Hello,
Despite Googling alot I'm unable to find if there is a specific measurement required for building regs regarding overhang when capping a parapet wall with coping stones?
I have a single story extension, double skin + cavity - 2 sides measure 275mm across the cavity and the front measures 290mm. Would a 350mm wide coping do the job i.e. 30mm overhang on on each side on the widest part, or do I need to up to 380mm or 400mm?
Here's what I'm looking at:-

https://www.roofingsuperstore.co.uk...red-coping-stone-600mm-x-400mm-sandstone.html
While I'm at it, can anyone advise what else I need to order for the bricky? I'm thinking I need the following:-
DPC and Cavity Support

Polysulphide sealant - unsure how many I need for 28 Copings on approx 15M run.

Thanks in advance!
