Support spacing does not depend solely on the thickness of the wall sandwich panel. Wind, cladding, core and span arrangement all matter. The fixings must also be checked. A lightweight envelope can transfer considerable suction forces. A ready-made table from another project is therefore not enough. The selection should relate to the specific façade and its load zones. Establish the location, height, dimensions and surroundings of the building. Wind assessment is also influenced by the roof shape and the arrangement of openings. A pavilion on open terrain may behave differently from a similar building in dense development. The load is not chosen solely by the name of the city.

In a livestock building, the panel operates in a different environment than in a dry warehouse. There is moisture, contamination and regular cleaning. A cattle shed, pig house and poultry house do not necessarily require the same variant. Selection begins with the conditions on both sides of the enclosure. Insulation thickness is only one of the decisions. Determine the temperature, humidity and method of ventilation. The type of livestock, stocking density and processes carried out in the building are important. Specify the cleaning agents and the conditions in which they are used. The description “agricultural” does not define the concentration of chemical agents or the frequency of cleaning. Without this information, it is difficult to select the cladding.
