Livestock suspended ceiling — termPIR® AGRO AL CEIL

When to use this system

Suspended ceiling in a livestock building — when the roof is not made of sandwich panels (e.g. timber truss structure, hall with trapezoidal steel roof sheet without insulation) — and we need to insulate inside and separate the air volume above the animals.

Choose this system when:

• Renovation of an existing building — existing trapezoidal sheet roof without insulation, we add a suspended ceiling 1.5-2 m below the ridge.
• Air volume separation — lower zone (animals) warm and insulated, upper zone (attic) cold, ventilated.
• Small heated volume — it is easier to heat 2.5 m of height under the ceiling than 4-5 m up to the ridge.
• B-s2,d0 ceiling requirement — termPIR® AGRO AL CEIL has an additional fire classification in the final ceiling application (vs standard AGRO AL in class D).

Installation requirements

• Support structure — galvanised CD/UD profiles fixed to the roof structure (rafters / trusses / purlins). Spacing of main profiles 800-1000 mm.
• Board fixing — combination of bonding + mechanical fasteners:
  • PU adhesive applied perimetrically + spot-bonded on the profiles,
  • self-drilling fasteners through the board into the profile every 400-600 mm, with a PVC washer eliminating the thermal bridge.
• Joint sealing — aluminium tape on all board joints. This is critical — water vapour condensation from barn air (RH > 80%) penetrates through leaks and destroys the insulation within 3-5 years.
• Service penetrations (ventilation, lighting, monitoring) — with EPDM sealing collars + neutral frost-resistant silicone. Every leak = thermal bridge + condensation.
• Ventilation chimney — the ceiling must allow air exchange (opening with controlled damper or a continuous ridge slot).

Volumetric architecture

Roof (cold, ventilated)
─────────────────────────  ← original roof structure
        ↑ exchanged air, dry, cold
─────────────────────────  ← suspended ceiling termPIR® AGRO AL CEIL
        ↑ heated air, humid, with NH3
   animals + bedding + manure
─────────────────────────  ← floor slab

The ceiling separates the animal zone (warm, humid, aggressive with NH3) from the roof space (cold, dry). The Al CEIL foil facing the animals is:

• gas-tight — NH3 does not penetrate into the insulation,
• washable — pressure washing during building sanitisation procedures,
• B-s2,d0 — meets the fire requirement for heated livestock buildings.
