As we all know windows is an indispensable part of any house, especially in the hot and humid tropical climate like in our country. More specifically, it has a function to get light, ventilation, prevent noise and prevent theft. Of course, in terms of aesthetics, windows make the house more beautiful if they are arranged logically.

With the strong development of the construction in Vietnam, the glass is the main material with aluminum in high buildings.

However, in the hot and humid tropical climate of Vietnam, glass is not always develop their strengths and rational use. Besides the outstanding features, we should also pay attention to the effects of the glass opposite.

A phenomenon occurring when using multiple glass structure is thermal effects: obscured by the effects after radiation through the house, it will make the surface heats up, followed by radiation back out. This is the result which increased temperatures and discomfort, can directly affect human health. It is the greenhouse phenomenon, ie a temperature rise in a confined space surrounded by glass under solar radiation (radiation heat transfer into the home and difficult to heat by convection out).

In urban planning design, using large diameter glass on the street should have fully account for glazing area, distance work, tree belts to limit isolated light reflected back from buildings on the street, causing glare for people and vehicles in traffic.

Glass is easily fragile, and very dangerous when it above the skyscrapers. The building regulations in our country, the building have 5th floor or higher is required to use safety glasses. Especially when the explosion occurred, its heat resistance is poor. These disadvantages are set out for the glass manufacturer responsible for improving the bearing capacity and heat of the glass. For high-rise building in the tropics, one of the design strategy is select surface materials for the project which has low heat transfer values ​​to minimize the adverse effects of radiation and light impact on the solar project. In addition, the glass material must also have affected the ability of horizontal wind load increases with building height.

Select glass for high building?

From the above requirements, we have a solution is to select safety box glass, soundproof, heat resistance.

This glass is made by: (VFG + 0.38mm PVB + 5mm 4mm Sunergy) + 6mm argon + 5mm Tempered.

According to the figure:

+ Outer layer of safety glass (5mm 0.38mm PVB + VFG + 4mm Sunergy) is composed of 02 kinds of glass joined together through the membrane film PVB (Polyvinyl butyral) transparent. Increases the strength of glass that does not change the optical properties; in case glass breaks, they will stretch out (spider style) and stick to each other lodges on the aluminum frame.

+ Inner layer of glass is usually processed into shape by design, then put in oven to melt soft spot then slowly cooled. Temper glass bearing strength than ordinary glass, so are many applications in the fields of automotive glass, aircraft, large plate glass...

Safety box glass, soundproof, heatproof has been widely used for many projects, particularly at the Big C system Hanoi, Hai Phong, office building and lease - towers 106 Hoang Quoc Viet, Group Management Board office urban Anh Dung - Hai Phong, Lilama Corporation building 93 Lo Duc, Ho Chi Minh City…

Use safety box glass, soundproof, heatproof is the best solution for saving electric power, the initial investment for the use of this product is much lower compared to the benefits it brings, so increasingly widely used in construction and the choice of the discerning investor.
