Vacuum glass is created by high-temperature welding a piece of Low-E glass with a piece of float glass, using glass frit as the welding material. The glass frit is of the same material as the glass itself, allowing it to fuse with the glass, ensuring the vacuum remains effective over long-term use. Please refer to the side drawing of the vacuum glass:
Installation Notes:
The adsorbent should always be positioned at the bottom of the wider edge to prevent it from slipping. Therefore, when placing your order, please provide us with the width and height of the vacuum glass so that we can correctly place the adsorbent at the bottom of the wider edge during manufacturing.
The vacuum glass size label is affixed to the white glass surface, which helps to distinguish between the Low-E and white glass.
If you reside in a cold climate, the white glass side of the vacuum glass should face outdoors, while the Low-E side should be on the indoor side. When sunlight hits during the day, the Low-E glass can absorb more heat into the interior. The installation should be as shown in the diagram:
If you live in a hot climate, the white glass side of the vacuum glass should be on the indoor side, with the Low-E side facing outdoors. This way, during the day when sunlight hits, it blocks heat from entering the interior, keeping the room cool. The installation should be as shown in the diagram:
