We are thinking of regibbing our 3 bedrooms and putting in insulation (R2.4) into the exterior facing walls.
In addition will need the walls and ceilings to be plastered and painted. The rooms are not big - probably 3mx4m. Ceiling already has insulation.
We will need new skirting and architraves also.
1. Should I invest in sound insulation within internal walls? What benefits does this really bring?
2. Any ideas how much would it cost for tradesmen to do the job i.e builder, plasterer and painter? Is $6k per room too much?
