Smoke
and curtain walls
A smoke barrier is constructed to
prevent or restrict the spread of smoke
and fire within a the building. It is
normally tested to meet the requirement
of BS 7346: Part 3: 1990 which requires the barrier to withstand a fire temperature of 600OC
for a minimum of 30 minutes. A SUPALUX® Smoke Barrier system provides up to
30 minutes fire resistance and is
commonly used in projects throughout Asia.
