Glossary

:
A

Active leaf

The door leaf of double-leaf door set that is usually opened first. It is fitted with the handle and the lock.

Architrave

When seen from the hinge side, this is the visible part of a doorframe when the door is closed.

B

Block frames

Block frame is the generic term for edge frames and butt frames.

Burglar-resistant doors

Burglar-resistant doors are used in residential or office buildings for instance. The door leaves of these door sets have a special structure, and the door and frame are fitted with special fittings. The fittings features are determined by the resistance class and are decisive for the time the door can prevent an attempt of violent intrusion.

Butt frames

The butt frame is a type of block frame that it mounted inside the wall opening. It is mainly used when there is no wall connection, e.g. not enough place on the wall for the architrave of a wooden lining frame. 

C

Climate classes

Doors are recommended for various temperature categories. The different requirements are described in three climate classes. The selection of the appropriate climate class prevents warping in the event of strong temperature variations on either side of the door. The climate class is of particular importance for apartment entrance doors.

Controlling dimension

The controlling dimension is as special dimensional unit in the field of construction that is always referenced to a multiple of an eighth of a meter (12.5 cm). The controlling dimension forms the basis of all dimensions in building construction, including the door sizes.

Counter-rebate

This is a special type of door leaf edge at the fixed wing of double-leaf door sets. It interlocks with the rebate of the active leaf when both leaves are closed.

Cylinder (profile cylinder for a profile-cylinder lock)

It is a part of a door lock and ensures the reliable and secure locking up of a door set. The length and size of the profile cylinder to be ordered depend on the thickness of the door leaf and its rebate. For reasons of security, the cylinder is not included in the scope of delivery by Westag & Getalit and only installed on site.

D

Decors

Decors are either true-to-nature wood reproductions or plain coloured and are made of PVC foil.

DIN direction

According to the DIN standard, a door closes to the right when the hinges are on the right and the handle on the left side of the door leaf. Accordingly, a door closes to the left when the hinges are on the left and the handle on the right side of the door leaf. To assess the closing direction of the door, you must be on the side where you can see the full door leaf and not the doorframe.

Door leaf

The door leaf is often simply called a door and consists of the moving part of a door set that can be opened and closed.

Door leaf structure

The door leaf structure describes the various components of a door leaf, such as the surface, the core, etc.

Door set

A door set consists of the door leaf and the doorframe.

Doorframe

The doorframe is the structure that lines the wall opening and to which the door leaf is hinged. It is also called wall surround or jamb.

E

Edge design

The edge design describes the shape of the edges of a door leaf. There are two versions: rectangular and round edges.

Edge frames

An edge frame is a type of block frame for special applications and is always mounted in front of the wall. It is used for slender walls with low thicknesses or special wall connections.

F

Fanlight

The fanlight is the glass part of a storey-high door or draught excluder element above the door leaf.

Fire-rated doors

Fire-rated doors are able to resist to a fire for a particular period (30 minutes for instance) and must be self-closing. In addition to fire-rated doors, we also offer combined versions, e.g. for additional smoke protection requirements, or pure smoke protection doors that prevent the penetration of smoke into the room.

Fittings

Functional components of a door set such as the hinges, lock or handle.

Fixed wing

Also called fixed leaf, is the door leaf of a double-leaf door set that is always opened second. Under normal conditions, it is kept closed most of the time.

Floor sealing

Floor sealing is a seal that is installed in the bottom of the door leaf and lowers automatically when the door is closed. It is important for the sound proofing characteristics of the door. The advantage of the floor sealing in comparison to a threshold is that it does not involve any risk of stumbling and is no obstacle to wheelchairs.

Forend

The forend is the metal plate around the deadlock and the latch that you can see when the door is open.

Functional doors

Functional doors are fitted with special features to improve their properties. Due to special door leaf structures and particular fittings, they provide better protection against noise, smoke, fire, intrusion, moisture or temperature variations, for instance. Functional doors can also enhance your private living area with useful functionality.

G

Glass opening

The glass opening is a cut-out in the door leaf filled with glass. Glass openings are the ideal solution to bring daylight into rooms without windows.

Glassbar frames

A frame of beads applied to the glass opening of a door that subdivides the glass surface into smaller sections.

Glassbead

Glassbeads are used to fix the glazing of a glass opening. They are typically foil-wrapped either in decor or veneer reproduction.

H

Handle

The handle is a fitting device that is used to open and close a door by hand. Handles are available in many shapes and materials and contribute considerably to the overall impression of a door. In general, they are not included in the scope of delivery of a door leaf by the manufacturer.

Hinge

The hinge of a door set is the pivotal connection between the door leaf and the frame. Hinges consist of two parts: the door part and the frame part. The frame part is fixed to the frame inside the hinge cage, the door part into the door leaf.

