Polyamide Thermal Break Strips for Aluminun Windows
Nylon66 Thermal barrier strip of polyamide extruding product, which is widely used for bridge insulating aluminum profile, has excellent performance such as high temperature resistance, chemical resistance, ultraviolet resistance and water resistance. The Linear Expansion Coefficient of the product is close to that of aluminum profile, which makes long durance of spacer and aluminum profile. The product has been tested by the Material Test Center of SGS. The product meets the National Standard of GB/T23615.1-2009.
Shape I, shape C, shape T, shape CT and shape HK is the most common shape, we can also according to customer requirements or drawings to customize other special shape.
Is a thermal break good?
Adding a thermal break to a window or door prevents both heat and cold from transferring through the frames altogether, alleviating issues that might be caused by extreme environments. By controlling this transfer, thermally broken windows and doors improve energy efficiency.
What is the best thermal break?
As an energy-saving, polyamide thermal break profile is the best thermal break material for aluminum profiles connections. Boasting high compressive strength, polyamide thermal break profile is a premier thermal bridging solution that won't compromise a structure's integrity.

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.
Polyamide is a plastic that insulates more than 500 times better than aluminium, so thermal break profiles have a much lower Uf value - and transmit much less heat or cold. As a result, your home stays warmer in winter, while keeping the heat outside more easily in summer.
Expertise in the production of standard polyamide thermal break strips.
Respect customers' needs, provide customized products, try best to satisfy customers' requirements.
Fast service and on-time delivery
Strict quality control system, each production process will be strictly supervised by us.
We can provide all products on the insulation strip production line and the technical support.
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.)
Please feel free to contact us if you have any questions.
