Double Pane Energy-Saving Toughened Glass

Double Pane Energy-Saving Toughened Glass is an insulating glass unit composed of two pieces of glass, at least one of which is energy-saving coated glass, and toughened glass is used as the base material in accordance with building safety requirements. A closed cavity is formed between two pieces of glass through spacer bars. The interior of the cavity can be filled with dry air or argon gas, thereby changing the heat transfer mode of the glass system.

Reduce the transfer of thermal radiation

Energy-saving coating can reduce the heat exchange of far-infrared radiation, thereby lowering the heat transfer between the indoor and outdoor environments.This feature is particularly practical for areas that are hot in summer, cold in winter or have a large temperature difference between day and night.

Improve indoor comfort

The performance of window glass can affect the temperature perception in the area near the window inside the room. Reasonable configuration of double pane energy-saving toughened glass can reduce the temperature difference between hot and cold on the glass surface, making the indoor environment more stable.

Maintain natural lighting

Energy-saving glass does not mean completely blocking light. Depending on the type of coating, a balance can be struck between heat insulation and visible light transmission.For residential and office buildings, different products can be selected according to the indoor lighting requirements.

Suitable for building energy conservation

Double Pane Energy-saving toughened glass is one of the more common glass configurations in modern energy-saving doors and Windows and can be used in conjunction with high-performance window frames and sealing systems.

The performance of architectural glass is not simply "the more transparent, the better".

Double pane Energy-Saving toughened glass usually needs to take into account simultaneously:

Visible light transmittance (VLT)

Decide how much visible light can enter the room.

Solar heat gain coefficient (SHGC)

Reflect the extent to which solar energy enters the interior of buildings.

Heat transfer coefficient (U-value)

Used to evaluate the heat transfer performance of glass systems.

Reflectance

It affects the visual effect of the building facade.

There are certain trade-offs among different parameters, so the product should be selected based on the project location and the building's purpose.

Residential buildings

It is suitable for aluminum alloy doors and Windows with thermal break, floor-to-ceiling Windows, sunrooms and high-performance residences.

Office building

Suitable for office buildings, business centers and glass curtain walls.

Hotel

It can be used for guest room Windows, public area curtain walls and large glass facades.

Commercial building

Suitable for buildings such as shopping centers, exhibition halls, and commercial complexes.

High-rise buildings

The thickness and structure of the glass can be customized according to the wind load and requirements of the curtain wall system.

Energy-saving building

It is applicable to green buildings, low-energy buildings and high-performance building envelope systems.

The hollow layer is an important component of the double pane glass structure.

Common configurations include:

6A, 9A, 12A, 16A, 20A, 24A

It is not the case that the thicker the hollow layer, the better the performance will definitely be.

In practical applications, it is necessary to match according to the glass size, the characteristics of the Energy-Saving film layer, the filling gas and the entire window system.

For example:

6mm + 12A + 6mm

Suitable for some conventional door and window projects.

And:

6mm Energy-Saving+ 16A Argon + 6mm

It is one of the more common configurations in building energy conservation projects.

For high-performance buildings, warm-edge spacers can also be combined to further reduce the thermal bridge effect at the glass edges.

Package

1. Paper and Cork liner will be put between every two glass to prevent them hurt each other.
2. Iron belt for consolidation.
3. Under wooden crate there will be legs for forklift easy loading and unloading.

Q1: What are the differences between double pane Energy-Saving toughened glass and ordinary double-layer insulating glass?

The main difference lies in the addition of a Energy-Saving low-emissivity film layer on the glass surface. Ordinary insulating glass mainly relies on the hollow cavity to reduce heat transfer, while Energy-Saving insulating glass further controls radiative heat exchange. Therefore, it is more suitable for projects that have requirements for building energy-saving performance.

Q2: Does double pane Energy-Saving glass definitely need to be filled with argon gas?

Not necessarily. It can be filled with dry air or argon gas according to performance requirements. For projects with high energy-saving requirements, the combination of Energy-Saving and argon gas usually has more advantages.

Q3: What are the common specifications of double-layer Energy-Saving toughened glass?

Common structures include 5mm+12A+5mm, 6mm+12A+6mm and 6mm+16A+6mm, etc. The actual specifications need to be determined based on the size of the glass, wind load, building energy-saving requirements and the door and window system.
