Morphology

subflooring = subfloor (semi-transparent) = sub + floor + ing

The word is clearly built on 'subfloor', but the noun use of '-ing' in a building-material sense is somewhat specialized.

Etymology

Subflooring is simple: sub- means 'under', like in subway, and floor is the surface you walk on, so subflooring is the layer that sits 'under' the finished floor to support it.
