Bridge cutoff aluminum PVC insulation strip is a common decorative material. How long is the service life of bridge cutoff aluminum PVC insulation strip?
Now, the bridge cutoff aluminum door and window thermal insulation strips can be used for more than 20 years.
There are three types of bridge cutoff aluminum insulation strips, namely PVC, PA and PU. The first two are extrusion processes, and the second is glue injection process. The state stipulates that PA66 is used as the raw material of the aluminum alloy bridge cutoff window, otherwise the service life of the window will be greatly shortened. The service life and finished product quality of the other two insulation strips are not as good as PA.
In order to reduce the cost in the market, poor enterprises will use relatively cheap PVC plastic insulation strips, so they should learn to identify the differences between PA and the other two types of insulation strips when selecting. Generally, it can be distinguished by the following two points. When you see the luster, the surface of PA66 heat insulation strip is frosted, and the color is anti black. In contrast, PVC insulation strips look very smooth and bright. The second is the degree of combustion. The insulation strip of PA66 does not burn, but after PVC burns for a period of time, you will see a small flame burning, and you will smell the smell of plastic.
The thermal insulation bridge cutoff aluminum alloy profile and hollow glass structure can reduce the heat conduction through the doors and windows, so that you will not feel hot in summer sunshine and cold in winter when the wind is cold. The internal surface temperature of aluminum door and window profiles with heat insulation strips is close to the indoor temperature, reducing the possibility of indoor moisture condensation on the profile surface due to supersaturation.
The bridge cutoff aluminum insulation strip can be used for more than 20 years. There are three types of bridge cutoff aluminum door and window insulation strips, namely PVC, PA and PU. The first two are extrusion processes, and the second is glue injection process. The state stipulates that the aluminum alloy bridge cutoff window made of PA66 as the raw material will shorten the service life of the bridge cutoff window. The service life and quality of the other two insulation strips are not as good as PA.
The insulating strip is the core component of the insulating strip. The utility model is a bridge breaking on the heat transfer path of the aluminum profile, which reduces the heat transfer of the aluminum profile; It is also the structural connection of aluminum profiles on both sides of the insulation strip. Through its connection, the three parts of the insulation strip become a whole and bear the load together. Unlike adhesive tape, it is a new composite material made by mechanical rolling and cannot be replaced separately. Only the entire profile can be replaced together. The internal structure quality of the bridge cutoff aluminum insulation strip is the guarantee in principle, ensuring the strength and stability of the profile.
After reading this article, you need to know more. Generally speaking, it can be used for about 20 years and has a relatively long service life. The bridge cutoff aluminum insulation strip is the core component of the thermal insulation profile, which is very good.
