The standard method of building walls for homes, offices, and other buildings is to use brick, stone or concrete. The method of construction is to bring all the materials to the site and build the wall with them. This requires the founding slab on which the wall will rest to be completed and to have the required strength before any work on the wall is commenced. Following this sequence leads to considerable delay.

Wall panel systems, in which walls are built into ready to assemble panels off-site in a factory and under controlled conditions, can help to cut down the time to complete a building. These panels can be made of many materials and have the desired finish on them. They can also have the required utilities like power and water integrated into them. A typical wall panel will have a framework of the required thickness, typically of timber, though the use of other things, like light-weight aluminum or steel, is not unknown. The facing on either side of the frame can be of wood, metal or PVC and with the finish desired. The cavities in the wall panel can also be filled with insulation material, that will help in not only conserving energy but also make the wall panels relatively soundproof.

Typically, wall panel systems are made in sizes that are easy to manage and maneuver. They can be lengths of five feet to twelve feet and of the required floor to ceiling height. The wall panels will have doors and windows and any other openings already built into them, and may even come complete with the windows and doors already fixed in position. Every panel will be clearly marked and identified and will have its own position in any sequence of assembly, that the manufacturers will also provide.

It is important that you provide the maker of the wall panels with detailed drawings of the structure that you are planning to build. They will then advise you of the support structure that you need to create that will take in the assembly of the panels that will make the walls of your building. They can also create walls for the exterior, as well as the interiors of the building. Do this planning before you start any work on the structure so that any needs that they may have, are taken care of. It is also important that extreme care is taken to ensure that the dimensions of your support structure are exactly as needed, otherwise, you may find that you have gaps or be required to be chiseled for the panels to fit in. External walls may require sealants to all their sides before they are fixed so that the structure remains waterproof.
