Does anyone know what the bulding regs require re ceiling sound-insulation measures when converting a house into two flats (one up and one down)? I recall they recommended fixing plasterboard to the ceiling of the lower flat - but how many layers and of what thickness is effective?
This looks like a difficult job. Can anyone offer any tips on how to do it single-handed with as few problems as possible?
How about finishing? I am definitely not a proffessional plasterer, so what is the most cost-effective way to get a neat finish with no joins visible (and joins that won't produce cracks in the future?
In case I decide to chicken out of this job, how much would a pro charge to do two rooms, each 3m x 5m (fixing up the plasterboard and finishing - labour and materials)? (roughly)
Thank you....
