VCL Termination

[stu w]

Evening 

 

A question regarding the VCL layer on a single storey timber frame wall.

I have never come across this as always two storey builds or warm roof system with the layer continuing.

Using the picture purely as an example,  the 50mm pir in red , and the VCL (yellow) layer on the warm side .

What is the most common way on finishing the VCL at ceiling level with a cold roof. 

Up and over onto the double top plate , or lap a piece of vcl off the top timber before the roof goes on, to create a seal with the wall layer when installed ? 

Thanks
