Which type of door consists of vertical members called stiles and horizontal members called rails?

The type of door that consists of vertical members called stiles and horizontal members called rails is a panel door. This design includes a frame with panels set within it, often allowing for a variety of materials and textures. The stiles are the vertical parts that form the sides of the door, while the rails are the horizontal parts that form the top and bottom. This construction method provides strength and stability, as well as aesthetic appeal, allowing for decorative paneling or designs to be incorporated into the door.

In contrast, solid core doors, flush doors, and hollow core doors do not feature this traditional construction with stiles and rails. Solid core doors have a solid interior for sound insulation and security but do not necessarily incorporate the distinct frame-and-panel design. Flush doors have a flat surface without the frames for panels, presenting a minimalist design. Hollow core doors are typically lightweight and have a hollow interior, intended for interior applications and also lack stiles and rails. This distinction in construction methods highlights why the panel door is unique in its design features.
