Outside noise comes into the residence through windows, gaps, ventilation openings and the roof/ dormer. All these four sources must be addressed in different ways.

Put double glazing or sound proof glass if possible. Ensure that the windows close without gaps, for example, seal gaps with window tape.

Seal all gaps at windows and doors well: for example, with window tape. Every gap is a noise-crack.

The roof and/or the dormer have to be provided with floating pre-made partitions and a floating pre-made ceiling. Merfoflex is placed completely vibration free from the walls and ground. Here much higher noise insulation values are achieved than by the placing of a fixed pre-made partition.
