any comment about the insulation thickness 1/2 compare to 3/4 inch?
some shops people told me is kind of wasting money and too kaisu going for 3/4 inch, manufacturer spec is 3/8, going 1/2 already over spec. why still want go for 3/4 so thick?
the aircon technician even tell me frankly said i'm just letting they making more money from me and ended with a big thick ugly PVC trunking.
is using 3/4 inch too kaisu?
