Basically what we found was, there were 4 bags of insulation materials left above the ceiling. The insulation guy couldn't do the job on their first visit as there wasn't enough materials. On their 2nd visit, they brought a few more bags with different colour (yellow instead of pink).
This is the first set:
This is the 2nd set:
This is the 3rd set:
This is the last set:
From below, can see that the pink ones are in R3.5.
While the new yellow ones are in R3.3, I guess shouldn't be much difference.
We haven't install the roof top ventilation thing yet (as shown below) so it's quite hot up there. But they did quite excellent job, with all areas nicely covered.

what is your experience with whirly birds ? do they work. we are thinking of installing evae vents only as my wife doesn't like the look of whirly birds
many thanks
We install it before in our old house and it indeed reduced the temperature a bit during hot days.
Currently during hot days, downstairs always quite cool but upstairs always quite hot.
If you choose the same colour as roof tiles, with 2 storey houses, you rarely notice it as it's so far above the roof top.
