Installing Windows/Bi-Fold - Air Tight Help

[richo106]

Hi All

 

We are installing flush casement windows in our project. We went to try and get it as air tight as possible.

 

The window company are more than happy to use what I ask for when installing. 
 

I was thinking of putting the air tight tape on after installation (contega solido SL)

 

What can be put on during installation? Would it be worthwhile specifying which foam I want them to use? Any recommendations on that? 
 

Many Thanks
