I'm starting a new build and plan to install a downdraft hob on the island. To extract to the outside (~3m away), I'll need to bring a 220x90mm duct or 150mm diameter duct under the kitchen floor to the outside.
What's the best way to exit the outer wall (150mm cavity)? I guess I either bring it up inside (behind some kitchen cupboards) or bring it up upside?
House will be air tight so will have to consider something like a thermobox I reckon.
Any suggestions/help appreciated
