1. Low cost, compared with aluminum alloy doors and windows, it can save 30%-60% of the cost
2. The processability is strong. In the molten state, the plastic has a relatively high fluidity, so a precise cross-sectional structure can be formed by the mold.
3. Good sound insulation, the sound insulation performance of steel and aluminum windows is about 19 decibels, and the sound insulation performance of plastic steel windows can reach more than 30 decibels. The indoor noise with plastic steel windows is reduced to 32DB(A), and the effect is very good.
4. The appearance is good and it can meet the requirements of domestic decoration effect, and the human body touch feeling is more comfortable than metal.
5. Corrosion-resistant, plastic-steel windows can be used in corrosive environments such as coastal areas and chemical plants. Ordinary users can also reduce the labor and cost of maintaining paint.
6. Good heat insulation performance. The heat transfer coefficient of single glass plastic steel window is about 47W/M2K, and the heat transfer coefficient of double glass plastic steel window is about 2.5W/M2K. https://www.chinadoorswindows.com/upvc-window/upvc-casement-window/upvc-casement-window-with-grids.html
