Product Description

Hollow Shape PA66 GF25 Heat Insulation Strip for Aluminum System Windows and Curtain Wall
Product Introduction
Broken Bridge aluminum thermal break strip is an important criterion for distinguishing aluminum alloy doors and windows and broken bridge aluminum doors and windows.It is precisely because of the appearance of broken aluminum thermal break strips that the aluminum doors and windows of the broken bridge have good thermal insulation and sound insulation performance. The extruding high precision polyamide thermal break strip is used in windows and doors.Inserted in the thermal break aluminum profiles,it is the part of energy-saving window system for reducing heat sonduction.

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.

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.

 

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.
