When should wall panels be laid horizontally and when vertically?

Mark the edges of openings relative to the cover width. A layout that looks good on an empty wall may create many narrow cut pieces at doors. Shifting the division sometimes reduces waste. However, it should not lead to a change in the position of the opening that worsens the function of the interior or requires an unagreed change to the structure.

It is also worth viewing the façade from the side from which it will most often be seen. A long driveway gives a different perception of the divisions than an entrance right at the corner. This observation helps to decide on the aesthetic variant after checking the technical aspects. It should not, however, lead to hiding necessary joints contrary to the system rules.

In a vertical layout, the panels are usually supported on horizontal structural elements. In a horizontal layout, columns or vertical profiles may serve as supports. The exact scheme must correspond to the design and the tables for the specific product. It is not enough to rotate the panels while leaving the existing frame without verification.

The support widths and fixing locations also matter. Two walls with the same area may have a completely different number of connections. So establish the entire layout before comparing prices. Otherwise, the cheaper material variant may require additional profiles that were not included in the quote.

If one panel does not cover the entire length or height of the field, a designed joint is required. It must provide support, tightness and protection of the ends. In a horizontal layout, such joints may form vertical strips of flashings. Their width and rhythm should be anticipated at the concept stage.

In some concealed-fixing systems, a horizontal layout requires additional joint flashings. One should not assume an identical effect to a vertical arrangement. Data on appearance should go hand in hand with technical detail. A nice visualisation without a joint solution is not a complete wall design.

A vertical panel can match the building height, while a horizontal one can span between columns. Differences in length affect transport and handling. In a narrow yard, manoeuvring a long element is more difficult than on an open site. A heavier mineral wool core additionally requires proper preparation of the equipment.

Do not choose the orientation solely by what can be carried by hand. The lifting method must correspond to the instructions and the working conditions. Determine the installation sequence, the lift access and the storage location. Sometimes a sensible division into fields makes execution easier, but requires more joints. These effects must be assessed together.

The possibility of installing in both directions does not mean identical conditions for every parameter. The fire resistance class of the partition is particularly important. Load-bearing capacity and fixings must also be related to the correct configuration. Data from the vertical arrangement should not be transferred to the horizontal one without verification.

Pay attention to the detailing of corners, the plinth and the junction with the roof. Water should be drained in accordance with the system detail. The panel edge must not be reversed arbitrarily, nor may part of it be removed for ease of assembly. The installation direction and the outer face are determined by the marking and the product documentation.

For a small building with a workshop and a storage area, prepare two elevation drawings. Count the required lengths, the number of joints and flashings. Add the structural changes and the method of positioning the panels. Only variants described in this way are comparable financially. The square metre of the same product alone does not show the difference in execution cost.

Also consider future servicing. Access to flashings and the possibility of replacing a damaged element can be important in the forklift traffic zone. This does not mean that one direction is always easier. The result depends on the connection layout and the surroundings. It is worth recording the reason for the choice so that a later change does not overlook these findings.
