Plaster boarding

Hi

I am thinking of doing a bit. I was told once the walls are framed and insulated I need to put up plastic sheet over it and board on top of it. Is this correct? Can I do it without using plastic sheet?

Regards

Usually only vapour barrier on studding is against a block/brick external wall. Idea being to stop warm air condensing on a cold external wall causing condensation and mould behind the walls.

What are you hoping to achieve with the plastic sheet ?

I've done it the other way, plastic first then stud with insulation in between and finally plasterboard. Done it on old properties that don't have a damp proof course so that you have interior walls that are warm and dry.

Then I dig a field drain around the property so the ground doesn't hold water and the walls have a chance of staying dry even without a damp proof course.

[edit] beaten to the answer by others.

Hi

Thanks for the replies by the sounds of it I should be ok. It's a stud wall around 1mtr from the external wall. Is it called kooms. The ceiling slopes up towards the loft.

I890 or something the house was built

Hope that makes sence

Perfect sense.

Hi

It was just because someone told me I would get condensation at the back of it. That's all

I was just looking for other people's thoughts
