TENA (Model: TN-DFB-08-C2.00) High-impact Na-K Fire Proof 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.

Test Reports/Certifications

Passed test of National Standard <GB15763.1-2009, Safety glazing materials in building-Part 1: Fire-resistant glass>

Applications

External/ internal curtain walls, fire-resistant windows & doors, partitions, atrium, lighting roof, smoke barriers and other locations in buildings. Especially widely applicable to fire-resistant windows & doors, and fire-prevention passageways in medium-to-high end high-rise buildings & public buildings, such as hotel, shopping mall, museum, concert hall, theater, business center, airport, library, university, CBD area, banks, media center, hospital, etc.

Building projects applied

TENA products have been widely used successfully in hundreds of outstanding buildings, such as National Center for the Performing Arts (NCPA) in Beijing, Guangzhou International Finance Centre (IFC), Guangzhou Railway Station, 5-star Sheraton Dameisha Resort Hotel Shenzhen, etc. TENA products are winning the trust of more and more clients.
