Everything You Need To Know About A Thermally Broken Door


As the world becomes more focused on sustainability and energy efficiency, homeowners are searching for ways to reduce their energy consumption. One innovative solution that is gaining popularity is the thermally broken door.

This advanced technology can significantly improve the energy efficiency of your home, reducing heating and cooling costs, and enhancing comfort. But what is a thermally broken door, and why should you consider installing one in your home? Let's delve into the world of thermally broken doors and unveil the science behind this game-changing innovation.

What is a Thermally Broken Door?

The term "thermally broken" might initially sound negative, as though something is damaged. However, in the context of doors and windows, it refers to an engineering design that enhances energy efficiency.

A thermally broken door is one that is designed with a built-in thermal break - a non-conductive barrier within the frame that interrupts the path of heat transfer. This barrier, often made from reinforced and insulated polyamide, effectively "breaks" the thermal bridge, reducing the rate at which heat can travel through the door material.

Understanding Thermal Bridging

To fully appreciate the concept of a thermally broken door, it's crucial to comprehend what thermal bridging is. Thermal bridging occurs when heat flows across an object that has higher thermal conductivity than its surroundings, creating an easy path for heat transfer. Common materials such as iron, steel, aluminum, wood, and concrete can all act as thermal bridges, facilitating the transfer of heat from your cozy interior to the colder outdoors during winter, and vice versa during summer.

The Role of Thermal Breaks

Thermal breaks play a crucial role in minimizing energy loss through thermal bridging. These barriers are not completely impervious to heat; however, they pose a significant challenge for heat trying to cross them, much more than materials like wood or metal. When integrated into doors or windows, thermal breaks enhance their thermal performance, resulting in a more energy-efficient home.

The Making of a Thermally Broken Door

Manufacturing a thermally broken door involves the strategic placement of a thermal break within the door frame. The door is split into two sections, and a non-conductive material is inserted between them to create the thermal break. This ensures that the two metal parts of the door do not touch, thereby reducing heat conduction. Carbon is often used for this purpose due to its poor conductivity.

Why Choose a Thermally Broken Door?

Installing a thermally broken door comes with a host of benefits. Here are six compelling reasons why these doors are a top choice for modern homes:

Improved Energy Efficiency

A thermally broken door significantly reduces energy transfer, helping you maintain a comfortable temperature in your home throughout the year. This means you don't have to rely excessively on your heating or cooling system, resulting in lower energy bills and a smaller carbon footprint.

Enhanced Door Strength

Thermally broken doors are not just energy efficient; they're also remarkably strong. The addition of a thermal break increases the door's thickness, providing an extra level of protection and durability.

Increased Curb Appeal

Thermally broken doors are not only functional but also aesthetically pleasing. They come in a wide range of designs, allowing you to enhance your home's curb appeal without compromising on energy efficiency.

Protection Against Extreme Weather Conditions

Whether you're dealing with freezing winters or scorching summers, thermally broken doors can help maintain a comfortable indoor temperature. They effectively reduce heat loss during cold weather and prevent heat gain during hot periods.

Noise Reduction

The thickness of a thermally broken door also helps reduce noise transmission. Whether you live near a busy road or have a large, noisy household, these doors can help maintain a quieter, more peaceful home environment.

Prevention of Condensation

Thermally broken doors help maintain a more consistent temperature across the door surface, reducing the likelihood of condensation. This can prevent potential water damage and the growth of harmful mold around your door frames.

Installation of a Thermally Broken Door

While it's possible to install a thermally broken door as a DIY project, it's highly recommended to hire a professional. They will ensure that the door is correctly fitted and that the thermal break is functioning as intended.


Thermally broken doors are extremely valuable for homeowners due to their energy-saving abilities, which can significantly reduce utility bills. They offer the comfort of a more controlled indoor climate, blocking harsh outdoor elements while retaining warmth or coolness inside. With the sturdy structure, the durability and longevity of the doors they are a good investment, as maintenance costs are often reduced.

They are a pleasing visual quality that can increase the aesthetics of any home, thus potentially enhancing its overall market value. Given their remarkable thermal attributes coupled with their visual allure, it is undeniable that thermally broken doors are an innovative and future-ready approach to sustainable and cost-efficient home living.
