Full rebuild of our cottage, including bathroom and decided to go with Marmox foam backer boards and will be sealing all the joints with their self adhesive tape but wondered what others have done around the windows? If i was plaster boarding i'd have used angle beads for additional strength. Does anyone do that with Marmox / Wedi boards or just seal with something like the marmox sealant or wedi 610 or even something else?

 

A few picks of progress and the window in question
