Abstract: Today's society advocates energy saving and environmental protection. For our general homes, windows are a very important part of building heat preservation and insulation, and these functions are just the key points of windows for home energy saving. The editor below introduces you in detail the knowledge of purchasing energy-saving doors and windows from the four aspects of purchasing energy-saving windows, selecting window accessories, and new ventilation, and teaches you how to carry out green protection for your home.

What are energy-saving doors and windows

Energy-saving doors and windows are a kind of doors and windows to increase the lighting and ventilation area or to express the character characteristics of modern buildings. Energy-saving doors and windows will improve the optical performance, thermal performance and sealing of materials, and improve the structure of doors and windows to achieve the expected effect.

How to choose energy-saving windows

If you want to buy a good energy-saving window, it is very important to choose from the profile to the sealing, and then to the glass. Let’s refer to these professional knowledge first!

Profiles: the key to improved insulation performance

Window profiles with good thermal insulation performance are the key to improving the thermal insulation performance of windows. It requires window profiles not only to have good thermal insulation performance, but also to have good anti-deformation capabilities and anti-aging capabilities. Once the rigidity of the window does not meet the requirements, it will inevitably lead to structural deformation of the window and lax closing, which will seriously reduce the sealing performance of the entire window.

The thermal insulation coefficient of various profiles is also the key point of energy-saving windows, let's take a look at the thermal insulation coefficient of window profiles.

Types of glass for windows: pay attention to the effect of heat preservation

Energy-saving glass windows can generally be divided into three types: heat-absorbing glass, insulating glass, and heat-reflecting glass. Generally speaking, in severe cold areas, try to choose insulating glass. This material mainly controls heat conduction and can play a good heat insulation effect; in hot summer and cold winter or hot summer and warm winter areas, it is recommended to choose heat-absorbing glass and heat reflection glass. Glass, try to control the solar energy entering the room, control the room temperature, so as to reduce the air conditioning load and achieve the purpose of energy saving.

Choose the accessories of the window: the energy saving effect has an impact

If you want to have energy-saving windows with good performance, the accessories must not be sloppy at all. You must choose high-quality metal hardware. At the same time, the opening method of the window also has a great impact on energy-saving performance. You must choose the appropriate opening according to your needs. Way.

Window hardware selection: high-quality metal is king

The hardware of high-end windows is made of metal, and its internal strength, appearance and usability all directly affect the performance of the window. Many middle and low-grade plastic-steel windows use plastic hardware, and there are great hidden dangers in their quality and service life. Hardware parts mainly identify their flexibility, airtightness, wear resistance and corrosion resistance, while accessories mainly consider the lining steel placed in the profile cavity. For plastic steel windows, the best lining steel should be galvanized A3 Steel, with a wall thickness of at least 1.2 mm.
