Preface

Since the first building with metal frame glass curtain wall in 1864, such facade system has become more and more popular!

It is estimated that the global aluminum curtain wall market will reach US $60 billion by 2026. Because the curtain wall is a non-structural peripheral protection system, with good plastic aluminum profiles and high transmittance glass, it has become the mainstream trend of curtain wall for many years. However, with the continuous upgrading of the concept of "low carbon, green and environmental protection", human research and exploration on curtain wall design, construction and materials have never stopped.

In 2023, what kind of panel material will lead the development trend of curtain wall?

01·More complex shapes

With the progress of technology, more curved, special-shaped and inclined curtain wall designs are presented in real life. The building curtain wall is also more eye-catching and unique, but the special-shaped curtain wall cannot be separated from the support of special-shaped materials:

Metal

Because of the material properties of metal, it can well adapt to more complex curtain wall shapes.

Double curved aluminum plate:

Hyperbolic aluminum panel or a kind of aluminum veneer to form hyperbolic profile through factory prefabrication is a sophisticated technology in the field of aluminum panel curtain wall, which has excellent performance in both large public buildings and small single buildings.

It can also make hyperbolic metal curtain wall and hyperbolic honeycomb aluminum plate. The hyperbolic stainless steel and so on will not be described too much here, and a "soft" metal curtain wall can also bring a refreshing facade effect.

Metal mesh curtain:

Metal curtain, also known as metal bead curtain, metal cloth is a new modern decorative material made of high-quality stainless steel, aluminum magnesium alloy wire, brass, carbon steel and other alloy materials.

In the past, metal mesh curtain was usually used in interior and landscape, but the application of metal mesh curtain in facade curtain wall would bring unexpected effects.

Glass

In building curtain walls, metal and glass have always been inseparable curved glass. As the name implies, curved glass is easy to make glass into curved surface and bend glass into curved surface, but how to install large-format glass on the facade is the challenge of curved glass curtain wall.

The new LV store in Ginza, Tokyo, has a hyperboloid glass+hallucinogenic film water-light facade, which not only stands out in the block, but also shows the brand temperament.

Cement

When it comes to special-shaped curtain wall GRC, it has to be mentioned that GRC (glass fiber reinforced concrete) glass fiber reinforced concrete, abbreviated as GRC, is a lightweight, high-strength, high-tenacity and multi-functional inorganic composite material made of alkali-resistant glass fiber as reinforcement, sulphoaluminate low-alkalinity cement as binder and mixed with appropriate aggregates to form the base material through spraying, mold casting, extrusion, slurry flow and other production processes.

Stone

As the name implies, soft stone is a kind of flexible stone-like material, which is made of renewable and environmentally friendly active soil. The thickness of the finished product is only 2-3mm, and the texture is flexible. It can perfectly decorate various curved shapes. It is also easy to pave and paste irregular shapes, with a minimum radius of 200mm.

02·Higher energy saving performance

As the world becomes more aware of the need for global warming and energy conservation, and as China's "double carbon" goal requires more and more energy efficient curtain walls with lower U value and more effective thermal insulation.

Glass

Low-e glass

Low-e glass, also known as low-radiation glass, is a kind of film product composed of multi-layer metal or other compounds coated on the glass surface. Generally, there are single-layer, double-layer and three-layer hollow Low-e glass, which has excellent heat insulation effect and good light transmittance compared with traditional glass.

Vacuum glass

Vacuum glass is a new type of glass deep-processing product. It is a structure of vacuum glass developed based on the principle of vacuum flask. Similar to insulating glass, the difference is that the gas in the vacuum glass cavity is very thin, almost close to vacuum, and has better heat preservation and noise reduction functions.

03·Sunshade reduces solar gain

With the large area of glass in many exterior walls today, the potential problem of solar energy gain comes with it. In order to avoid the need for expensive air conditioners, the importance of shading the facade is self-evident.

External facade sunshade shutter

The building facade louver, as a common form of facade shading, can maximize the facade effect. The common materials used for sunshade are: aluminum plate, wood plate, ceramic plate and other aluminum-plastic composite plate/honeycomb aluminum plate. Aluminum-plastic composite plate and honeycomb aluminum plate are very common shading materials for exterior facades, with light weight and small compliance. Strong gloss. Compared with aluminum-plastic panel, honeycomb aluminum panel is more flat and has better fireproof performance.

High-temperature heat-curing wood fiber board is one of the greatest advantages of artificial decorative board. It overcomes the disadvantages of traditional natural materials such as instability and poor weather resistance, and saves and protects wood resources.

