Material Change of Use ‘conversion’ #buildingprojects have specific considerations when it comes to acoustic insulation and managing the transmission of sound between properties.
Remember a #conversionproject is not the same as a #renovationproject :
- CONVERSION: the purpose of the building changes on completion
- RENOVATION: the purpose of the building stays the same, just updated, upgraded or #remodelled
The distinction is important because the #buildingregulations covering all four UK nations specify different requirements for each.
Material Change of Use or conversion projects must meet minimum #acousticperformance standards for separating #walls and #floors. Renovation projects do not need to comply with these same standards, but that doesn’t mean #soundinsulation between rooms can be ignored.
As with new build, the minimum acoustic performance standards for Material Change of Use projects are inadequate so it is important to go beyond the minimum. And Robust Details is not compatible for Material Change of Use projects.
To pass building control requirements in Material Change of Use, measures will need to be taken to address the transmission of #airbornesound and #impactsound, as well as flanking sound that can transmit around the installed #insulation.
One effective solution is to apply a fully tested acoustic system to the floors and ceilings in Material Change of Use projects - like the Hush Acoustics HD1013 Hush-System 2003 Plus.
The HD1013 system combines a number of Hush Acoustics insulating materials to prevent sound transmission:
- Hush Panel 28 acoustic floor panels with resilient layer
- Hush Slab 100 absorber slabs for fitting in ceiling voids
- Hush Resilient Bar ceiling system
Where an upgrade is needed for a listed building, a better system to use is the HD1030 Hush-System LP. This has been designed for use where an ornate lath and plaster #ceiling is in-situ and is to be retained without damage.
For separating walls, the HD1055 acoustic system for masonry walls with a stud lining is a great solution. By creating a separating wall next to a solid wall, separation can be provided to stop sound transmission paths between adjoining properties.
Where space is at a premium, the HD1041 Hush Wall Lining System offers an acoustic improvement without encroaching excessively on the room space. One of the thinnest sound insulation solutions for walls, this uses Hush Resilient Bars, Hush Slab 25 absorber and Hush Multi Panel as part of a complete system to deliver impressive results.
