UPVC doors and frames are made of polyvinyl chloride resin as the main raw material, plus a certain proportion of stabilizers, colorants, fillers, UV absorbers, etc., through the extrusion molding materials, the portal doors is made, called UPVC doors, It has the following characteristics:



1. High processability:
In the molten state, the plastic has a relatively high fluidity, so that a precise cross-sectional structure can be formed by the mold, thereby realizing the functional requirements of the door, and a divided chamber can be formed to improve the insulation, sound insulation and drainage of the doors. The function can avoid the corrosion of the reinforced steel.

2, Energy saving:
Compared with other doors and windows, UPVC doors and frames have superior technical characteristics in terms of energy saving and improvement of indoor thermal environment. According to the Institute of Physics, the heat transfer coefficient of single glass steel and aluminum doors is 64W/M2K; single glass UPVC doors The heat transfer coefficient is about 47W/M2K; the heat transfer coefficient of ordinary double-glazed steel and aluminum doors is about 3.7W/M2K; while the heat transfer coefficient of double-glass UPVC doors is about 2.5W/M2K, doors and windows occupy the periphery of the building. 30% of the area of the protective structure, its heat dissipation accounted for 49%, which shows that UPVC doors and window have good energy-saving benefits.

3, Sound insulation is good:
The sound insulation performance of steel aluminum doors is about 19 decibels, and the sound insulation performance of UPVC doors can reach more than 30 decibels. In the increasingly noisy urban environment, the use of UPVC doors can make the indoor environment more comfortable. According to the information provided by Japan, it is necessary to reach Also to reduce the noise requirements, the distance between the building with aluminum doors and the main road must be 50 meters, and the installation of UPVC doors can reach 18 meters.

4, The appearance is good:
It can adapt to the domestic decorative effect requirements, and the human body feels more comfortable than metal. Because of the above-mentioned outstanding advantages of UPVC doors, it is getting a lot of application in China and has become a new trend in the construction field.