Ceramic plate

The ceramic plate uses natural clay as raw material and adds a small amount of quartz, pumice, feldspar, color and other ingredients. After a series of firing, the ceramic products are made of renewable materials. The dry hanging and installation keel of the ceramic plate curtain wall is less, the installation and replacement are convenient, and the shape is rich, and the weight is light, which can shape the texture and line sense.

04·Larger panel

In recent years, people's aesthetics tend to be simple, and the parting and structure of building curtain walls are also simplified. More and more seamless curtain walls have also verified this point. In addition to making every effort to hide the parting in the process, the structure shapes the curtain wall image of a larger overall panel. The strength and size of curtain wall materials are also breaking through.

Tempered laminated glass

Many glass processors are now able to produce oversized glass, which makes it possible to make larger glass panels. This can be combined with toughened glass, and then glued to the huge insulating glass unit. The curtain wall of Apple's flagship store, which is well known to all, uses super-sized subway ultra-white heat strengthened laminated glass.

Stone

Stone is one of the oldest building materials, but limited by the processing method and raw material characteristics, the size of natural stone can not be very large, but there is a kind of artificial stone - clay guest stone, which can reach the maximum size of 1.8 * 2.7m. The clay guest stone is made by using cement as the main cementing material, selected quartz sand aggregate, inorganic pigment, fully mixed, and the waste material process. It breaks through the traditional organic resin material, does not contain organic materials, and can customize the texture.

05·More transparent facade

In fact, our era is dominated by glass architecture. It is open, free, full of modern and artistic sense, and at the same time has strong plasticity. In addition to its ethereal temperament, it is often praised as the "fourth form of material". With the development of glass curtain wall, it becomes more and more clear and transparent.

Ultrawhite glass

Generally, glass contains a certain amount of iron, which will lead to different degrees of green visual effect. The content of ferrite in ultra-white glass is 10% or even lower than that of ordinary glass. With the appearance characteristics similar to colorless crystal, it can form a more transparent curtain wall effect.

06·High flatness glass

In modern glass curtain wall buildings, because the deformation of glass flatness is not well controlled, there are glass curtain walls with deformed images all over the street. By controlling the original glass sheet, tempered glass, hollow lamination, unit framing, construction accuracy and other methods, the problem of glass flatness can be well solved, especially to improve the flatness of tempered glass. At the same time, installation factors will also directly affect the flatness of the curtain wall.

07·Various composite and filler plates

Curtain wall materials are now more inclined to composite materials, filler materials and other composite materials, which have the advantages of various materials, such as rich effects, light weight, convenient installation, and can also have thermal insulation, fire protection and other functions.

Insulation integrated board

The heat preservation and decoration integrated board is also called the energy-saving heat preservation and decoration integrated board. It is mainly composed of thermal insulation layer, base plate, decorative coating bonding layer, anchor parts, sealing materials, etc., and is widely used in building exterior wall thermal insulation and decoration.

08·PV building integration

Smart curtain wall technology began to appear, such as incorporating photovoltaic cells into glass curtain walls, which absorb solar energy in the daytime and emit light generated by stored electricity at night.

09·Dynamic curtain wall

Dynamic curtain wall can make the facade produce dynamic effects, especially the wind curtain wall makes use of natural phenomena. The interaction between wind and curtain wall makes the building surface produce dynamic effects, which can present many or countless expressions of beauty.

Pneumatic curtain wall

Wind curtain wall is also called wind bell curtain wall. Its principle is simply to use dynamic wind to simulate the effect of wind blowing. Its structure is relatively simple.

Usually, stainless steel cables are used to chain the metal pneumatic pieces to fix the unilateral limit of the pneumatic pieces, which can only move in one direction, making the wall float in the air, light, flexible, natural and smooth.

10·Self-cleaning curtain wall

As the building becomes higher and higher, the cleaning and maintenance of the facade becomes more and more important and difficult, so the use of self-cleaning materials will become the trend of the use of curtain wall materials in the future.

Self-cleaning materials

KMEW photocatalyst ceramic plate, photocatalyst is a kind of nanometer titanium dioxide, which is the general name of photosemiconductor materials with photocatalytic function.

It is coated on the surface of the substrate under the action of ultraviolet and visible light, producing a strong catalytic degradation function. Therefore, the photocatalyst ceramic plate has the "dirt decomposition function", "air purification function", and the "super hydrophilic function" of using rainwater to wash dirt. In addition, the "high weather resistance" can inhibit the fading caused by ultraviolet light.

Self-cleaning glass

The glass surface is coated with a thin layer of transparent, strong hydrophilic and photocatalytic mineral material. In natural light, the glass will dissociate the organic dirt to form a hydrophilic surface, and then the rainwater will form a water film on the surface to wash the glass to remove the dissociated dirt and residual dust.
