Large cladding job underway on external building.

The job has a brick dwarf wall, on which is standard 150mm OSB clad timber
frame panels ... this is vertically battened (underway now) then will have
Thermowood cladding (shiplap pattern)

The bottom (1st) run of shiplap will effectively have a gap running along
it's bottom edge, between every vertical; batten .. this I can see being a
very desirable place for spiders, wasps etc.
I can't bock this off as it needs to allow airflow for ventilation, and
water drainage for any rain that gets through.

I need to put some for of insect screen to fill this gap, before I fix first
run of cladding.

Anybody know if I can get a roll (or easily cut sheet) of some form of
insect screen that will last ...... and if so where from.


A Google about has only come across it in the sheets for doors/windows, not
sure if that stuff will last.
