The use of glass in a building allows for more daylight. Natural daylight offers a healthy and serene climate. The users of the building can therefore enjoy more comfort and wellbeing. Essentials such as natural light and heat can be harnessed and optimized by glass all year long.
Despite preconceived ideas, fireproof constructions do not have to be bulky and heavy. We were the first to have turned these into lightweight, glazed and fully transparent constructions. We integrate fireproof glass into metallic structures that protect the building from fire. We have invested in fire testing for more than 25 years, and this allows us to keep pushing the protection limits further.
We have developed a unique system for creating fully glazed fire-resistant constructions. All systems meet the very strict Belgian norm NBN 713.020 (often referred to as RF or CF). This standard is referred to by the European Union as EI30, EI60, EI90 and EI120.
The test simulates a fire and studies the reaction of the fireproof elements. A test construction is installed in front of an oven (3m x 3m). The temperature within the oven follows the standardized ISO curve: the temperature of the oven reaches 821°C after 30 minutes and 925°C after 60 minutes. One side of the door faces the oven; the other side is called the public side.
Temperature sensors are fitted to the public side of the test construction. These sensors measure the temperature variations between the ambient temperature in the test lab (for instance 20°C) and the surface temperature on the fireproof element. During the whole test period, the fireproof element must comply with 3 criteria:
