Buying sandwich panels in Wrocław and Lower Silesia: stock, access and delivery

A heated workshop needs a different envelope from a screen around an open store. Where a site is exposed, do not copy the support spacing from a project elsewhere. Use the loads and environmental conditions for the specific location.

List wall and roof panels separately. Specify the core, thickness, lengths, number of pieces and finish. Include the flashings and fixings shown in the design. If substitutions are acceptable, state the limits. ‘White panel for a hall’ leaves too much scope for quotations that cannot be compared.

For repairs, send photographs of the existing cladding and the old product markings. A colour name guarantees neither a matching shade nor a compatible joint. Before buying a replacement section, check the interface. If product data are missing, inspect the junction instead of assuming that equal thickness means a good fit.

Availability means a specific number of panels in the required lengths. Ask for a current batch list, photographs of both faces and a record of damage. For clearance stock, ask how it was stored and whether you can inspect the edges. The top panel is not representative of every panel in the pack.

For collection, agree how staff will make the goods available for inspection. Do not release transport restraints without their agreement and suitable equipment. Record the reservation deadline, quantity and agreed condition in writing before scheduling installation around that batch.

Consider a hypothetical order for 80 m², excluding VAT. At roughly €25.92/m², supplier A’s panels cost about €2,074; with €208 freight the total is €2,282. At about €27.31/m², supplier B’s panels cost €2,185, but freight of just €69 brings the total to €2,254. Figures are rounded and exclude unloading and accessories. The higher panel rate gives the lower delivered price.

A small trailer is not necessarily a saving for long panels. Consider support along the pack, load restraint and permitted transport conditions. Choose a suitable vehicle first: a damaged joint or a second trip can cost more than the saving on materials.

Confirm arrival time, who will receive the load and how it will be unloaded. Match the crane or lifting equipment to the panel weight and length, and keep the only entrance clear. On sites that remain in use, separate the delivery route from routine pedestrian and vehicle traffic.

Prepare a dry, level storage area in accordance with the panel instructions. A low spot in the yard can collect water around the pack. An available delivery slot is useful only if the site is ready to receive and use the material.

File the specification, batch documents and coating details. For phased work, ask about future matching stock without treating availability as guaranteed. If stock is limited, allocate complete wall sections to the batch so that any later change in appearance falls at a planned boundary.

Judge the supplier on the quality of information, conformity of the delivery and completeness of the accessories. Yard size alone says nothing about suitability for your building. Base the order on technical fit, a realistic date and total cost, and keep written confirmation of what was agreed.
