Both brands are Guangdong Foshan brands. I haven't used the doors and windows of the Royal School, so I don't know much about them. The doors and windows of my two houses are Hennessy. What I see is that Hennessy doors and windows have good sealing performance. The doors and windows can save heating in winter and save electricity in summer. Anyway, after using Hennessy doors and windows, in summer, you can turn on the air conditioner for less than 3 hours a day, and you can save dozens of dollars on electricity bills a month.
The sound insulation effect of the Hennessy window is good, the color is also positive, and the cost performance is very high. The Royal doors and windows are the most powerful in advertising. The Internet is offline, and the price is higher than Hennessy. Hennessy Chinese first-line brands have good sound insulation and heat insulation effect. My family bought Hennessy doors and windows, which are quite good.
Royal doors and windows were established in 2007. Hennessy doors and windows are established in 2004, a brand owned by Foshan Xuhui Hardware Development Co., Ltd. Before its establishment, it was engaged in the research and development and sales of door and window hardware.
If the sound effect is high, you can choose Hennessy. If you want to act as a door and window agent, you can use the royal doors and windows. After all, there are many doors and windows of the royal family. However, for individual user families, the editor is still recommend Hennessy.
