Mk 1 Ship Lap Type Wall Cladding With White Board Edge Off Cut (WBEOC) 

Strips are fixed with 3.9 screws to Composite Door Edge Strip (CDES) uprights & cross beam.

 I experimented with Lumberjack PU glue to try & seal joints, but the gap was too large. Silicone sealant may work / alternatively coat back with expanding foam to seal & insulate more.

Discussion was had re: whether gap for ventilation (like louvre shutters / doors ) may be useful in hotter climates.

Edge with mdf core at end & sides is exposed to rain. We laft a test panel in Uk weather for a yr & it expanded only slightly at edge. It appears that the glued plastic & polystryrene  / foam composite keeps it in place.

Coating the back edge with paint if left exposed would be advisable.

however, the corved edge may trap water allowing it to settle deeper inot the mdf. A drop of paint or white silicone sealant may stop this

few screws added (sealed with silicone) to stop expanding foam pushing sheet & beams apart

closeup of end screw, perhaps should have washers

Scrap Polystyrene put in 2 parts of panel to save foam (other part left clear as its the window)

Polystyrene forced  into ridge gaps to stop expanding foam escaping into window space

Expanding foam applied , along with one scrap panel of mdf / polystyrene

Poly appears to stop foam creeping / leaking

60cm wide Turkey size aluminium kitchen foil applied . I used this as it was the cheapest light reflective, fire resistant material I could think of .

This could be an interior finish or see 2 pics below
for extra panels

Close up . 2 strips of foil

Foil applied the other way on smaller part of panel

If required it can be covered in plastic panels, though more insulative, it adds more expense / weight
