Customizable Thermal Barrier Tape For Insulated Broken Bridge Aluminum Window Frames

What is Polyamide Thermal Barrier Strips?

1. Pre-extruded profiles made from polyamide with 25 percent glass-fiber

2. Locked in place in ‘pockets’ extruded into two separate (inner and outer) aluminum extrusions

3. Enables finished assemblies with different finishes and colors on each surface

4. Aluminum extrusion pockets need to be ‘knurled’ prior to insertion of the polyamide profiles-and ‘rolled’ to create a structurally-secure finished assembly

5. The polyamide profiles can be supplied with ‘sealing-wire’ which give a reliable seal and enhanced shear strength when activated by heat e.g.-powder coating

6. The aluminum extrusions can be finished either before or after installation of the polyamide strips

What are the different types of thermal barriers?

Currently, there are two principal types of thermal barriers: polyamide thermal barrier strip and pour & debridge (P&D).

Our company only produce polyamide thermal barrier strip.

Polyamide is a plastic that insulates more than 500 times better than aluminum, so thermal break profiles have a much lower Uf value – and transmit much less heat or cold. As a result, a building stays warmer in winter while keeping the heat outside more easily in summer.

Why do you need a thermal break?

Why are thermal breaks important? Thermal breaks are essential for any external modern glazing system. Thermal bridging can be responsible for up to 30% of a property's heat loss. This lowers the homes energy efficiency, leading to higher heating bills.

Application and Advantages

Aluminium window has the disadvantage of limited thermal insulation. Its Uf value, which indicates the amount of heat that passes through a window profile, is simply too high. If your windows have standard aluminium profiles, your home may develop condensation, or even mould. Besides the resulting high repair costs, household mould also aggravates respiratory problems such as asthma.

But that disadvantage has now been completely eliminated if you install polyamide strips in aluminum windows. In fact, thanks to the development of a new invention known as thermal break profiles, aluminium is at least as good as its competitors. In these profiles, produced with specialized machines, a polyamide strip is placed between the inner and outer sections of the profile.

Storage:

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.

If you have any specific questions, please contact us and we are happy to provide you with relevant services.

We have been making research and development for special material of PA66GF25 thermal break strip since 2006, we have a deep understanding and rich experience of the relevant industry. We can provide our clients with special material of PA66GF25 thermal break strips of all levels. During these years, we also established a good partnership with many companies is the upstream and downstream industry.

In 2016, we together with factory of mold, extruder and factory of thermal break strips established Zhangjiagang Bangyu Engineering Plastics Co.,Ltd, which is responsible for international import and export business. In 2021, Zhangjiagang Bangyu Engineering Plastics Co.,Ltd was changed ans registered as Suzhou Polywell Engineering Plastics Co.,Ltd. 
The reason why we joined Polywell together with the other two companies is that in this field, the requirements for professionalism are very high. In this field, the company that produce raw materials usually do not research machines and molds, but clients usually need all of them. We found this point, so we joined two other companies established Polywell company together. Polywell can provide a whole set of solution about thermal break strips, including raw material –PA66GF25 granules, extruders, molds, and technical support. This is our biggest advantage.

Strive for customers’ satisfaction and success, service to customers is the principle we’ve always been insisting in the last ten years, to provide our customers with high-quality products and service.

Our domestic sales volume is very stable. We are the main supplier of two listed companies which produce aluminum profile at home, and will obtain the long-term cooperation with them. Otherwise, we also have the long-term cooperation with many small manufactures.

If customers have the need of purchasing other products, we can also provide procurement service.
