How do you use windows and doors materials in a project?

So i found this material: https://substance3d.adobe.com/assets/allassets/d69c124a23418d8b5ad1e7091823f8023d853591?free=true

or this:

I understand that i can put them on my model. But what can i do next? I dont have same walls material as in this windows, so how can i make house look like it made from same stuff? I cant replicate same walls as used around this window, so they will stick out.
