Door Operation and Wood Door Types

Flashcards covering various door operations, wood flush door cores and grades, wood rail-and-stile door anatomy, and batten doors.

Swinging Door

A door that turns on hinges about a side jamb or pivots from a head jamb and threshold, serving as the most effective door type for thermal/acoustic insulation and weather resistance.

Bypass Sliding Door

A door system where doors slide on an overhead track and floor guides, offering access through only $50\%$ of the doorway width.

Surface Sliding Door

A door surface-hung on an exposed overhead track that provides access through the full width of the doorway without requiring operating space.

Pocket Sliding Door

An interior door that slides on an overhead track into and out of a recess within the width of a wall.

Bifold Doors

Doors with hinged panels that fold flat against one another, dividing into two parts and used primarily as a visual screen to enclose closet and storage spaces.

Accordion Doors

Multileafed interior doors hung from an overhead track that open by folding back in the manner of an accordion to subdivide interior spaces.

Hollow Core Doors

Lightweight doors constructed of a framework of stiles and rails encasing an expanded honeycomb core or grid of wood strips, intended primarily for interior use.

Solid Core Doors

Doors featuring a core of bonded lumber blocks, particleboard, or mineral composition, used primarily as exterior doors or where increased fire resistance and sound insulation are desired.

Bonded Lumber Core

The core type in solid core flush wood doors that is the most economical and widely used.

Mineral Composition Core

The lightest solid core material, which provides fire resistance but possesses low screw-holding strength and makes cutouts difficult.

Premium Grade Veneers

Hardwood veneers suitable for natural, transparent finishes.

Good Grade Veneers

Hardwood veneers suitable for transparent or paint finishes.

Sound Grade Veneers

Hardwood veneers suitable for paint finishes only, requiring two coats to cover surface defects.

B-label Doors

Fire-rated doors that have a $1\text{ hour}$ or $1\frac{1}{2}\text{ hour}$ UL-approved rating.

C-label Doors

Fire-rated doors that have a $\frac{3}{4}\text{ hour}$ UL-approved rating.

Sound-Insulating Doors

Special doors featuring faces separated by a void or damping compound, requiring special stops, gaskets, and thresholds.

Wood Rail-and-Stile Doors

Doors consisting of a framework of vertical stiles and horizontal rails that hold solid wood or plywood panels, glass lights, or louvers in place.

Hinge Stile

The vertical stile from which a rail-and-stile door is hung.

Lock Stile

The vertical stile of a rail-and-stile door that receives the lockset.

Lock Rail

The horizontal rail of a door that meets the shutting stile at the level of the lockset.

Batten Doors

Site-fabricated doors consisting of vertical board sheathing nailed at right angles to cross strips (ledgers) with diagonal bracing, used primarily for economy in rough construction.
