What are Thermally Broken Windows, and Why do you need them?

By Ramarex

A study in 2018 revealed, “Around 318,891 homes are affected by dampness and have approx. 252,855 houses have visible mold.”

Molds and dampness are correlated with asthma, allergies, skin rashes, and severe respiratory tract diseases. Therefore, to cater to this, a viable solution in the form of thermally broken windows was introduced. 

In this article, we will discuss everything about thermally broken windows and how it benefits you in the long run.

What is Thermally Broken Windows?

If you want to improve the energy efficiency of your windows and prevent heat transfer through their frame, you need thermally broken windows.

That’s because thermally broken windows incorporate a “thermal break” in the frame, creating a barrier to reduce heat transfer. The insulated barrier is usually made of reinforced polyamide—a type of plastic with a low thermal conductivity that prevents the heat from entering inside or leaving the house. 

However, in premium quality windows, this insulated material is made of aluminum, which is more powerful and durable than polyamides to maintain a comfortable temperature within the house.

Fun fact: In Australia, around 90% of the windows installed are Aluminum.

In short, thermally broken windows are high-performance insulated windows against heat and cold induction through a feature termed “thermal break”.

What are the types of thermal breaks?

It might surprise you but there are different methods to achieve the thermal breaks in your windows.

Polyamide strips:

Polyamide has low thermal conductivity since it’s a non-metallic material. It is mainly used in Aluminium window frames where it is inserted in between the outer and inner parts of the frame to prevent heat transfer.

Insulating foam:

To create an insulating layer that prevents heat transfer, insulating foam is usually injected between the window frame sections. The foam expands and hardens to create a thermal barrier, and ultimately reduces heat transfer.

Thermal inserts:

Many materials, including fiberglass or reinforced polyamide, are used as thermal inserts. They are placed within the window frame and create a thermal bridge that increases energy efficiency in the long run.

All the three types of thermal breaks are beneficial and suitable for specific window frames, materials, and designs. Your window manufacturer will guide you about what’s best for you.

Why should you install thermally broken windows in your home?

There are major advantages of thermally broken windows and that’s the real cause of their immense popularity. Some of the advantages of thermally broken windows are stated below:

Exceptional thermal performance

As mentioned earlier, these windows incorporate a thermal break in their frame that reduces heat transfer. It also allows you to maintain a pleasant temperature, regardless of extreme weather conditions.

In winter, your windows will keep the heat inside, and in summer, they will keep the heat out of your house, maintaining a comfortable indoor temperature without using considerable energy.  

Fun fact: Thermally broken windows are warmer in winter and cooler in summer. No more insane power bills for heating or cooling your home! 

Reduced condensation

Condensation occurs when warm, humid air trapped inside your house comes in close contact with a window surface. This allows moisture to form water droplets through the process called condensation.

Condensation is a nightmare to deal with considering it’s the root cause of dampness and mold, ultimately severe health problems.

However, thermally broken windows, in combination with proper heating and ventilation result in reduced condensation and keep your home nice, warm, and dry all around.

Happy, healthy homes

A healthy home is a happy home with no traces of moisture, mold, pollution, and noise. However, a study in 2018 revealed that 318,891 homes are affected by dampness and. 252,855 houses have visible mold.

The numbers are huge!

And so are the health risks, including asthma, allergies, skin rashes, and other respiratory issues.

Therefore, to mitigate these concerns, the use of thermally broken windows is recommended in order to live a stress-free, healthy life with no signs of moisture and mold that affect your physical and mental health.

Increased property value

Your home is your asset. Therefore, you should always invest in it wisely. Nowadays, with the increasing popularity of eco-friendly homes, the demand for thermally broken windows has considerably increased.

Buyers are looking for properties that are energy-efficient to minimize their living costs and maximize their living standards in terms of comfort, durability, and quality. 

Noise reduction (Soundproofing)

If you live on a busy street, the need for privacy and serenity becomes paramount.

To achieve a level of comfort in busy areas amid the hustle and bustle, homeowners always appreciate the soundproof windows that cancel out the outside noise of traffic, pets, or just general noise.

Luckily, the thermal break in your thermally broken windows provides amazing soundproofing that separates your inside from the outside world effectively.  

Bigger savings 

Sure, the installation of thermally broken windows might pose a serious challenge to your budget. But, over time, your low utility bills will outweigh the total cost of installation.

That’s because when you install thermally broken windows, you use minimum energy to heat or cool your home, resulting in reduced power bills.

Versatility

Since we have around a thousand different styles of windows in Australia, you might wonder if thermally broken windows are limited in operational styles.

The answer is a plain NO!

Surprisingly, thermally broken windows are easily found in all of the operational styles, and finding a manufacturer that creates your favorite style in these windows should never be a problem.

You can get thermally broken windows in various styles, including single and double-hung windows, sliding windows, picture windows, casement windows, and much more—you name it.

Also, you can request customized windows in shapes or patterns from certain manufacturers at an additional cost.

Thermally broken windows vs. Double Glazing—Which is better?  

Now, to answer the most interesting question: What should I go for? Double glazed windows or Thermally broken windows?

Because over many years, homeowners have been using double glazed windows to keep their buildings, homes, and even offices comfortable in extreme weather.

Double glazing works by interrupting the transfer of heat through condensation—A layer of air (particularly, argon gas) is added between the two glass panes that are separated by non-conductors.  

However common and popular, the efficiency of double glazed windows is compromised because of its window frames.

For example, on a cold winter night, feel the inside of your aluminum joinery of your double glazed windows. You’ll realize that the inside is just as chilly as the outside.

That’s because the window frames are not targeted for the thermal break technique. And just like glass, the window frames (mainly Aluminium) are great conductors of heat or cold.

Therefore, the performance of double glazing is not as outstanding as the thermally broken windows where heat transfer through the entire window is reduced by separating the inside and outside of the window via a poor conductor.  

So, if you’re living in Australia, installing thermally broken windows for your home, buildings, or offices is highly recommended. Since Australia can get really hot in summer and cold in winter, you will appreciate the comfortable internal temperature while reducing your energy bills.

For professional assistance, it’s always best to consult a window specialist in your local area in Australia.
