At present, aluminum doors and windows are very popular in the selection of home decoration products. First, because aluminum is very light, it is the best choice for frame doors and windows; second, aluminum can be customized and matched according to specific requirements.

1. Energy saving and environmental protection. Aluminum profiles have superior corrosion resistance and high strength-to-weight ratio, making them the best choice for door and window materials. Compared with the use and loss of doors and windows of other materials, aluminum alloy doors and windows have a long service life and are also the correct choice for family cost investment.

2. Sturdy and durable.Aluminum profiles are very strong and can be processed into different sizes and shapes.After surface treatment, aluminum profiles of different colors can be obtained, which are more suitable for different home improvement styles.Unique doors and windows can be designed according to the different hobbies and aesthetic views of the owners.

3. High recovery rate.Aluminum sliding windows can be recycled and reused, which is an energy-saving material.Aluminum doors and windows do not rust, fade, or fall off, and require almost no maintenance. Spare parts have a very long service life and save maintenance costs.

Aluminum profiles are widely used in the construction industry because of their environmental protection, stability, easy processability and decoration.

Aluminum alloy profiles can be divided into base materials, anodized profiles, electrophoretic coating profiles, powder spraying profiles, fluorocarbon paint spraying profiles, striped thermal insulation profiles, glue injection thermal insulation profiles and so on.

Next, I would like to introduce to you how many ways to break the bridge of aluminum profiles?
After surface treatment, the aluminum profile with high thermal conductivity is added to the internal and external high thermal conductivity materials to break the bridge, which can make the product meet the requirements of thermal insulation. there are two ways to break the bridge, namely “through strip type” and “glue injection type”.

1. Strip-piercing type.
   Tooth-cutting treatment of aluminum profiles to improve the shear resistance of profiles and heat insulation strips.
   Strip piercing-insert heat insulation strip between two profiles.
   Rolling-rolling allows two profiles to be compounded with heat insulation strips to form a new type of aluminum profile.
   Inspection-sampling test for shear resistance.
   After passing the inspection, the packing is put into the warehouse.
2. Glue injection type.
   Sealing of injection cavity-sealing of injection cavity of profile.
   Start-up preparation-the mixed sample of American Asong An and B glue is injected after testing, and the temperature of the profile and glue tank is controlled at 20-30 degrees to ensure that the temperature is not too low to cause the colloid to become brittle.
   Cutting bridge-cutting the base material at the connection point on both sides of the profile, that is, the cutting bridge, so as to form a new type of profile that meets the requirements of thermal insulation.
   Inspection-sampling test for shear resistance.
   After passing the inspection, the packing is put into the warehouse.

The real energy-saving doors and windows, not a single use of partition bridge aluminum profiles or Low-E hollow glass energy-saving materials, it is a perfect combination of the system, the comprehensive results of each link performance, indispensable, to measure the energy conservation of building doors and windows should mainly consider three elements, namely, heat loss (heat exchange), heat convection and heat conduction and radiation;

1. Convection is the circulating flow of hot and cold air through the gap between doors and windows, which makes heat exchange through gas convection, resulting in heat loss;
2. Heat conduction is the heat transfer caused by the molecular movement of the material used in doors and windows, which is transferred from one side of the material to the other, resulting in heat loss;
3. Radiation is mainly transmitted directly in the form of rays, resulting in the loss of energy consumption.

From the perspective of three elements, we should pay attention to the following aspects for real energy-saving doors and windows:

I. Design and selection of profiles.
First of all, the performance of the profiles of different materials is different, mainly because the difference of thermal conductivity determines the energy consumption of doors and windows. When you choose a material, it is very important for the design of the profile section.
In terms of energy saving, ordinary aluminum alloy profiles are still being used. because the thermal conductivity of aluminum alloy profiles is very large and the heat conduction is very fast, it is especially obvious in the cold areas of the north, such as frosting, dew, ice and dripping water in winter.
In the south, this phenomenon is only invisible to the naked eye, but it consumes a lot of energy consumption of air conditioning.

Second, the choice of glass.
We know that the loss of energy is mainly caused by convection, conduction, and radiation.
And glass is mainly thermal radiation loss of energy, so when we choose building door and window glass, in order to ensure the energy saving of the whole building, we have to choose glass reasonably.

III. Accessories.
Hardware accessories play an important role in energy-saving doors and windows, not only closely related to the air tightness, watertightness and wind pressure resistance of doors and windows, but also play a very important role in safety and other performance.
Energy-saving door and window hardware accessories should take into account the following aspects:
A) selection of hardware accessories material selection hardware accessories with good material is the basic guarantee of good quality and energy-saving doors and windows.
Hardware accessories with poor material are easy to age and break.
This can lead to inflexible opening or inability to open and close doors and windows, which not only can not guarantee the airtight performance and energy saving of building doors and windows, but also bring harm to people’s lives and safety.
B) rational configuration and design of hardware accessories for energy-saving doors and windows, a good locking multi-point locking system should be selected to ensure the synchronous deformation of fan and frame under wind pressure, and effectively ensure the reasonable coordination of sealing materials. so that the sealing strip can be kept in a strong state under pressure with good sealing performance at any time.

IV. Correct assembly.
The first few points are the requirements of several sets of door and window components, but the reasonable selection of components is very important, and the correct combination of a variety of components into a system is a perfect energy-saving door and window, so when we choose a door and window assembly factory, it is also critical to choose a door and window assembly factory with strength and experience.
