The New PYROMENT IK90® Typ BD: More Safety and Faster Installation
First Ducting for Electrical Installations to Actively Contain Fire
The new PYROMENT IK90® Typ BD by G+H Isolierung is the first ducting for electrical installations (I-ducting) on the market to actively contain fire. For the first time, it also makes it possible to protect constrictions, and it cuts installation time by up to 80 percent. The system is certified for fire resistance rating I 30 to I 120.
Passive fire protection system with active effect
PYROMENT IK90® Typ BD is made of galvanized steel sheet with a special intumescent coating, forming an insulating barrier, and a top coat. When installed in emergency exits, the system is capable of more than conventional I-ducting, which only protects surroundings from the effects of an electrical cable fire. “In the event of a fire, the intumescent coating swells, immediately preventing the fire from spreading along the ducting,” product engineer Wolfram Adam, expert for preventive fire protection at G+H Isolierung, explained. “This provides operators with a high degree of safety, and if damage does occur, the resulting costs are considerably lower,” Adam further pointed out. Conventional I-ducting with a sheet steel sheath is covered with panels made of mineral wool, calcium silicate or gypsum. While these materials prevent a cable fire from spreading throughout the room, they cannot prevent the ducts from being consumed by fire. Consequently, a risk of considerable damage has existed up to now, as I-ducting is very often laid through several fire sections, resulting in stretches of several hundred meters in some cases.
Constrictions can be protected for the first time
At a thickness of 1.6 to 3.0 millimeters, the new I-ducting is up to 40 millimeters thinner than conventional systems, allowing it to be installed even in difficultly accessed places.This innovative system is fast and easy to install, saving as much as 80 percent of installation time and reducing labor costs considerably. An additional feature facilitating installation is the light weight: at 6.5 to 10.5 kg/m2, this product weighs only a fraction of conventional duct systems.
Thanks to the special material used in the manufacture of PYROMENT IK90® Typ BD, for the first time ducting can be processed and installed dust-free. This makes the system suitable for specialized installations, including hospitals, offices, computer centers, clean rooms and in the food and beverage industry.
