Sunshade Product Louver insulating glass

Hollow louver is a traditional sunshade product, which is generally opened or closed by manual rope or mechanical methods.

By using advanced technology, the blinds are installed in the hollow glass, and the blinds in the hollow glass are controlled by magnetic force, which can be easily lifted or turned 180 degrees.

The product not only saves room space, but also achieves the purpose of shading, and has the functions of heat preservation and anti-noise, while giving the building and interior a novel vision. Whether in summer or winter, the angle of the blinds can be adjusted to achieve shading or lighting and heating, which greatly reduces the energy consumption of air conditioning.

when the shutters are closed, we can save as high as 40% energy consumption. Due to the double-layer tempered glass structure, the wind resistance and external impact resistance are high, and it is more suitable for high-rise and coastal buildings. The product can also replace traditional partition walls and so on.

Louver insulating glass is a new product in which louvers are installed in the hollow glass cavity. The louvers in the hollow glass can be adjusted to your needs to make them all transparent, semi-transparent, or shading. You can also pull the lovers up to make it as all light-transmitting windows. It especially highlights the unique thermal insulation, sound insulation, anti-dust pollution, safety, and other advantages of insulating glass. It is an ideal product to solve the shading performance of building windows.

The 5 Things You Need to Know About Tempered Glass

Why should the glass be tempered?

  1. After the glass is tempered, its strength is several times higher. Its bending power is 3 to 5 times that of normal glass. Its impact strength is 5 to 10 times that of normal glass, which improves stability and safety simultaneously. The tempered glass can generally withstand drastic temperature changes of more than 150LC, significantly preventing thermal cracking.
  2. It is safe to use, and the load-bearing capacity is increased to improve the fragile nature. Even if the toughened glass is damaged, there are small fragments without acute angles, which significantly reduces the damage to the human body after the accidental broken glass.

How is the glass tempered?

The ordinary glass is cut to the required size and then heated to about 700 degrees close to the softening point of the glass, and after that quickly and uniformly cooled (usually 5-6MM glass is heated at 700 degrees for about 240 seconds, and then cooled down for approximately 150 seconds.), the glass is heated to an appropriate temperature and then quickly cooled, causing the glass surface to shrink sharply, resulting in compressive stress. However, the middle layer of the glass cools slowly, and it is a bit late to shrink, so tensile stress is formed, which makes the glass obtain higher strength.

What are the disadvantages of tempered glass?

  1. The toughened glass can no longer be cut and processed. The glass can only be processed to the required shape before tempering.
  2. Although the strength of tempered glass is stronger than that of ordinary glass, there’s still have the possibility of spontaneous explosion (breaking by itself) when the temperature difference changes significantly. In contrast, normal glass does not have the chance of spontaneous explosion.

Why does tempered glass explode?

Because the glass raw material contains nickel sulfide crystals, it is impossible to avoid the existing manufacturing technology in the world entirely. This kind of nickel sulfide crystal has two forms, A form and B form. Under particular time and temperature conditions, the A form will change to the B form, and the volume of the B form is 3-5 times the volume of the A form.

Although the volume of this kind of crystal is tiny, if this kind of crystal becomes B-shape inside, the increase in volume will affect the internal compressive stress balance of the whole piece of glass and cause the glass to break. There is no compressive stress inside an ordinary one. The deformation of its nickel sulfide crystals will not cause these problems. There is enough space for it to deform.

glass self-exploration

How to reduce the spontaneous explosion rate of tempered glass?

The self-explosion rate of tempered glass recognized in the industry is 3‰-5‰.

  1. Reduce glass impurities and improve purity from the production source.
  2. In the glass tempering process, use better equipment to function to make sure the internal stress of the glass is uniform, which leads to a lower spontaneous explosion rate.
  3. In the case of reaching the required strength, control the stress value of the tempered glass. The lower the stress, the lower the self-explosion rate.
  4. Do hot-dip treatment. After tempering, put the glass in a furnace at 300°C for about 8 hours to simulate extreme environmental factors so that the potential self-exploration glass may explode in advance, which can be understood as detonation treatment. Note, however, that there is still a risk of self-explosion of glass after hot dipping, and the self-explosion rate of glass is one in a thousand.
  5. Use ultra-white glass. When the glass is produced, the nickel sulfide impurity inside the glass is eliminated through a chemical displacement reaction. The self-explosion rate of this glass after tempering is one in 100,000.

How to choose glass types for building glass walls and roofs

Building Glass Performance with the perfect quality of manufacture and performance of the product, glazed external walls are used to maximise natural light within rooms, further reducing the running costs of these highly energy-efficient homes.

