SubFoor's Sound School – Part 1

Floor Construction for Quieter Homes

Neither in our homes nor in our office buildings do we want to be disturbed by noise from other parts of the building. By making a conscious effort to reduce noise levels from the very beginning, we create valuable benefits for those who will use the building in the future.

With us at Prästängen Byggsystem, you have great opportunities to achieve a higher standard of sound quality. It doesn’t have to cost more or involve more work. Instead, it’s mainly a matter of choosing the right materials and analyzing your needs to select the right solution and design.

Today, virtually all new residential buildings, offices, schools, and preschools are constructed to meet sound reduction requirements. In many municipalities, it is a requirement that a building’s sound standards be documented through measurements and reports from acoustics experts.

A Brief Overview of Noise Classes

The Swedish National Board of Housing, Building and Planning’s building regulations (BBR) refer to two standards regarding acoustics in buildings:

  • SS 25267 (2004) for residential buildings.
  • SS 25268 (2007) for public buildings.

Noise classes according to the standard:

  • A offers a very high standard of sound quality.
  • B provides a high standard of sound quality (common in new residential construction)
  • C: Minimum allowed in newly constructed housing units
  • Low sound insulation standard (can be used when renovating older homes that have difficulty meeting sound class C).

The acoustic requirements must ensure that both airborne sound and structure-borne sound are reduced.

SubFloor Acoustic Flooring

SubFloor acoustic flooring was developed in collaboration with leading experts and features a screw used in conjunction with a unique acoustic foot. The foot provides damping that reduces impact sound by up to 28 dB.
