Product Description

Good Quality Sound Proof Heat Insulation Strips Nylon Polyamide66 Glass Fiber Reinforced Profiles
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.

Product Advantage:
1.Effectively increased thermal in the system property insulation.
2.Reduces condensation on the window.
3.Sound insulated.
4.Improve comfort and living condition.
5.Possible double color coatings provide better aesthetic effect.
6.Various shapes will be designed for the customer's requirements.
7.The working temperature of the thermal insulation strip is 220°C, Melting Point reaches to 246°C. This enables coating process after assembly of composite profiles.
8.High corrosion-resistance, weather-resistance, heat-resistance, alkali-resistance and long life of usage.
9.Linear thermal dilation coefficient almost identical to that of aluminium profiles.

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)".
