Nylon Polyamide Strip Heat Insulation Good Quality Used for Sliding Aluminum System Window and Door

What is a heat insulation strip?

Insulation of aluminum doors and windows sealed with insulation strip is the one with the glass fiber reinforced polyamide nylon (PA66), referred to as Nylon 66 insulation strips, expansion coefficient is small, heat-resistant, and anti-aging properties.

High Precision For Aluminum Sash Window Frame PA66 25% Fiberglass Thermal Insulation barrier strips.

Inserted in the thermal break aluminium profiles, and being the part of energy-saving window system for reducing heat conduction.

The shape I polyamide thermal barrier material can prevent the window frame from dust and water and could realize a better Uf value by sealing with a rubber profile, mostly used on the sash.

Can polyamide strips thermally break aluminum extrusion assemblies?

Yes.

Structural insulating polyamide strips have been utilized for thermally breaking aluminum extrusion assemblies for over 30 years and have been in use in north america for over a decade. Polyamide strips are available with many configurations to meet different performance specifications. Creating a thermal break utilizing a polyamide strip system entails a 3 step process.

1. Profile knurling

2. Strip insertion

3. Crimping

The Function of Thermal Break Strips in Window

Broken bridge heat-insulated aluminum alloy doors and windows is to divide the original whole-body aluminum alloy profile into two on the basis of traditional aluminum alloy doors and windows. The overall heat-insulating profile enables the heat-insulating strip and the aluminum alloy to jointly bear the load caused by the glass's own weight, wind pressure and temperature stress. Therefore, the use nature of the heat insulation strip determines that it must have high strength and excellent stability at the same time, otherwise it will easily cause doors, windows and curtain walls to break and fall off, causing major quality and safety hazards.

The word "bridge" in the name "broken bridge aluminum" means "hot and cold bridge" in material science, and the word "broken" stands for action words, which means "cut off the hot and cold bridge". Specifically speaking, aluminum alloy is a metal medium with strong thermal conductivity. When it collides with the temperature outside the house by a large difference, the aluminum alloy becomes a "bridge" for heat transfer. Using this type of material to make doors and windows, it will have Poor insulation too. However, the broken bridge aluminum is to disconnect the aluminum alloy from the middle, and the thermal conductivity of the plastic will be weaker than that of the metal. The disconnected aluminum alloy is connected together with hard plastic, so that the heat will not easily flow to the whole. material, so the heat insulation will become better, which is the origin of the name "broken bridge aluminum (alloy)".

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.

Characteristic of polyamide strips

Polyamide thermal breaks are extruded in dry state but they absorb moisture from the environment after the production as time passes. Moisture level depend the following conditions:

- Ambient temperature

- Ambient humidity

- Storage period

During the summer time, when the temperature and humidity in storage area are higher than usual, the insulating profiles absorb more moisture than in the remaining seasons, even stored properly.

How to storage polyamide thermal break strips?

First, Store profiles horizontally in order to prevent bending or twisting the material, otherwise long storage periods cause permanent sagging. Support long lengths.

Second, Maintain ambient temperature in the range from 15 to 20 °C.

Third, Protecting against moisture.

Package

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. The length usually is around 300-600 meters per roll.

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.
