Take a look at your template / building materials.
Going from high (999) to low you want roughly a break up as:
- SEO operators
- structural concrete for slabs
- structural steel
- structural plywood
- structural wood
- roof finishes (tiles, thatched etc)
- structural concrete
- thermal insulation
- air gap
- non-structural concrete and bricks
- outer finishes (metal, plaster, wood panelling etc)
- PE foils and the like
- gypsum board finishes
- insulation for light separation structures (metal-stud walls and the like)
- inner finishes
- cement for floor finish
- earth / water / other terrain stuff
Following this principle (which is pretty much 99% how the standard template works, at least for the NL version), I can't say I have many problems with connections.
Basically you sometimes need two building materials for one type of product, for when it has a structural function and when it is of secondary importance to the load-bearing part of your model.
Insulation sometimes is tricky and may require some Complex Profile work (removing insulation where you can't get it done by automatic connection etc), but generally we can leave this until we get around to building permit documentation stage of a project.
Hope this helps a bit!
You might need to go over some of your composites to re-assign some building materials that should be more of a finish and less of a structural type.
