What is? LOW-E glass ？

LOW-E glass is also called Low emissivity coated glass It has high transmittance to visible light, high reflectivity to infrared ray and ultraviolet ray, good thermal insulation performance and energy-saving effect.

In summer, it can prevent the outdoor solar infrared rays from entering the room, slow down the indoor temperature rise air conditioner Refrigeration consumption; In winter, it can prevent the indoor infrared heat from flowing out through the windows and doors, reduce the loss of indoor heating, and improve the efficiency of indoor heating.

LOW-E The outdoor reflectivity of glass is about 10% - 30%. The outdoor reflectivity is the visible light reflectivity, representing the reflective intensity or dazzling degree. Use LOW-E Glass can not only transmit light, but also improve privacy. You can see outdoors indoors, but not indoors outdoors. Suitable for places with large glass doors and windows: such as living room, bedroom balcony Etc.

How to choose LOW-E glass?

LOW-E Glass Transmittance Generally, there are three specifications: high permeability (more than 70%), medium permeability (50% - 60%) and low permeability (less than 50%). The higher the light transmittance, the lighter the color looks, the better the lighting, and the more transparent it appears; But SHGC（ Solar heat gain coefficient ）The higher the K value (heat transfer coefficient), the worse the thermal insulation performance.

LOW-E glass with different light transmittance can be selected according to your own needs: low floor, weak light You can choose the ones with medium and high transmittance, and the daylighting effect is better; The ones with high floors, sufficient light and large glass area can choose the ones with medium and low permeability, which have better thermal insulation effect.

zero three LOW-E film position?

LOW-E Hollow glass There are four surfaces, in the south and north, due to different living environments, the installation position of the film is also different.

In cold places such as the north, the requirements for glass should be strong heat preservation and high light transmittance. The main function of LOW-E glass is to prevent the escape of heating in winter, and the film is usually placed in Hollow glass Outside of interior panel , i.e From the third side outside.

In the hot summer in the south, the sun shines. LOW-E glass is mainly used for heat insulation and sunscreen. It keeps the cold air blown out by the air conditioner in summer indoors for a long time, so the film layer is placed on the inside of the insulating glass outdoor panel , i.e From the second side outside.
