Heat Resistant Transparent Ceramic Glass 800 Degree 4mm for  Glass 

Advantages of Heat Resistant Glass

The main advantage of Heat Resistant glass is that it helps in insulation by reducing the heat gain and heat loss.    Adding multiple layers of glass with gas infill further protects the windows and building from heat loss.

Another advantage of Heat Resistant glass is that it increases the energy efficiency in buildings.    The reduced heat transfer lowers the electrical power consumption required for heating or cooling of the space.    This drastically cuts down the electrical bills especially in areas subjected to extreme heat or cold.    The use of low-e glass and reflective coatings can further improve the efficiency of the windows by further limiting the heat transfer.

Heat Resistant glass also helps in sound insulation and improves the acoustics of the place.      The inert gas present in between the two panes of glass does not allow noise to pass through and acts as a barrier  between the interiors of the building and the noise that is present outside the building .

The factory mainly produces       


Borosilicate 3.3 heat-resistant glass is widely used in household appliances, electronics, instrumentation, optics, aerospace and other fields.

Borosilicate 3.3 heat-resistant glass has good thermal properties, mechanical properties, optical properties and ultra-high chemical stability.   The visible light transmittance is 92%, and the high light transmittance in the near-infrared and ultraviolet bands exceeds 90%.   The sign of fluorescence is far lower than that of soda lime glass.

1)Water resistance (International Organization for Standardization 719): Grade A

2)Acid resistance (International Organization for Standardization 195): Grade A

3)Alkali resistance (International Organization for Standardization 695): Grade B


The thickness of the glass ranges from 2.5mm to 15mm, and the maximum size can reach 4800mm×2440mm.

Q:Ventilation duct fan outsourcing fireproof material specifically what
8.5.6 Ventilation, air conditioning system piping, etc., should be made of non-burning materials, but contact with corrosive media duct and flexible joints, can be made of refractory materials. 8.5.7 Insulation materials, silencers and adhesives for pipes and equipment shall be non-combustible materials or refractory materials. Through the firewall and deformation of the duct on both sides of the 2.00m should be used within the scope of non-combustion materials and binders. 8.5.8 When the electric heater is installed in the duct, the fan shall be interlocked with the electric heater. Electric heater before and after the 800mm within the duct and through the fire source and other parts of the pipeline through the fire, must use non-combustible insulation materials fire retardant coating, fire sealant
Q:Height greater than 60m residential building construction, when the use of B1-class insulation material, every few layers to set the level of fire isolation belt?
(A) residential construction should meet the following requirements: 1, height greater than or equal to 100m of the building, the insulation of the combustion properties of the material should be a bile to pick up the state. 2, the height is greater than or equal to 60m less than 100m of the building, the insulation properties of the combustion performance should not be lower than B2. When using B2 insulation material, each layer should be set to a level of fire isolation zone. 3, the height is greater than or equal to 24m less than 60m of the building, the insulation of the combustion performance should not be lower than B2. When using B2 insulation material, each two layers should be set to the level of fire isolation zone. 4, the height of less than 24m of the building, the insulation properties of the combustion performance should not be lower than the B2 level. Among them, when the use of B2-class insulation material, the three should be set up a horizontal fire isolation zone.
Q:What is the meaning of the plastic raw material fire rating HB?
HB level is not the meaning of fire.
Q:Extruded board fire B1, B2 grade material how to distinguish
Fire level and density does not matter, with the lighter point can not fully explain the problem, b1 level to compound gb8624b1 level
Q:A1 grade external wall insulation materials which
Inorganic materials: glass wool, rock wool, foam glass and so on. Organic class, only the phenolic foam composite insulation board.
Q:If not expensive to buy one of the best, but OKorder did not find. Because I have some important documents, documents, money, worry about living somewhere a day of fire. In case, I would like to put these important objects inside the bag can be fire. Not much of a thing, a folder size of the bag is enough. What materials can be used to make one way? Can also wrap the line, but can often open, not like the tape that ridge set up the plateau dry chop suck raft by the sample sealed. Thank you. More
I can do you can give me a message that we simply talk about my product at 3000 degrees high temperature is no problem, and carry with no problems, heavy ridge set up the plateau dry chop sucking raft by the volume is also light, easy to keep.
Q:Decorative materials Fireproof paint three degrees What does it mean
Fire paint three degrees, three degrees is three times (times), the general budget above the called. Different fire retardant paint in the construction of the ingot dumplings chubby off the rafters when the request is not the same {to do the budget in accordance with the actual and design}.
Q:Gypsum board with fire performance is it?
Gypsum board is the main component of calcium sulfate, chemical formula CaSO4. Melting point 1450 ℃, the relative density of 2.96, insoluble in water. Its dihydrate CaSO4 ? 2H2O is commonly known as gypsum (or gypsum). Hemihydrate CaSO4 ? 1 / 2H2O called plaster (or gypsum). Gypsum is a mineral, for the monoclinic crystal, was plate or fibrous, there are fine lumps, was light gray, reddish, light yellow or light blue. Gypsum heated to 128 ℃, lost most of the crystal water, into a plaster; 163 ℃ above, all the loss of crystal water. The plaster of the plaster is mixed with the plastic, but soon hardened to become gypsum. This process releases a lot of heat and swells, so it can be used for casting models and sculptures including gypsum pliers, with fire resistance.
Q:Conventional gypsum board fire rating is several levels?
B1 level, but in accordance with the provisions of the national standard gypsum board and light steel keel can be used together when the A-level materials, Ordinary paper gypsum board detection level for the B1 level
Q:Does the ceiling need to brush fire paint?
The use of the roof is not flammable materials, in accordance with the construction of Gong Yu Gui Yi Yi see the color of the design of fire code is not brush fire retardant paint, but the master's roof must be painted fire retardant paint, a fire 1.5h, two fire 1h. If it is needed with wooden keel
