Door Frame

Jamb
The jamb is the main support system for the door and acts as the base for the door slab and side lights. The jamb is the ‘transition’ element of the door system that connects to your home. 

Sill
The sill is the threshold of the door – the part that we step on. The sill takes a lot of wear and tear.

 

 

Brick Mould
Brick mould is an exterior, matched trim piece that seals the frame and provides air tightness and beauty.

 

 

The Slab

What is most commonly referred to as the ‘door’, starts out as a slab. The slab is the main functioning part of the door system, the part that swings open and shut.

 

 

 

 

 

 

 

 

Centennial offers two slab material options.

1. Fibreglass Entry Door
2. Premium Steel Entry Door

Components of a slab

The slab is a critical component of a door system and like anything else, the 'whole' is only ever as good as the sum of its parts. It is vital that a premium door system start with a premium slab. When considering a door slab we must look at five key elements of the slab. 

Skin

The skin is the exterior of the door and this is the ‘fibreglass or ‘steel’ part of the slab. Depending on the material, the skin comes in smooth or ‘wood-grain’ textured finishes and comes in many different ‘panel’ configurations. Centennial skins can be coated with over 25 different colour options. 

Stiles and Rails 

• Stiles and rails are the internal ‘frame’ of the slab.
• Stiles are the sides (vertical) of the internal frame. 
• Rails are the top and bottom of the internal frame. 

Core

The core is the internal ‘fill’ of the slab and is a polyurethane foam injected into the slab that cures to a hard material, the same insulating material that you would find in refrigerators. The core provides insulation, strength, and sound proofing. 

Edge

The edge of a door slab wraps around stiles and rails to seal the slab and acts as a barrier to the core of the slab.

Lock block

The lock block is an added piece of material on the side of the slab where the handle set is attached. It provides added support for the handle and deadbolt and strength against attempted forced entry.

Hardware

Hinges
Hinges attach the door slab to the jam and allow the door to swing – open and close. Centennial only uses premium ball-bearing hinges ensuring easy and long lasting function.

 

Handle and Lock-set
The handle and lock-set are the tools that allow the door to open and close and securely lock the door system.

Handle and lock-sets can be a handle with a built-in or separate dead-bolt or a multipoint locking system that has three or more 'deadbolts' running the length of the door providing added security.

Peep hole 
A Peephole allows for external visual access to see who’s at your door without opening the door. Peepholes are optional.

 

Kick plate
Attached to the bottom of the exterior of the door, the kick plate protects the base of the door and provides a beautiful finished look to the door. Kick plates are optional.

 

 

 

 

 

 

 

 

Weather Stripping

Frame weather stripping
Attached to the frame this weather stripping seals the door to the jam when the door is closed.

Door sweep
Attached to the bottom of the slab, the sweep seals the bottom of the door when the door is closed but is flexible to allow the door to swing.

 

 

 

 

 

 

Lites

Door lite
Plain or decorative glass built into the door slab. 

 

Side lite
Plain or decorative glass built into the frame beside the door. A side light can be on either side of the door or both.

 

Transom
Plain or decorative glass built into the frame over the door.
