    Ok so walls are chased,
    Windows are scheduled to arrive 11 august, and 1st fix is well underway.

    Before trunking and boxes are laid, would it be worth it getting this paint into the boxes of the outside walls, Ovo there's no need on internal walls?

    Anybody able to lend a man some knowledge?

    Is there something better to consider?

    I think the perceived wisdom is to make the boxes airtight rather than the chase behind them. You should (by rights - most people don't) get air-tight back boxes. There there's a special pumped product (the details escape me) that you squeeze around the wires into each trunk/conduit leaving the box therefore sealing the back box inside the air-tightness envelope and the conduits outside of the envelope.

    I can see the merit in your idea of making the chase air-tight though. You still have to address the point where the conduit penetrates the AT layer at some point though.
