With the continuous improvement of the quality of life, people have clear requirements for the quality and performance of the house. The energy-saving performance, safety performance, noise reduction, sun protection, comfort and durability of building doors and windows are increasingly valued. Door and window products, in addition to pay attention to the obvious parts of doors and windows, such as the quality of aluminum, glass, accessories, etc., but also pay attention to the realization of the comprehensive performance of these door and window components.
Most people think that the purchase of high-quality doors and windows, pay attention to the quality of the obvious parts of doors and windows such as aluminum, glass, accessories, etc., but the professional performance requirements of the doors and windows are not understood at all, more concerned about the product Quality, cost-effective and other factors, the initial consumption ideology that high-quality doors and windows are equal to high-performance doors and windows.
In fact, high quality doors and windows = high quality profiles + glass + accessories strips + processing technology + installation process +…
High performance doors and windows = high performance profiles × glass × accessory strip × processing technology × installation process × …
Therefore, high-quality doors and windows, high-performance doors and windows.
The real system door and window is a perfect organic combination of performance system, need to consider water tightness, air tightness, wind pressure resistance, mechanical strength, heat insulation, sound insulation, anti-theft, A series of important factors such as sunshade, weather resistance, and handling feel, as well as the comprehensive results of the performance of equipment, profiles, fittings, glass, adhesives, and seals, are indispensable.
Design and selection of profiles
First, the performance of different materials is different, mainly because the difference in heat transfer coefficient determines the energy consumption of doors and windows. When you choose a material, The focus on profile design is very important. In the case of aluminum alloy profiles, ordinary aluminum alloy profiles have very high thermal conductivity and fast heat transfer. They are particularly noticeable in cold regions of the north, and there are also frost, dew, ice and drowning in the interior. The phenomenon is only invisible to the naked eye, but it consumes a lot of energy for air conditioning. Most of the red oak tree sound door and window series products are broken bridge aluminum profiles, multi-layer rubber strips, and the thermal insulation performance is very good.
Of course, whether the improvement of the profile can achieve the effect of energy saving is related to the opening form of the window type. For example, the energy-saving effect of the aluminum alloy profile of the insulated door and the window is compared. Obviously; for sliding doors and windows, the use of insulated aluminum profiles can only be said to be difficult to stand alone, because the sliding doors and windows are closed when the two window fans are not in the same plane, and there is no sealing pressure between the two window fans and around, only The overlap is overlapped by the tops, and there is a gap between the tops to form a convection phenomenon.
The choice of glass
The loss of energy is mainly caused by convection, conduction, and radiation. The glass is mainly the heat radiation loss energy, so we are choosing the building doors and windows. When making glass, to ensure the energy saving of the whole building, it is necessary to choose the glass reasonably. In response to the needs of different buildings around the world, choose the glass with the corresponding heat transfer coefficient and shading coefficient.
Take the southern region, the southern region belongs to the hot summer and warm winter zone, and the high temperature cycle is long. In the choice of glass, it is not possible to choose transparent glass with good lighting in the cold region. Low reflection, such as heat reflective coated hollow glass and Low-E insulating glass.
“Hardware accessories are the heart of the doors and windows, not the supporting role.” A person’s limbs are developed, the appearance looks good, if the heart is not good, Is it a waste person? The same is true of doors and windows. The functions of hardware accessories in energy-saving windows and doors are very important. They are not only related to the airtightness, watertightness and wind pressure resistance of doors and windows, but also play a very important role in safety and other performance. The red oak net sound doors and windows are selected by well-known brand hardware accessories, such as Germany imported good Bo handle, through 2 million reset experiments, the details determine the height, in order to enhance each user’s product experience.
The previous points are the requirements of the door and window assembly, and the correct combination of multiple components into a system is the perfect system door and window. Therefore, when we choose to join the doors and windows, it is also very important to choose the strong and experienced door and window manufacturers. For example, the red oak doors and windows are very good.
