Hi all,
We are building a 2-storey home in sydney and we initially thought of getting hebel flooring to reduce the noise transfer between the floors. Since we are stretching our budget a lot, we have asked the builder for an alternative option and this came at a cheaper price
"Provide R2.5 rated 90mm thick Sound control insulation batts to between floor joists on first floor "
Is this a safe option? We have around 40 downlights to our ground floor and i know nothing about insulation and that there is a 10k difference between the two products (hebel vs insulation).
Any advice is much appreciated.
cheers,
