TL;DR
Vinyl siding is extruded PVC cladding for exterior walls, the most common siding in American housing because it never needs paint, shrugs off insects and rot, and installs quickly over a drainable housewrap. Quality is graded largely by thickness, from builder-grade .040 inch to premium .046 and up, with ASTM D3679 as the governing material standard.
What it means
Vinyl siding is extruded PVC cladding for exterior walls, the most common siding in American housing because it never needs paint, shrugs off insects and rot, and installs quickly over a drainable housewrap. Quality is graded largely by thickness, from builder-grade .040 inch to premium .046 and up, with ASTM D3679 as the governing material standard. Its defining quirk is movement: panels expand and contract enough that they hang loosely on nails through slotted hems, and face-nailed or tight-locked installations buckle in the first hot season.
