External cladding board

[HughF]

I’m considering my options for replacing the square edge oak cladding on my ‘shack’ (see attached photo)… the wall construction is 4x2 on 16” centers, with building paper on the outside and wood fibre insulation board on the inside.

 

What would people do in this instance, 11mm OSB -> house wrap -> batten -> cladding?

 

I’ve been considering going straight over the top of the 4x2 with insulated industrial wall panels, I’ve also considered importing half a container load of 16mm metal/pu cladding from China, and I’ve considered going for regular wriggly tin… I’ve also considered whether the coated OSB from the US (zip system) is available here, as that would be an ideal product to go underneath whatever surface finish I apply.

 

The current square edge oak is warped in places, and rotting in other places.

 

Is render board and render the correct answer here?

 

Open to ideas and options.

 

*yes, I’m replacing the windows soon

If were me, I might replace any v dodgy wood like for like and maybe consider a coat of Bedec barn paint. Maybe I’m biased as we’re just about to clad our place with oak featheredge. What’s your overall objective - aesthetics? Better insulation? Reduced maintenance?

[HughF]

The overall objective is to replace the damaged stuff and at the same time increase the weatherproofing, whilst having something that is low maintenance. There are sections where the oak is deformed to the point of the hornets find every gap and nest in the walls…
