The excellent performance of U-pvc doors and windows(一)

1. Insulation and energy saving 

    Plastic doors and windows materials are hot bad conductor, heat transfer coefficient is only steel 1/357, aluminum 1/1250, with good insulation, thermal insulation properties. 

    In addition, the plastic steel cross-section are hollow multi-cavity structure, composed of several small space closed air compartment, the purpose is to make full use of air excellent thermal insulation properties, so that the thermal conductivity is further reduced. The so-called two-chamber, three-cavity, four-cavity profile, that is, the width of the profile of the number of layers. The more layers, the better the insulation performance. Although the window frame material only 30 ~ 40% of the windows and doors, but under the same conditions, plastic doors and windows than steel doors and windows and aluminum doors and windows thermal conductivity 23 ~ 40% lower. 

 

In addition, the relevant departments of the test: single glass plastic doors and windows of the K value can reach the national standard 4, double glass plastic doors and windows of the K value can reach the national standard 2, and single glass ordinary steel doors and windows and aluminum doors and windows K value only reached the national level 6 standard, double glass ordinary steel doors and windows and aluminum doors and windows of the K value only to the national level 4 standard. Plastic doors and windows were higher than ordinary steel doors and windows and aluminum doors and windows two grades.


Physical performance
    Plastic doors and windows of the physical properties mainly refers to: PVC plastic doors and windows of the air permeability (air tightness), rainwater leakage (watertight), wind pressure performance and insulation and sound insulation performance. As the Upvc doors and windows profiles have a unique multi-chamber structure, and by the welding process from the doors and windows, upvc doors and windows in the installation of all the gaps are equipped with doors and windows sealed strips , so has good physical properties.
