Advice please - R4/R5 for roof insulation? We have double glazing and was wondering if we need the maximum...
We live just on the cusp of foothills (Stonyfell) so it is colder than down the bottom of our road so to speak..
We do not have insulation in our house atm
Thanks for reading and for all those who commented on my previous posts on this subject.
PS does anybody know how much 12 'downlight covers' should be? got a quote of $264 inc GST thought this was expensive...the remaining lights are LED
