Insulation Tips
Insulating my granny flat
Nov
Does my granny flat also need to be insulated? In most cases the answer is yes. How much R-Value which you need in the ceiling and walls will depend on a number of factors, primarily the local climate, and the proximity of any other buildings or trees which may provide shading from direct sunlight especially during the hot summer months.
A minimum of R2.5 ceiling insulation is considered necessary in most climates. This may also be adequate in hotter climates, if the granny flat is situated so that it receives direct shade from nearby trees or buildings for most of the day.
The walls should also be insulated. Consider using a combined thermal and acoustic insulation in the walls – this helps to block out unwanted noise transfer, and can make the granny flat more attractive to a potential tenant.

I do not have any trees shading my granny flat. I feel it needs insulation as it is FREEZING in winter but HOT in summer. I have been here for 1 year and need to know I will cope better in the future.
