Hi!
Due to a steep sloping I'm unable to remove weatheboards to install some much needed insulation (Daylesford, Vic ... cold). I'm willing to remove some skanky palster but I'm unsure which type of insulation type I should use which will be the most convenient and efficient. Any tips greatky appreciated.
Cheers
Michael
Hi Michael,
My first post here - been learning (lurking) for a while :)
We just went through a similar exercise with our old fibro. We cut the foil house wrap to size and stapled in among the studs and noggings, then filled with the appropriate R code CSR gold type glass batts (R1.5 in our area) and gyped back up.
Hope this helps

As dodge said ... but polyester is nicer to work with if you can afford it. 1.5 for walls in my area but you could go a bit higher if you wanted ... but again it will cost a little more.
Have you done the ceiling ... that's where majority will go? Also fill all gaps, old places with gaps get cold very quickly.
I've installed some insulation in the walls from the outside (where I've replaced weatherboards). If I was renovating again, I'd remove all the external walls (either from outside or inside) and insulate the whole thing (including floors where accessible).Quote:

I used Insulco Acousti-Therm R2.5 wall bats. They are fibreglass but I could fit R2.5 in the space inside my wall, whereas the polyester bats I saw that will fit in the same space only are R1.5. You will need to make sure the space inside your wall is big enough for the bats you buy. Your house has probably got 4 inch studs like mine. IIRC to get R2.5 in polyester you need 5 or 6 inches of space. Four inch polyester bats will only be R1.5 IIRC. If you squash it into a smaller space than it is designed for, you will get a lower R value.
Fibreglass is not that bad to work with. Just wear long sleeves and pants or you will get itchy, wear gloves and a dust mask.
There's a map here showing the minimum wall insulation level for your climate.

We can certainly see the effect of the insulation on a cold morning. The dew on the weatherboards all evaporates when the central heating is turned on - except where there is insulation.
