Partitions let one hall serve several uses by dividing the floor with curtains, folding screens or movable panels instead of walls. Curtains divide sight and warm a zone but stop almost no sound, about 1 dB for a 0.5 kg/m² cloth against about 27 dB for a 2 cm timber panel, so put noisy and quiet uses at opposite ends of the hall and keep every partition clear of the exit routes.
Part of Community Gathering Hall
Partition and divider systems are the movable curtains, screens and panels that subdivide a hall’s open floor into temporary rooms.
Dividers Are For Sight And Warmth, Not For Sound
The gathering-hall guide uses movable screens or curtains in two ways: to partition a heated zone so that only the occupied part of the hall is warmed, and to create a classroom zone while the rest of the hall remains available. Both are visual and thermal uses. Sound passes through a divider unless it has mass, which the mass law shows.
Worked Example: Curtain Against Panel
Inputs: transmission loss TL ≈ 20 × log₁₀(f × m) − 47 dB, with f in hertz and m the surface mass in kg/m² (Sound Isolation Between Units explains the formula and its limits); f = 500 Hz; heavy curtain cloth about 0.5 kg/m² (assumed); timber 500 kg/m³ (assumed).
- Curtain: f × m = 500 × 0.5 = 250; log₁₀ = 2.40; TL = 20 × 2.40 − 47 = 1 dB.
- A 2 cm timber panel: m = 0.02 × 500 = 10 kg/m²; f × m = 5,000; log₁₀ = 3.70; TL = 20 × 3.70 − 47 = 27 dB.
The formula is for an airtight panel and a flimsy curtain does not follow it exactly, but the conclusion is robust: a curtain gives a visual and slightly draught-reducing boundary, and almost no acoustic one.
What You Need
- A track, rope or beam at roof height to hang curtains from
- Heavy cloth or woven hangings, sized to the zone
- Screens or panels that stand firmly and fold flat
- A store for dividers when the hall is open
Method
Step 1: Decide the zones for each layout (school, medical, meeting) on the plan.
Step 2: Fix the track along lines that leave aisles of clear width to every exit and between zones.
Step 3: Hang curtains to the floor or near it, so the zone is private and draughts are reduced.
Step 4: Separate noisy from quiet uses. Put the kitchen and dining at one end and the classroom and medical zone at the other, with the small room and the store as a buffer.
Step 5: Fasten free-standing screens so that a child or a crowd cannot tip them.
Common Mistakes
- Expecting a curtain to give a private conversation or a quiet class.
- Partitions across the way to an exit.
- Heavy curtains hung near the hearth or a lamp.
Safety
Curtains burn and screens block
Textile hangings are fuel; keep them well clear of any hearth, flue, stove or lamp (the fire guide keeps a wood stove at least 40 cm from combustible walls, and a hanging is more flammable than a wall). Every zone made by a partition must still have a route out that a person can follow without lifting a curtain or moving furniture (Fire Prevention in Settlements).
