The term “thermally broken” might sound like a defect or a malfunction to some, but in the world of window frames, it represents a significant advancement in technology. Thermally broken window frames are specially designed to improve insulation and reduce heat transfer, playing a critical role in energy efficiency. This blog post aims to answer your most frequent questions about thermally broken window frames and guide you in making an informed decision for your home or office.

In simplest terms, a “thermal break” is an element of low thermal conductivity placed in an assembly to reduce or prevent the flow of thermal energy between conductive materials. In the context of window frames, a thermal break is typically a strip of insulating material placed between the inside and outside of the window frame to prevent heat or cold transfer, effectively breaking the thermal path.

Thermally broken window frames offer several benefits. They significantly reduce the amount of heat that can be transferred through the frame, leading to better insulation and energy efficiency. This can result in substantial savings on energy bills, especially in climates with extreme temperatures. Additionally, they can prevent condensation, which can lead to mold and mildew, and they can also reduce external noise.

Thermally broken window frames can be constructed from a variety of materials. The most common are aluminum, PVC, and wood. Aluminum, while being strong and durable, is a good conductor of heat. Therefore, a thermal break is essential to improve its insulating properties. PVC and wood naturally have better insulating properties and don’t always require a thermal break, but it can still be added for superior performance.

Making a thermally broken window frame involves placing an insulating barrier between the interior and exterior sections of the frame. In aluminum frames, this is typically achieved by splitting the frame into two separate pieces and then linking them with a highly insulating plastic connector. The frames are then mechanically crimped together, creating a single, sturdy frame with a built-in thermal break.

The primary difference between thermally broken and non-thermally broken window frames is their thermal performance. Non-thermally broken frames allow more heat transfer, leading to higher energy costs and less comfort inside the building. On the other hand, thermally broken frames significantly reduce heat transfer, providing better insulation, improved energy efficiency, and increased comfort.

Thermally broken window frames tend to be more expensive than their non-thermally broken counterparts due to the additional materials and processes involved in their manufacture. However, the increased cost is often offset by the long-term savings on energy bills. Moreover, they can also add value to your property due to their superior performance and durability.

Thermally broken window frames are not only energy-efficient but also durable and require minimal maintenance. They are resistant to weathering, corrosion, and fading. With proper care, they can last for many years, making them a cost-effective choice in the long run. Regular cleaning with a non-abrasive cleaner and soft cloth is usually enough to keep them in good condition.

Before deciding whether thermally broken window frames are worth the investment, it’s important to consider your specific needs and circumstances. If you live in an area with extreme temperatures or if energy efficiency is a top priority for you, then they are certainly worth considering. Despite the higher initial costs, the long-term savings on energy bills and the improved comfort can make this investment worthwhile.

Thermally broken window frames represent a significant step forward in window technology. By breaking the thermal path, these frames can greatly improve the energy efficiency of your home or office, saving you money and making your space more comfortable. As we continue to strive for more energy-efficient and sustainable ways of living, understanding and implementing technologies like thermally broken window frames are becoming increasingly important. As always, it’s essential to weigh the benefits against the costs and consider your specific needs before making a decision.
