Damage from fires can be devastating to your business & life. Protecting your residence & business from fire, winning the most valuable time for people to escape & rescue are the core functions of TENA fire proof glass, windows and doors.



  TENA high-impact Na-K fire-resistant single glass sheet

Superior property

of fire-resistance

It is able to withstand the harsh test of fire, around 1000 °C flame, for max.180 minutes without broken and stop the spreading of flame and smoke. It can protect people & high-valued articles temporarily from the threat of fire and win the most precious period for people to escape, move away the high-valued articles and extinguish the fire. It solved the problem of poor fire-resistance of ordinary glass sheets in buildings. As illustrated in the picture below.


Scientific principle

By special high-tech chemical & physical processing in a series of sophisticated machines, Na+ ions on surface of the glass sheet exchange with K+ions in heated bathing liquid (melted chemicals in scientific formula) and form an invisible special surface cover with much stronger stress and higher fire-resistant properties than those of ordinary flat glass sheets. 

Comparing fire-resistant tests on three types of glass sheet (the same thickness)

- The tested common glass sheet lost its integrity (broken by fire) of fire-resistance when the temperature reached 230℃ or so after the test began about 2 minutes

- The tested physically tempered and processed glass sheet lost its integrity of fire-resistance when the temperature reached 700℃ or so after the test began about 60~120 minutes

- The tested TENA high-impact Na-K fire-resistant glass sheet can keep its integrity of fire-resistance when the temperature rise above 1000℃ after the test began about 90~180 minutes

TENA Na-K fire-resistant single glass sheets

VS industrial rivals’ products

-Most rivals’ fire-resistant single glass sheets: Only a thin layer of fire-resistant liquid is applied on their surface and dried into a film in factory processing. The dried film usually age & disappear gradually over a short period in a few months and lose the property of fire-resistance.

-TENA high-impact Na-K fire-resistant single glass sheets: The invisible special surface cover, with much stronger stress and much higher fire-resistant properties, has actually been formed inside the glass sheet itself. Thus its fire-resistant property will never go away in its lifetime.

High-impact performance

It can withstand the vertical hit by a 1.015 Kg steel ball falling freely from 1.25 meter height, and separately, the side hit by a 45 Kg ball of lead bullets from 1.2 meter height, without broken. Its physical strength is 5~10 times higher than that of ordinary flat glass sheets. 

Excellent weather-resistance

It can stand the long-term exposure to UV light and sunlight without any change of color or transparency.

5mm,1.50 hrs C-type single fire proof glass-Test Report

C-type 5mm thick single fire proof glass w/ integrity of fire-resistant not less than 1.50 hrs (Model: DFB-05-C1.50) in line with China National Standard (GB15763.1-2009, Safety glazing materials in building-Part 1: Fire-resistant glass) . The test report was issued by <China National Center for Quality Supervision & Test of Fixed Fire-fighting Systems and Fire-resisting Building Component>.

TENA testing equipment on fire proof glass


TENA Super large machine for making Na-K fire proof glass sheets. 

The machine is the most advanced in China speicial glass industry. Its products are made through

a series of complicated chemical exchange of Na & K ions between the surface of glass sheets and

the bathing checimals in the machine. TENA Na-K fireproof glass sheets are finally available with

superior features of fire proof and high-impact physical performances.


TENA Group owns 14 national patents focusing on innovations with the honor of

<Certificate of High & New Tech Enterprise> granted by the government.


TENA patent:  A kind of device to inject fire-resistant gum into inner space of insulated fire-resistant glass

TENA <Certificate of High & New Tech Enterprise> granted by the government
