When assessing door designs, homeowners know a new door system is an investment in their home’s security, energy efficiency, and aesthetic appeal. If you’re new to the world of personalized door design, you might need to know what goes into a quality door system. This article will take a look at the anatomy of a quality door to help homeowners design the perfect door system, with the quality and functionality they need.

Why investing in a quality door is important

A quality door is your home’s first line of defence against external elements and potential intruders. A door also helps with energy efficiency, preventing air leaks and reducing heating and cooling costs. Also, a well-crafted door can enhance the curb appeal of your home, adding to its overall value.

The components of a quality door

Door slab

The door slab is the main component, usually made from durable materials like fibreglass, steel, or wood. These materials are weather resistant and extremely strong with a secure area for installing the lock, ensuring the door’s strength and security​​.

Centennial slabs are filled with a polyurethane foam that creates the core, similar to the insulating material in refrigerators. Not only does the foam improve the energy efficiency of your home, it provides strength and sound deadening.

Frame and jamb

The jamb is the transitional component between the entry system and your home. The frame or jamb is crucial for supporting the door’s weight and maintaining its shape. A well-installed frame ensures the opening is level, square, and plumb preventing warping and sagging. Frames can be made from various materials, like wood or composite, affecting the door’s overall strength and security​​​​.


Door hardware is more than just functional; it’s an integral part of a door’s character. Handles, knobs, and locks not only ensure security but also add to the door’s aesthetic appeal. 

High-quality materials like forged brass in hardware are essential. Unlike aluminium or plated steel, solid forged brass, like the materials used in Centennial hardware, is heavier and stronger. This durability enhances security and ensures smoother operation, adding to the door’s longevity and ease of use.


Hinges are the backbone of any door, and their durability is crucial. Centennial’s heavy-duty, ball-bearing hinges are a prime example of durability married with design. Made from solid brass, these hinges are resistant to daily wear and tear. 

Their robust construction is tailored to support the weight of heavy door systems, ensuring long-lasting functionality. The choice of solid brass for hinges isn’t only a testament to their strength but also to their ability to withstand frequent usage, making them an ideal choice for both aesthetic appeal and functional longevity.


Weatherstripping is a key feature for any door, serving as a barrier against insects, dust, and moisture. This not only protects your home but also significantly improves the door’s insulation, contributing to energy efficiency. 

Door lites and sidelites

Lites and side lites are decorative elements that transform a door into a source of natural light and visual appeal. These glass inserts come in various styles, allowing homeowners to customize their doors according to their personal taste and architectural style. 

Whether you choose full-length or partial lites and side lites, they bring a unique character to the door, blending functionality with design. They not only enhance the aesthetic of the door but allow more natural light into your home, creating a welcoming, illuminated entrance.
