Glazing on RSJ with sliding doors

26 Mar 2020
Reaction score
United Kingdom
~Vaulted kitchen asymmetric roof single storey extension
~Block work with cavity supporting Catnic type RSJ
~Bespoke glazing (2 x triangular) on RSJ
~Sliding doors under RSJ
~Ali cladding C section over external of RSJ

My concern pre door/glazing install is the detail on the RSJ with the course of blocks, which have been used to give an upper fixing point

Query : weep vents & DPC Needed ?
Take off blocks and put timber with membrane ?
Use Compac foam ??
Keen to protect steel from cold bridging hence trying to avoid having to cut ali cladding with weep holes

Advice great appreciated