Hollow chipboard

Hollow chipboard is chipboard with tubular channels running through it. It is used as core material for interior doors in residential buildings that are exposed to high stress and strain.

Honeycomb core

Also known as special honeycomb core or composite core. This cardboard core is suitable for simple door leaf structures. Honeycomb cores provide sufficient stability for interior doors. A special manufacturing process prevents corrugation of the surface of door leaves with honeycomb cores.

J

Jamb

Jamb is another term for frame.

Jamb plate

The jamb plate connects the rebated and profiled architrave of a doorframe; the jamb plate varies depending on the wall-thickness to ensure the doorframe can be mounted optimally.

L

Laminated safety glass (LSG)

A foil layer is glued between two large glass panes in the production of this type of glass. When the pane is hit, it only cracks but does not break. Laminated safety glass provides even greater safety than tempered safety glass.

Latch

The latch is the part of the lock that locks the door when you turn the key.

Lock

It is a fitting used to lock a door set. There are three types of locks: The traditional single tumbler lock (key with bit) that is only used for interior doors, the useful WC lock that can also be opened from the outside in the event of an emergency, and the profile cylinder lock (profiled security keys) suitable for apartment entrance doors. The profile cylinder itself is not included in our scope of delivery.

Lockbolt

The lockbolt is part of the locking mechanism of a door. It is activated via the handle and keeps the door closed.

Locking plate

The locking plate is a metal plate fixed to the frame at the height of the lock and fitted with the corresponding openings to accommodate the latch and the lockbolt.

P

Panels

The panels are the filling elements of a door leaf between the glassbars or in panel framings. Panels are typically made of wood or glass and produce a striking look. Panel framings are profiled bead frames around the panels in the door leaf.

Passageway frame

Lining of a passage between rooms. It is not fitted with a door leaf and can also be used in combination with a sliding door. Passageway frames do not have sealings or fittings.

Plant-on beading

The term refers to profiled beads that are attached to the door leaf surface and increase the value of the door. They are used to transform plain doors into Country House doors.

Plinth

The plinth is the area of the door from the lower door edge to the glass opening, or to the panel.

Profiled architrave

The profiled architrave is the counterpart to the architrave on the other side of the wall and covers the gap between the jamb plate and the wall.

R

Rail

The rail/stile is the horizontal or vertical part of a door leaf between the outer edge and the glass opening or panel. There are specific rail/stile widths that doors must have to ensure the door leaf cannot be damaged. The area from the lower edge of the door to the glass opening or the panel is often not called a rail/stile but rather a plinth.

Real wood veneer

This is a type of surface that is made of real wood and finished with a lacquer coat. Westag & Getalit WestaLife doors feature this kind of surface.

Rebate

The door leaf of rebated doors sits on the outer surface of the frame whereas the door leaf of unrebated doors, which are also called flush-closing doors, sits completely inside the frame when the door is closed. The entire door has a flush surface. In Germany, the rebated door set is the most common type of interior door. It is easier to mount and offers higher functionality in some cases.

S

Single-point locking

Single-point locking is the typical locking mode of standard doors. The locking point is above the actual door lock and locking plate. For apartment entrance doors, mainly three-point locking systems are used.

Size to be ordered

Door leaf width, door leaf height and wall thickness are the decisive dimensions when ordering door sets. The dimensions of the door are referenced to the controlling dimensions in this regard. The overall door leaf size results from the incremental dimensions. The goal is to order standard sizes wherever possible. Wooden lining frames are suitable for almost every wall size due to their adjustment range.

Sliding door set

A distinction is drawn between sliding doors running into the wall and those running in front of it. Sliding doors could be single- or double-leafed. They are displaced parallel to the wall when you open them.

Solid chipboard

Solid chipboard is an important material for the construction of doors and frames. The continuous chipboard is a suitable core for doors exposed to high stress and strain which means that it is also used for fire-rated or soundproof doors.

Soundproof doors

Soundproof doors prevent the propagation of sound due to a special structure of the door leaf and the addition of a floor sealing.

Surfaces

Westag & Getalit offer doors and doorframes in four different surface versions: highly wear-resistant PVC foils (PortaLit and GetaLit), inexpensive decor foils (DekoRit), and elegant lacquer finishes (WestaLack).

T

Tempered safety glass (TSG)

A pretension is built up inside the glass in a special process that ensures fine shattering during breakage. The very small size of the splinters help to minimize the risk of injury and prevent serious cuts. Westag & Getalit offer various types of safety glass.

Top panel

The surface of a storey-high element between the door leaf and the ceiling.

Transom

A distinction is made between vertical and horizontal transoms. Transoms of double-leaf doors or draught excluder elements are the structural connection between the door and the fixed side panel and or a fan light.
