Why is plastic steel door and window recognized as the best energy-saving door and window in the world

Plastic steel doors and windows are loved by people for their beautiful appearance, corrosion resistance, corrosion resistance, waterproof, heat insulation, easy maintenance and other advantages, and are recognized as the best energy-saving doors and windows.

Steel plastic doors and windows are rods (Profiles) made of PVC (PVC) resin and more than ten kinds of additives and extruded by extruder and die; The rods are cut into rods.
Install the doors and windows assembled by reinforcing steel, screw connection and sealing strip, hardware, accessories and glass.

Why are plastic steel doors and windows recognized as the best energy-saving doors and windows? According to relevant regulations, the energy saving effect mainly includes three aspects.
1. Energy saving of production process. It is reported that the energy consumption of producing PVC profiles with the same weight is 1 / 4 of that of steel. 1 / 8 of the aluminum content.

2. Energy saving through recycling. For a long time, people only think that metal doors and windows can be recycled. However, the recycling of plastic doors and windows is more energy-saving.
As a result, plastic doors and windows do not need to be melted and cast like recycled metal doors and windows In rolling and other processes, only the waste materials need to be crushed or mixed with new extruded raw materials for regeneration. The material can be used to make floors, park chairs and other products.

3 plastic doors and windows have good thermal insulation performance and are economical. The metal heat transfer coefficient is high. If the heat transfer coefficient limit of the external window required by the relevant standards is to be reached, the bridge shall be broken.
This greatly increases the cost of aluminum doors and windows. Doors and windows made of special materials have excellent thermal insulation performance, and the limit value of heat transfer coefficient of external windows can reach 2.0W / ㎡ · K.
According to the current situation, the price ratio of plastic window and aluminum window is 1:1.8.

Ly profile factory can process and produce a variety of color profiles, single color, double color, wood grain color, etc., which can be customized according to the drawings.
Each of LY profiles is made with green environmental protection formula, advanced European production technology and industry-leading digital production line. The quality makes you impeccable.
