About This Product

Firelight is made of ultra-heat-resistant crystallized glass that has a coefficient of thermal expansion of almost zero, so it is resistant to thermal shock and will not break even when heated to 800℃ and poured cold water on it. This is the only glass for specified fire protection equipment that will not be destroyed by the high heat during a fire or the rapid cooling caused by water spray during fire extinguishing operations. It has been used in fire experiments by the Tokyo Fire Department, and its high fire protection performance has been proven, including compliance with American UL standards.

■Firelight PlusⓇ3D

This is heat-resistant glass with an anti-reflection coating for projection room windows, developed in response to the shift to 3D movies. With the shift to 3D movies, projection room windows will also need glass with high transmittance. Firelight® 3D, which has a high-performance anti-reflection coating on both sides, is a certified fire prevention equipment product that has low reflectance and high transmittance. Features

■Highly resistant to thermal shock

The only fire-resistant glass that will not break even when heated to 800℃ and then poured ice water on it is Firelight, which is made of ultra-heat-resistant crystallized glass with almost zero thermal expansion.

■Clear visibility without a net

Clear visibility almost equivalent to regular window glass. Demarcate fire zones with firelights to ensure familiar evacuation routes and visibility.

■No risk of natural damage

Heat-resistant tempered glass has the problem of breaking unexpectedly even when no external force is applied to it, but Firelight is a glass that does not have to worry about this.

■Research on the behavior of fireproof glass components under actual fire heating conditions

Materials for observing and measuring how fireproof glass components behave (occurrence of breakage, etc.) under conditions similar to actual fires, and how these components behave in response to water spray. This was a joint research project conducted by the Fire Research Institute, the University of Tokyo, ERS Co., Ltd., and Nippon Electric Glass Co., Ltd., with the aim of obtaining the following.

■Experiment method

Fireproof glass measuring 1.22 m x 1.93 m was attached to the frame material in an experimental section measuring 4 m x 4 m and with a ceiling height of 2.3 m. The heating specifications used a two-tier stack of No. 2 cribs as a simulated fire source, and ensured the temperature in the upper part of the compartment at around 700℃ for 15 minutes. Then, when the unheated side of the glass reaches its maximum temperature (approximately 470°C), a water sphere made of polyethylene film (300 cc to 930 cc of water) is made to collide with a predetermined position from a height of 50 cm.

■Experiment results

Firelight showed no change at all even after heating and being hit by a water ball, which simulates an actual fire. The heat-resistant tempered glass broke into small pieces and fell off due to the temperature difference during heating and the collision with the water balls, causing a large fire to erupt.
