    Default Ceiling insulation

    I'm trying to weigh up two options that cost the same - any recommendations?

    We live in Dunedin - cold climate


    1. 6.1R - between ceiling joists - (beams are not covered).
    2. 4.1R - between ceiling joists and 3.2R blanket over ceiling joists and sitting on top of the 4.1R.



    -Thanks!

    Option 2. Without a doubt - Its a no brainer. Helps prevent thermal bridging. Performance will be closer to R - 8.0
