Nylon PA66 Thermal Barrier Strip for Noise Insulated Window System as Decoration Material
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.
What is a Thermal Barrier?
Thermal barriers are made from resins that create a "thermal break" between the inner and outer surfaces of aluminum fenestration.
Thermal barriers reduce heat loss or heat gain through the aluminum.
Thermal barriers improve the U-value characteristics of finished systems.
Thermal barriers are about energy conservation, U-values and government codes
70 percent of aluminum fenestration systems produced in North America contain a thermal break
Primarily used in colder climates to reduce heat loss
Increasing use of thermal barriers to reduce heat gain and also reduce heat loss
Developers, architects and designers are demanding better performance in terms of power usage
Stricter government regulations to reduce power usage in buildings to combat environmental concerns
Aluminum, if it is to retain its market superiority in terms of its structural integrity, will have to achieve better performance in terms of U-values
The use of thermal barriers will assist manufacturers to achieve improved LEED performance.

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.
Storage Conditions
The strips will be stored in the ventilated and dry environment, horizontally placed, paying attention to waterproof, keeping away from the heat source, avoiding heavy pressure and the contact with acid, alkali as well as organic solvent.
Delivery
We have the production capacity of 100000 meters per day. For common specifications, we have molds, and will be shipped in 7-15 working days after receiving the deposit.
Packages
For all specifications/shapes, they could be packaged in linear, the length will be 6 meters, or customized.
For the Shape "I", "C", and some simple shapes, they can be packed in rolls. 400-600 meters/roll.
