2 Story Home Construction
Thought may be considered in terms of acoustic noise reduction when constructing a multi-level home namely, the under floor between the ground and 1st floor.
Installation of spray foam to deaden the noise from activities above is best planned in the early stages before gyprock ceiling is installed.
Resulting outcomes can range from minus 37 to 40 decibel reduction which is very significant.
Typically, these floor joists vary from 200mm to 300mm.
With spray foam direct to under floor + the air gap assists with this process.
