Hi all,
house was built 2 years ago, we have a 2nd floor living space in the "ceiling space" (as it appears from outside) - and have access to the roof space around this.
There is insulation on the external sides of the internal walls in this space - but this area still gets ludicrously hot during summer.
I have installed 2 x solarstars (http://solatube.com.au/roof-ventilation/) and found they made no noticeable difference.
My next thought was to add another layer of insulation - on the "underside" of the roof. It is a colourbond roof, which has a lining of silver material on the underside already (called "sarking" I believe?).
So - to those in the know - would adding another layer of insulation at that location make any difference? and more to the point, does it pose any type of fire risk or contravene and building codes ?
thanks.
