Insulating low-e glass can be 3, 4, 5, 6, 8, 10, 12 mm thick sheet glass, air layer thickness can be 6, 9, 12 mm interval.

Thermal insulating glass

The thermal conductivity of glass is 27 times that of air. As long as the insulating low-e glass is sealed, the insulating low-e glass has the best thermal insulation effect.

Thermal insulating glass

There is a certain space between the glass of the insulating low-e glass and the glass. The frame is filled with a desiccant to ensure the dryness of the air between the glass sheets.

Thermal insulating glass

The distance between two layers of insulating low-e  glass is generally 8 
High performance insulating low-e glass is different from ordinary insulating glass. In addition to sealing dry air in the middle of two layers of glass, a special metal film with good thermal performance is coated on the side of the middle air layer of the outer glass.

Introduction of Thermal insulating glass

Founded in 2000, Linqu Sanjing Glass Technology Co., Ltd. is specialist for architectural energy efficient glass. The company located in the middle of Shandong Province of China, covering an area of more than 100000 square meters, with 200 staff.  
Utilizing the most advanced technologies, state of the art equipment and control system, Sanjing Co. , Ltd. provides high quality products, such as Low-E glass, coated glass, insulating glass, tempered glass, laminated glass, tinted glass. ultra white glass,fire-proof glass glazed glass and other related architectural glass. 

Advantages of Thermal insulating glass

Low emissivity glass, also known as low emissivity glass, is a type of glass that is coated to make doors and windows more energy efficient. Originally designed to maintain infrared light exposure in cold climates, it is now a cost-effective option that works in many regions. Low E glass is colorless and ultra-thin (thinner than a strand of hair!), with a non-toxic coating that minimizes UV penetration. Low-E glazing can greatly improve lighting while reducing heating and cooling costs.

  1. We have our own Low-Emissivity production line, we can customize and process Low-E glass according to customer needs.
  2. Mature Low-Emissivity production process, there is no color difference in different batches of glass, which greatly reduces customer after-sales costs.
  3. Our the best quality of fire resistant glass can keep 3 hours not broken in the fire.


Advantages of Thermal insulating glass

Sanjing Low-emissivity Glass, also known as Low-E glass, refers to flat glass coated with one or more coating layers with extremely low surface emissivity. The coating process is usually vacuum magnetron sputtering. It has low thermal conductivity and high light transmittance, ensuring visible light transmittance and reducing light pollution based on prevention of heat losses.

The single silver film layer is composed of 5 layers of film, wherein the functional layer is silver in the middle layer, and the first layer film contacting the glass is a metal oxide film, which functions to reduce the reflectance of silver, increase the transmittance and produce a reflective color. 

Advantages of Thermal insulating glass

Sanjing DOUBLE SILVER LOW-E GLASS features a clear, color-neutral appearance that can be combined in simulating glass units (IGUs) with an outboard lite of tinted or reflective tinted glass to increase aesthetic and performance options. 

Sanjing TRIPLE SILVER LOW-E GLASS with its transparent, color-neutral aesthetic and unprecedented solar control and visible light transmittance characteristics, some Series (WT 72/WTB 70 WTB58) can help strike the right balance between form and function.
