What is a thermal break strip?
Thermal break is a reinforced polyamide strip (a non metallic, composite, structural, material) fixed between the inside and outside profiles, creating an insulated barrier within the window frame.
Over the years, polyamide heat-insulation strip has been widely used in glass curtain walls due to its good properties and low cost.
Especially polyamide 66 reinforced by 25% glass fiber thermal break strips, they are inserted into aluminum window, door and facade profile for thermal insulation.
Thermal break strip, also called heat insulation strip, is a part of aluminum bridge profile. The heat-insulating bridge aluminum-plastic profile can realize the three-way sealing structure of doors and windows, and reasonably separate the water vapor chamber. It successfully realizes the pressure equalization of gas and water, and significantly improves the watertightness and airtightness of the doors and windows.
The Function of Thermal Break Windows
1. Broken bridge aluminum thermal break strips reduce heat conduction: the heat broken bridge aluminum alloy profiles are adopted, and the hollow glass structure is adopted. The broken bridge aluminum doors and windows reduce the heat conduction through the doors and windows. In this way, it will not feel hot under the high temperature of the scorching sun in summer. It's cold and windy in winter, and we don't feel cold. This ensures that the indoor temperature is maintained.
2. Prevent condensation: The temperature of the inner surface of the broken bridge aluminum door and window profile with thermal break strips is close to the indoor temperature, reducing the possibility of indoor moisture condensing on the surface of the profile due to supersaturation. This is crucial for the insulation of the window.
3. The broken bridge aluminum thermal break strip plays the role of heat preservation and energy saving. Broken bridge aluminum door and window frames with thermal insulation strips can reduce the heat loss through the window frames by one-third. In summer, if there is an air conditioner, window frames with thermal insulation strips can reduce energy loss more.
4. To protect the environment: through the application of the thermal insulation system of broken bridge aluminum doors and windows, energy consumption can be reduced, and the environmental radiation caused by air conditioning and heating can be reduced at the same time.
5. Broken bridge aluminum thermal break strips are good for health: the heat exchange between the human body and the environment depends on the indoor air temperature, air flow speed and outdoor air temperature. By adjusting the indoor temperature of broken bridge aluminum doors and windows, the use is lower than 12~13 ℃, and the most comfortable environment has been achieved.
6. Broken bridge aluminum thermal break strips reduce noise: the use of hollow glass structures with different thicknesses and heat-insulated bridge-broken aluminum profile cavity structures can effectively reduce the resonance effect of sound waves, organize sound transmission, and reduce noise by more than 30dB.
Advantages of using polyamide strips:
They provide a better thermal insulation.
They need lesser use of metals.
The polyamide strips are cost-effective.
They are easy to create with thermal barriers.
They help in resources to be conservedand can reduce operating costs.
They ensure maximum stability of the structure.
They are more than effective in resisting condensation.
They don’t require any special handling or fabrication.
Application
Polyamide strip is one of the most common materials used for years to create thermal breaks in curtain walls, commercial windows, doors, and more. It is installed between the interior and exterior profiles of the windows that forms an insulating barrier between the two.
Characteristic of PA strips
According to different storage time and ambient climate, the dimension of PA strips will increase slightly because of the natural moisture absorption. And the mechanical properties will change slightly too.
So, PA strips should be transported and stored under dry conditions away from the influence of weather. (rain, direct sunlight etc.)
PA strips storage and handling:
Because PA66 is a hydrophilic substance, it will absorb the surrounding water. The rate and amount of water absorption depend on the ambient temperature, ambient humidity and storage period.
The relative humidity is higher in summer than in other short-term storage seasons. High moisture content (more than 2%) will affect the quality of wear-resistant strips.
When the insulation single bundle is removed from the shelf, it may be deformed. If it is not straightened in time, it will cause permanent deformation.
Therefore, it is recommended to keep it horizontal in a ventilated and dry environment, pay attention to waterproof, stay away from heat source, avoid stress and minimize bending.

Different shapes:
I-type thermal break strip is a common insulation material for doors and windows, with a shape similar to the uppercase English letter "I". It is the first generation and easiest shape of polyamide strips.
Compared to other types of thermal break strips, the advantage of I-type strips is that their longer length can better adapt to the width of doors and windows, improving the thermal break effect.
In addition, Type I insulation strips can also adapt to different door and window sizes and specifications through their own shape and structure, with high flexibility and adaptability.
For the I-type strips, we can provide the following size or customize according to customer’s drawing.
The C-type design provides a longer heat conduction path, resulting in better heat insulation performance than I-type strip, while also having better longitudinal load-bearing capacity. Besides, the C-type PA strip is also a necessary condition for the stepped drainage of thermal broken bridge aluminum.
For the C-type strip, we can provide the following size or customize according to customer's drawing.
The design of T-type thermal break strips usually includes a horizontal section and a vertical section, forming a "T" - shaped structure.
This design adds a small section under the thermal break strip, allowing the sealing strip to overlap with the thermal break strips, thereby improving the overall insulation performance.
For the T-type strip, we can provide the following size or customize according to customer's drawing.
Hollow thermal break strip, also known as multi-cavity insulation strip, can reduce heat transfer by changing the air flow path, thereby achieving insulation effect and further improving insulation performance.
Hollow thermal break strip are currently the mainstream products in the market and can support large width sizes. Many thermal break strips with a diameter of 35mm or more on the market are made into multi-cavity shapes, and their longitudinal load-bearing capacity is very high.
For the hollow type strip, we can provide the following size or customize according to customer's drawing.
