We recently had our plasterboard ceilings taken down in our mid-terrace 1970's house.
I thought I would be able to add some insulation before replacing the ceilings, and after getting some advice from a family member who had a contact with a "Technical person" at an architects, was all set to place insulation between joists leaving at least 50mm gaps to the roof.
However, the more I looked into things (videos of sweating rooves) the more worried I became about doing this.
The roof has no ventilation and previously had no vapour barrier, has also had leaks previously, but with no long term issues arising from these.
Hopefully the attachments will help explain things (please excuse my diagrams).
My questions are;
Can I safely add insulation to this roof from inside?
if not, do i just put a vapour barrier or a VCL up and then plasterboard?
Do I need to get a Residential Surveyor in to tell me what to do?
Any help and advice with any of this is greatly appreciated and will hopefully help to ease my anxieties about this.
Thanks,
Jonathan
