br1-byggnader

Sammanfattning: Advice and regulations regarding surface layers in Boverkets byggregler have largely remained unchanged over the past 40–50 years. What are these requirements based on and are they still relevant today? The question has been initiated by the company Ecophon. We found that the regulations are an engineering assessment and is not based on trials or research. The assessment that was made turns out to be well made compared to calculations that we performed. Our conclusion is therefore that the requirements should not be eased.
