1. Don't install curtains too early, in order to avoid damage from site work.
2. Ensure rollers are perfectly horizontal - otherwise curtain fabric will drift.
3. Avoid carrying out full commissioning before final power is switched on.
4. Measure the clear height under the curtain and the designed drop of the curtain prior to manufacture.
5. Ensure the space above the curtain is stopped with fire/temperature rated materials with an identical rating as the curtain itself. If ducts pass over the top, these should either have dampers to maintain fire resistance, or be fire rated.
6. Ensure the control system has dual supplies.
7. Check that the gaps between curtains are not excessive – the maximum gaps are specified in EN12101-1.
8. Use a curtain bottom bar that is suitable for the type of ceiling into which the curtain is installed. Gypsum type ceilings can be subtly uneven and these imperfections will show up with a straight bottom bar, therefore use a recessed or self-levelling bottom bar in this instance.
9. Likewise, floors can be uneven, so when using fire curtains to stop fire spread, make sure that the curtain can compensate for uneven floors.
