Qingdao Morn Building Materials Co., Ltd is a turnkey supplier of tempered glass, laminated glass, and insulated glass located in Qingdao, China. The document discusses low-emissivity (LOW-E) glass, which has a metal or metal oxide coating that reflects infrared heat while allowing visible light to pass through. It describes three main types of LOW-E glass - high-transmittance, solar shading, and functional - and provides details on their characteristics, suitable applications, and Morn's product offerings.

Low e glass introduction
Low-emissvity glass (also known as LOW-E glass) is a multi-layer metal or metal oxide film coated
on a glass surface, one or two layers of which are mainly Ag-based. It can effectively reduce solar
energy absorption or control energy loss, and greatly reduce the heat transfer coefficient of glass. It
can reflect 50%~80% of the heat transferred by glass, especially far-infrared radiant heat, while
allowing all or part of visible light to pass. Coated glass. Insulated glass(double glazed
units) processed with LOW-E coated glass not only has good energy-efficient and heat-insulating
effect.
According to its heat insulation and transparency effects, it can be roughly divided into three categories:
high-transmittance LOW-E glass, sun-shade LOW-E glass, and solar shading LOW-E glass.
According to the production method: it can be divided into online and offline low e coating.
1, high transmittance LOW-E glass
Features:
a, high visible light transmittance – good indoor lighting, energy efficient, good appearance and
permeability.
b,high far-infrared reflectivity – heat transfer coefficient K value (or u value) is low, thermal insulation
performance is good.
Product suitability:
Due to its good visible light transmittance, the product is suitable for high-permeability exterior design in
any area, which makes the building naturally light and has high transparency. Its extremely high far-infrared
reflectivity makes it suitable for energy-efficient glass curtain wall, especially for cold regions.

2, Solar shading LOW-E glass
Features:
A, moderate visible light transmittance – visible light transmittance is generally 50% -70%, on the one
hand does not affect the indoor natural lighting.
B, extremely high far-infrared reflectivity – heat transfer coefficient K value (u value) is lower than high
permeability LOW-E glass, better thermal insulation performance, can effectively limit indoor and outdoor
far-infrared heat energy into and out of the room.
C, lower solar transmittance – glass sunshade coefficient SC <0.5, can effectively prevent solar radiation
from entering the room.
Suitable type
It can be seen from the above characteristics that the product can effectively block the heat of the sun
from entering the room in summer and reflect the background infrared radiation from the outside. Although it
restricts the entry of some solar thermal energy in winter, the solar energy intensity in winter is only about 1/3
of that in summer, which has little effect and can effectively block the indoor heating equipment and the

infrared heat energy emitted by the human body. A variety of reflective colors, decorative effects, the product
can be widely used in the southern region.
3, functional LOW-E glass
Morn pays great attention to product quality and product functionality, and has developed many functional
composite low e coated glass.
(1) Double silver LOW-E glass
Double silver LOW-E glass is advanced LOW-E glass, the film layer is more complex, not only has a high
transmittance, but also has a very low solar transmittance, which maximizes the filtering of sunlight into a cold
light source. The contradiction between high visible light transmittance and low solar energy transmittance is
more suitable for cold regions in the north.
(2) ceramic fritted LOW-E glass
With the advancement of technology and the improvement of living standards, people’s requirements for
products are not only energy efficient, but also require artistic effects. For this reason, our company’s R&D
center has developed a series of various patterns of ceramic fritted glass with low-e coating.
(4) temperable LOW-E glass
The glass forms a strong physical and chemical bond with the LOW-E film layer, which ensures mutual
understanding and does not oxidize the film layer during tempering or bending. Detachment ensures that the
glass can be hot processed and processed off-site.
Triple silver low e glass
Triple silver low-e contains 3 layers AG coatings inside which decrease glass solar coefficient significantly
without affecting the light transmittance.Morn has triple silver low e coatings that can compete PPG solarban
70XL, Solarban 90 to suit worldwide projects.
