IDELCO AGRO+ ceilings in farm buildings: planning long boards and their joints

Mark the exposed face on the ceiling layout. AGRO+ has a lightly embossed 50 µm aluminium facing. The face towards the room is painted white, with natural aluminium on the reverse. Marking the orientation is especially helpful when trimming pieces at the gable wall.

Declared thermal conductivity for AGRO+ is 0.023 W/(m·K). The declared thermal resistance of the 100 mm board is 4.30 m²K/W. Include temperatures on both sides of the ceiling and the other layers of the assembly in the thermal assessment.

In a livestock building, both occupancy and washing introduce moisture. Identify how it will be removed and how the ceiling meets the outside wall. Check the cleaning agent for compatibility with the paint and joint profiles before use.

Specify each row length after measuring between finished surfaces. Allow for the perimeter profile and installation clearances. Confirm whether lengths up to 13 m are available for the selected thickness before booking transport.

Support spacing and fixing details come from the design. Transfer support lines and board joint positions separately to the fabrication plan. A long board can run over several supports without a transverse joint in each bay.

The AGRO+ sheet lists square edges, step rebates and a rebate with a saw cut for a white installation profile. Assign an edge type to each item on the schedule. On the end-of-row detail, identify the factory edge and the edge to be cut on site.

Try the joint on two short pieces before completing the first row. From floor level, inspect the joint line and the uniformity of the white finish. From the working platform, check profile engagement and the facing along its edge.

IDELCO distinguishes product reaction-to-fire class D-s2,d0 from B-s2,d0 for the stated application with a corner profile. The designer should check whether the proposed ends and joints meet the conditions of the second classification.

If the ceiling forms a fire compartment boundary, identify requirements for the complete assembly, including ducts and openings. The classes quoted describe reaction to fire. Required fire resistance must be demonstrated for the documented assembly.

Give each board a row number, length, thickness and edge type. Base the unloading sequence on access to the installation bays. A board needed just inside the gate should remain accessible even after the next bundle has been unloaded outside.

Measure intermediate profiles, perimeter profiles and service penetrations separately. When planning lifts, allow for the working height and the handling support agreed for each board length and weight.

Where a wide entrance leads to a narrow right-angle turn, trace both board ends on a dimensioned plan. If the board will not clear the turn, compare an alternative lifting point with splitting the row at a designed support before fabrication. In the second option, include the additional joint in the order.
