Title

Re: 100mm underfelt overlap

If the lap is less than 100mm it will not matter, but don't allow gaping holes at the sides of the lapVent units keep everything tight and secure.

If the lap was a lot more than 100mm the top adge would have to be trimmed down to allow maximum air intake.

Other info on the way.
