Natural smoke and heat ventilation vents (NSHEV)

From 31 August 2006, it has been a legal requirement to test and evaluate the functionality of complete units, rather than

simply single components, such as drives.
Fieger reacted to these new requirements by introducing "FLW SmoTec" to its existing FLW product range. This system is a

certified NSHEV available in a variety of sizes and with different drives. The large free area of opening, combined with

the short operating time, make Fieger louvre windows particularly effective for venting smoke and hot gas caused by fire.
