Membrane - breathable and vapour barrier - recommendations?

[cameronjac]

Hi

I'm on a budget but need both breathable membrane and also vapour barriers.

Can anyone recommend a certain brand and also cheapest suppliers please?

Thank you in advance

I think cromar 3 is quite cheap.

Vapour barrier, any thin plastic sheet will do.

Toolstation have both iirc
