Fireplace glass is colloquially referred to as glass used on fireplaces.

The high-temperature glass installed on the fireplace is both beautiful and energy-saving, which can effectively prevent smoke from entering the room, while also preventing the burning flame from escaping from the door of the fire chamber. The fireplace glass has a relatively high thermal conductivity, which can transfer heat to the interior, while sealing the wall furnace mouth. It can effectively observe the combustion situation and flame size within the furnace door, with significant energy-saving effects.

2、 Characteristics

1. Mechanical characteristics

1. Density( ρ): Approximately 2.6 g/cm3;

2. Modulus of elasticity (E): approximately 93 x 103 MPa;

The test was carried out in accordance with DIN 13316. Apply a tensile or compressive load to a rod shaped test piece to produce a length change. The magnitude of this change depends on the characteristics of the material itself and the magnitude of the load. The elastic modulus describes the relationship between the tensile (compressive) force and the change in material length.

give an example:

Low elastic modulus: highly deformed or deformed under low stress

High elastic modulus: low deformation or deformation only under high stress

Comparison of elastic modulus: rubber 0.05 kN/mm2, aluminum 73 kN/mm2, glass 60/90 kN/mm2

3. Bending strength( σ BB): About 35 MPa (The bending strength test is conducted according to DIN EN 1288 part 5 (R45) standard.)

2. Thermal properties

Average linear thermal expansion coefficient α (20 - 800°C):(0 ± 0.5) x 10-6 /K

3. Chemical properties

1. Acid resistance: DIN 12116 - Minimum grade S3

2. Alkali resistance: according to ISO 695 - minimum grade A2

3. Water resistance: DIN ISO 719-HGB 1

4. Surface changes in use

Glass has good resistance to chemical surface attack. In individual cases or under special circumstances, such as corrosive combustion exhaust gases (acidified substances at high temperatures), changes may occur on the surface of the glass. In such applications, actual testing must be performed before use.


1. Hot pot furnace panels, wave soldering, furnace and fireplace panels.

2. Protective panels for electric heaters, high-performance spotlights, and floor lights.

3. Red UV drying equipment.

4. Such as infrared drying equipment, ultraviolet protection equipment, barbecue plates, laboratory and high-temperature welding masks, safety glass, etc.

5. Wood burning fireplaces, electric fireplaces, real fire fireplaces, and other series.

6. Widely used in gas fireplaces, real fire fireplaces, and other series of products, especially suitable for areas with great temperature differences and strong temperature shocks.
