cull outside faces

so after seeing the new 3d voronoi component (very awesome btw! thank you!) i wanted to recreate a manual 3d voronoi project i did. for the last part im looking for the easiest way to cull out all the faces which lie on the outside of the structure.

im using the 3d voronoi with a regular bounding box so there is no funky shape, eventually there could be, but i would like a way to cull out and group all the outside faces in order to apply my louver script. i tried using the inclusion component and decomposing the areas of each face but got hung up. any suggestions?

hey thanks the solution worked great. however is there a way i can cull out these outside faces but keep the same tree structure? i had to do some run-a-rounds, but basically i want to take the outside faces, cull and remove the ones which are less than a specific area, and the remaining ones then are divided and have a simple louver system added. as an alternative to apply a louver system i was also looking at a way to take the louver lines, extend them to the border of the brep face and use the splitface component. i attached the grasshopper file (needs 8.0.63) and some screen shots of how I was looking to do it.
