EWI and removing soffit

[Joseph45678]

I am hoping for some advice please. 

 

We had the soffit removed to run the EWI to the top of the wall to eliminate cold briding issues. We noticed no extra insulation had been put in on top of the block wall to tie in with the attic insulation.

 

Rockwool was put in on top of the wall.

 

His quote included the instalation of vents..he was waiting on clarification from our engineer as to number and location.

 

Now the installer says he will not install vents unless we pay alot more money As he he had planned on installing soffit  vents and cannot do that now because of the rockwool.

 

My thinking is that he never planned on putting in insulation along  the top of the wall to tie into the attic insulation. 

 

If we hadn't spotted it we would have been left with cold bridging the whole way around and completely defeated the point of running the EWI up beyond the soffit.

 

Our option now is tile vents and he has quoted thousands to put 8 in !!!  

 

How do we respond to this???
