    Hi

    I live in a dormer bungalow, and earlier today lifted a floorboard - actually 18mm chipboard and there was quite a breeze running through it - i guess that is not desirable?

    Also i notice the external cavity walls are open at the tops - i can look down into them.. is that right? I can see the insulation.

    Thanks

    its very desirable to have ventilation to stop the wood rotting under the floor and in the roof
