First of all thanks everyone for helping with my self build, so much appreciated.

Next stage complete the parapet wall design,roof timbers on for warm roof.My plan is to complete the top of the parapet wall either side,them fix the roof down.

Need to keep the parapet wall to minimum height.

From the attached image could I sit my coping stone ( alliminum copping) directly on the cavity tray??

I'm also hoping to turn my rubber roof up under the coping.

Unsure on parapet wall design lads ?? Always seems to be a grey area.
Woody, I'm glad you replied sure your BC or ex BC, from previous post,Are you in agreement to my above post,is this this possible ?

The only real criteria is the practicality of a 150mm upstand for splash protection,and so that you have room to work and seal the joint below the capping.

Everything else will perform just the same with a low or high parapet.
Thanks lads,so just make sure 150mm minimum upstand..

Thanks for the help again..
