Laminating accoya to other woods

[tinker]

I need to replace a rotting door frame (external) which sits within a damp wall and will be very prone to rot. I was therefore thinking that accoya would be a good choice. The size of the side jambs will require laminating two pieces of accoya together and this got me wondering about laminating a hardwood to accoya, with the potential aim of having accoya on the external part of the jamb, in contact with the damp wall, and using a hardwood on the internal part what would better withstand dending in a high-traffic area. The thickness of the jambs is in the 4-5" region.

I vaguely remember reading about some attempts to laminate accoya to other woods, both successfully and unsuccessfully. Obviously the main concern would be differential wood movement. Might stress relief cuts help? Does anyone have any experience with this? All thoughts would be much appreciated.

I'd think it would work OK using epoxy glue.

I use Accoya for patching up (softwood - not sure I have ever had to use it on hardwood repairs) and it works very well - yes, easily laminated - I use PU glue; epoxy is also ok for Accoya, but is not so easy to use.

Here is a good example of the sort of thing you describe

In principle it would work, but because the accoya has been treated it does not expand and contract as much as a non treated wood ( which is why its good ). In practice this can cause problems, at the minor end you will see the join as the other wood expaands more, at the extreme end it could cause warping like a bi metalic strip in certain conditions.

I would either go full accoya or try another way to keep it dry like fully surround it in dpm or something.
