    Default Roof insulation/Whirly bird/Sarking

    Hi everyone,
    I live in sydney, and have calculated that my roof does not need sarking by law.

    Part 1:
    When I go into the garage roof I can see the bottom of the tiles on the roof!
    Needless to say, it gets really hot in there! There is no insulation on the floor.
    I need to just reduce the temp a little in there so I can store some items without them being damaged.

    Should I install batts?
    Should I install whirley birds?
    Should I install sarking from inside and staple to the roof beams?

    Part 2:
    The main part of the house has got a pumped messy insulation on the floor of the roof space, but nothing up in the actual roof joists.
    The upstairs gets cold in winter still, and deadly hot in the summer....Should I somehow change my insulation in the main roof?

    Part 3: The floor on lower level is tiled/carpeted with a large open void under neath (about 3m void)... in summer these rooms are lovely, but in winter, they are DEADLY cold and even the carpet feels icy...

    What can I do for my three areas please!???

    Thanks Edward.

    batts will help to start. look at solar powered whirlies, I have the traditional ones and will upgrade later as they take out the hot air in winter. hopefully your eaves have holes to allow passive airflow.
    cheers Look out if I have a tape measure in my hand.....I'm upto something

    Is there not even any insulation on the top of the ceiling?

    Hi Bob, in the garage area, nope. there is nothing.
    In the main roof there is some messy pumped rubbish on the floor of the ceiling only. But wherever you look up, there is just tile bottoms and joists to be seen.

    Doing the batts properly is likely to help. Also you can get concertina foil batts for in between the roof rafters that may be worth considering. I think you'd probably want to ride it the summer before tying to do an install because it'll be so hot.

    There are some others on here with a lot of insulating experience so should be more advice to come.

    So they are good during summer, but on cold days or nights not so good as you say they take the heat out ? Bugger didn't know that just installed one.

    Mr Fluffy is an asbestos type insulation and house demolition seems to be the only remedy. But was originally considered confined to the ACT.

    This is not good a house we rented has a material like this in the roof. I hope to GOD it wasn't the asbestos stuff or i could be screwed. I had to go up a few times to tend to a leak. Also my parents in the uk have something similar but theirs is "supposed" to be recycled phone books or something like that.

    It most likely is the recycled paper type of insulation, mobs like Cool & Cosy operate everywhere. Sometimes it's possible to tell just by looking at it; there are bits of paper large enough to see some of the printing still visible.

    1990 means old phone books for insulation, Mr Fluffy operated 1960's to 1970's, yours is most likely cellulose fibre (newspapers phone books etc)

    Actually more likely blown in loose fill fibre glass or rock wool insulation which was much more common and around well before batts. Nurseedward should have a read of the Insulation manual in the Forum Library . . . .