Low U-values of insulated glass

Excellent thermal insulation was also part of the performance. The low U-values delivered by our insulated glass ensured impressive low energy performance, which helped the development achieve the Code for Sustainable Homes standard. We exported many containers of the glass roof in recent years. I think our skylight price is competitive as importing cost is not too much. We know the retail skylight price may be ten times compared with our quotation in the retail market.

skylight glass

Our glass rooflight competitive in low U value (Triple glazed U value 0.8 even Quad glazed 0.58). Established in 2000, we exported large quantity glass products in the past 18 years. Our direction is to focus on branded glass products, be a Strategic Partner with Pilkington, and mainly supply building glass to famous real estate companies in China. As building glass quantity is huge but requirement strictly, we can’t get approval from them unless top quality.

What is reflective Glass

We also provide reflective glass for commercial and residential buildings.

Coated reflective (including heat reflective glass, low-e glass (Low-E), conductive film glass, etc.)
Reflective glass, also known as reflective glass. Coated glass is to coat one or more layers of metal, alloy or metal compound film on the surface of the glass to change the optical properties of the glass to meet certain specific requirements.

Heat-reflective glass is generally coated with one or more films composed of metals such as chromium, titanium or stainless steel or their compounds on the surface of the glass so that the product is rich in color, has an appropriate transmittance for visible light, and has a higher resistance to infrared reflectance, it has a high absorption rate of ultraviolet rays, so it is also called solar control glass, which is mainly used in construction and glass curtain walls;

Low-E glass (Low-E) is a thin film system composed of multiple layers of silver, copper, tin and other metals or their compounds coated on the surface of the glass. The product has high transmittance to visible light and high reflectivity to infrared. It has good heat insulation performance and is mainly used in construction, automobiles, ships, etc. Due to the poor film strength, it is generally used as a hollow glass. The heat passing through the glass is bidirectional; that is, heat can be transferred from indoor to outdoor and vice versa, it is carried out simultaneously. It is only a problem of poor heat transfer. In winter, the indoor temperature is higher than the outdoor temperature, and insulation is required.

building glass

In summer, the indoor temperature is lower than the outdoor temperature, and glass must be insulated. Low-E glass can keep heat and heat insulation. The visible light transmittance of Low-E glass ranges from theoretically 0%-95% (it isn’t easy to achieve with 6mm white glass), and the visible light transmittance represents indoor lighting. The outdoor reflectance is about 10%-30%, and the outdoor reflectance is the visible light reflectance, which represents the intensity of reflection or the degree of dazzling.

Two current production methods of Low-E glass

Online high-temperature pyrolysis deposition methods, such as PPG’s Surgate200, Ford’s Sunglas H. R”P”. These products, are completed during the float glass cooling process. Liquid metal or metal powder is sprayed directly onto the surface of the hot glass. As the glass cools, the metal film layer becomes a part of the glass.
The main advantage of the offline vacuum sputtering method is that the “U” value of the “Low-E” hollow glass produced by sputtering is better than that of the pyrolysis product. Still, its disadvantage is that the silver oxide film layer is very fragile.

Why Digital printed glass should be used in curtain walls?

Every year, there are nearly one billion deaths of migrating birds collide with windows and glass curtain walls. With the continuous increase using of glass curtain walls, the impact is becoming huge.

What’s the solution to protect migrating birds? Why is the normal glass dangerous to them? Let’s dive in.

Glass characteristics – why it is dangerous to birds

Three characteristics of glass make it dangerous to birds:

  1. Reflective: Especially in the daytime, the glass will reflect the normal scene, causing the bird to hit the glass.
  2. Transparency: Also at some time in the daytime, the glass is not so reflective, birds will try to pass through the glass.
  3. Beacon effect: Buildings with active lighting are particularly harmful to birds that are active at night, especially under rain or hazy conditions. Birds descend to a lower height to maintain their position, and they are attracted by the lights of buildings with tragic consequences.

The American Bird Conservation Association has researched and developed guidelines for glass designs to protect birds. These designs have been scientifically proven to be a visual deterrent. The bird anti-strike glass pattern is defined as a pair of horizontal elements (separated such as dots, lines, outlines, etc.) by no more than 2 inches with vertical elements separated by no more than 4 inches. Birds in flight see these visually and will avoid collision accidents.

Digital printed glass can protect birds

Digital printed glass provides unlimited design possibilities while protecting birds. This is a fast, accurate, and cost-effective solution, especially for graphics that contain more complex designs, more colors, and non-repetitive printing on the entire panel.

Studies have shown that birds can perceive colors, which means that colored and random patterns will greatly reduce the number of collisions. These inks can be applied to the inside of the glass (face 2), but printing on face 1 is still the most powerful solution.

Fortunately, the face 1 surface ink can also be used in the digital world, which allows us to print complex designs on the outer surface. Just like screen printing inks, this high-performance solution reduces glare and reflections on the glass, providing a safer barrier for birds. The design patterns are endless, and it is easy to adapt to the required standards.
