After an impact at a loading bay, it is easy to order a panel of the same thickness and a similar colour. The harder part is finding one that joins the adjacent panels and can be installed beside a working bay. Start by establishing the extent of the damage and identifying the existing system. Collect photographs, cover width, joint details and information about access to the fixings. An inspection will help the contractor decide whether a skin repair is sufficient or a whole wall section needs replacing.

A sandwich panel layout connects the building's geometry with the schedule of pieces to be ordered. It should show more than a wall or roof area: panel divisions, their relationship to supports and openings, and references to construction details also matter. Multiplying length by height does not produce a manufacturing schedule. This guide organises the drawing workflow: establish reference points, identify pieces, distinguish building dimensions from order lengths and record changes. Its focus is information passed between designer, installer and supplier. It does not prescribe universal support spacing or installation clearances. Those values must come from the solution developed for the particular building.

Services in a house with a sandwich panel envelope should be planned alongside room layouts and penetrations through the walls and roof. Later drilling may conflict with the structure, airtightness or finishes. A coordinated plan needs to cover routes, equipment, supports and maintenance access. This guide explains what to give designers and contractors before walls are closed. It concerns coordination, not do-it-yourself electrical, ventilation or fire-protection design. It specifies neither opening diameters nor anchor types. Instead, it shows why a socket, cabinet or appliance position must be considered within the complete wall arrangement. The envelope installer should know the agreed routes and fixing positions before work that modifies the panels begins.

A cold room is a large insulated chamber, but its performance depends on the details. The walls, ceiling, floor and doors must limit heat and moisture ingress. PIR sandwich panels make it easier to build the envelope; they do not replace refrigeration equipment or a properly designed floor. In a freezer room, sealed joints and protection for components exposed to sustained low temperatures are particularly important. Chilled and frozen storage do not call for identical enclosures: operating temperatures differ, as do the consequences of moisture ingress. Before selecting panel thickness, tell the designer what goods will be stored, their temperature on arrival and how often the doors will open.

Sandwich panels can form the walls and, in some designs, the roof of an indoor ice rink. They limit heat transfer and make it possible to enclose a large structure quickly. An ice rink poses different challenges from a warehouse: humidity, the risk of condensation and spectator comfort all matter. The envelope therefore needs to be designed together with the structure, refrigeration, ventilation and fire protection. The primary structure must span the rink and keep the space above the ice clear. Sandwich panels enclose the building and transfer loads to their supports; they do not replace the main girders. Coordinating the panel layout with the frame and façade divisions allows large panels to be installed without unplanned cutting on site.

The fixings for a photovoltaic array must suit the specific roof and the loads it will carry. Metal tile roofing, trapezoidal sheets and sandwich panels each require different details. Trace the load path from the modules to the building structure. Watertightness and protection of the coating matter just as much as load capacity. You cannot choose a suitable mounting kit by looking at the covering alone. Identify the roof type, condition, thickness, support spacing and substrate. Include structural drawings and details of past alterations. On older roofs, also check the existing fixings and look for corrosion. Room for modules does not necessarily mean the roof has spare load capacity.
