Select the correct pair related to types of doors and their features.
-
A.
Collapsible door - Made of PVC panels
-
B.
Revolving door - Made of shutter slide on sides with help of runners and guided rails
-
C.
Battened and ledged door - Made of vertical bond and horizontal supports
-
D.
Flush door - Made of single wood plank
Correct Answer:
C. Battened and ledged door - Made of vertical bond and horizontal supports
Explanation:
The correct answer is C. Battened and ledged doors consist of vertical wood planks, known as battens, which are secured together by horizontal wooden members called ledges. This construction provides structural integrity and is a traditional method for creating sturdy, functional doors.
In contrast: - Collapsible doors are typically made of steel channels and flats, not PVC panels.
- Revolving doors consist of multiple wings rotating around a central vertical pivot, rather than sliding on tracks.
- Flush doors feature a completely smooth surface often made of plywood or veneer over a core, rather than a single solid wood plank.
