Greenhouse building materials tempered glass is a multi-glass combination consisting of two or more panes enclosing a hermetically-sealed air space. The sheets are connected by an aluminum spacer with the desiccant inside, and the whole unit is hermetically assembled by a double sealant (butyl, ply-solitude, silicon, etc.). the function will be enhanced if fill the inert air space with inert glass.

Greenhouse building materials tempered glass is distortion-free, precision flat, and transparent glass. It is made of molten glass, which flows through tweel to tin bath and then to lehr. While floating through the molten tin, the glass under the works of gravity and surface tension becomes smooth and flat at both sides. Greenhouse building materials tempered glass is made by top quality float glass, sheet glass, patterned glass. By cutting to the standard sizes and polishing the two long side edges as the flat or round shape, which will protect figures from hurting, also supply a modern performance in the application.

Greenhouse building materials tempered glass is formed as a sandwich of 2 sheets of glass which are bonded together with a transparent or tinted PVB interlayer under heat and pressure. laminated glass is made by good quality adhesive interlayer and advanced bond technology. Usage for Door, window, curtain wall, ceiling, floor, partition wall, roof daylighting, show window of the shop, and roof window of the factory building. There is an extensive application in-vehicle, steamer, bank, jeweler’s shop, villa, etc.

Greenhouse building materials tempered glass can be 3, 4, 5, 6, 8, 10, 12 mm thick sheet glass, the air layer thickness can be 6, 9, 12 mm interval. 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.

Features of greenhouse building materials tempered glass

1. 5 times harder than ordinary float glass, stronger resistance to thermal breakage than annealed or heat strengthened glass.
2. Once breakage occurs, the glass disintegrates into small cubical fragments, which are relatively harmless to the human body.
3. It withstands abrupt temperature change of 220 Centigrade.
4. Sizes are produced as per customer request. Once tempered, it cannot be cut down.

Production Process of greenhouse building materials tempered glass

greenhouse building materials tempered glass is produced by heating annealed glass in a furnace to 620°C. Progressing from the furnace, the glass is rapidly cooled with jets of cold air, inducing compressive stresses to the surface while the center remains tensile.
