Important issues to consider:
- What is the maximum height to which the floor can be lifted?
- What will be the final height of the floor? (Carpet/original floor boards/laminated boards, etc.)
- What kind of noise do you want to reduce? (noise coming out of your apartment or noise from underneath)
- Substrate structure.
- Do you have conventional floor beams or concrete floors? (Is there a void between floor boards and floor slabs to be filled with insulation)
