Everything you need to know about doors
Not sure what “rebate” or “jamb” means? No problem! In our glossary you’ll find simple, clear explanations of the technical terms most used in the world of internal and armoured doors.
Anchoring is the system by which the frame of an armoured door is fixed to the masonry, ensuring its stability and resistance against break-in attempts. A solid fixing is essential for the door's security and durability.
The architrave trim is the surround fitted around a door. It hides the point where the door frame meets the wall, for a neater, more finished look, and it also helps block out dust. Different materials are used, such as wood indoors or aluminium to withstand the outdoors.
Auxiliary bolts are security devices that add extra locking points to an armoured door, increasing its resistance to break-in attempts.
An unlocking system that recognises the user's unique features, such as fingerprints or face, for top security without keys. Ideal for anyone seeking convenience and advanced access control.
A biometric reader for armoured doors is a device that opens the door by recognising the user's fingerprint, face or iris, granting access to authorised people only. It does away with keys and offers a high level of security.
The deadbolt (or night latch bolt) is a mechanical security device that completely locks an armoured door from the inside, preventing it from being opened from the outside even with the key.
The moving part of the door that opens and closes. It can be made from different materials and open in various ways (hinged, sliding, folding, and so on).
The leaf of an armoured door is the panel that opens and closes: in practice, it is the physical, moving part that holds the lock, the internal reinforcements and is secured at the locking points. It is what people commonly call "the door" itself.
The door restrictor (also known as a safety hook, safety stop, deadbolt or latch) is a security device fitted to armoured doors, designed to limit how far the door can open to just a few centimetres and to let the owner deal with whoever is outside without compromising the safety of the home.
The door reveal lining (in Italian imbotte, also known as intradosso or passata) is the inner or outer perimeter surface of a door or window opening. In simple terms, the reveal lining is the section of wall that frames a door or a window, forming a visible surface that can have a different finish from the rest of the wall.
The draught excluder is the element that seals the gap between the bottom of the door and the floor, blocking draughts, dust and noise. On quality armoured doors it is an automatic blade built into the leaf, different from the perimeter door seals.
A flush armoured door is an entrance door where the leaf and architrave trims sit perfectly on the same plane, for a minimal, elegant look without giving up security.
Forced entry is the forced opening of a door or window achieved by breaking or forcing the locking system. It is a precise legal and technical term, different from break-in and theft.
The frame is the fixed steel structure of an armoured door, anchored to the wall, on which the leaf hinges and into which the bolts slide.
The hinge connects the door leaf to the frame and lets the door open and close. On an armoured door it must be sturdy, anti-lift and able to bear heavy weights without warping over time.
