Sandwich-panel prices: comparing square metres, individual panels and complete orders

Assume two material rates: PLN 200 excluding VAT/m² for a selected 60 mm panel and PLN 270 excluding VAT/m² for a 120 mm version. At an assumed VAT rate of 23%, these become PLN 246 and PLN 332.10 including VAT/m². They are calculation inputs, not a current offer or an average market price. Replace them with prices for the required configuration before purchasing.

Alongside the rate, record the core, both facings, coatings and colour. Include lengths and panel counts. Without these details, the amount has limited value: the same thickness can describe different constructions and uses. Also check quotation validity, availability and delivery cost. Together, these details provide the basis for a budget.

A decorative embossed panel need not have the same price or application rules as a plain wall panel. Two roof panels may also require different pitches and support spacings. Compare products suitable for the same job. If one requires structural changes, include their cost before assessing the saving.

An omitted price for the required variant does not justify inserting the rate for another product. Obtain a separate quotation. Using the price of an arbitrary panel creates a falsely precise estimate. The discrepancy may only emerge when ordering, after installation dates and equipment hire have already been arranged.

A panel with 1 m cover width and 4 m length has an area of 4 m². At the assumed PLN 200 excluding VAT/m², one panel costs PLN 800 excluding VAT, or PLN 984 including the assumed 23% VAT. At PLN 270 excluding VAT/m², the figures are PLN 1,080 excluding VAT and PLN 1,328.40 including VAT. The area is identical; the material rates differ.

These calculations exclude flashings and installation. A different module changes the area: a 4 m panel with 1.1 m cover width covers 4.4 m² and costs PLN 880 excluding VAT at PLN 200/m². Four metres of length do not always mean four square metres. Check the units in every quotation line.

Core type and thickness matter, along with facings, coatings, colour and profiling. Panel lengths, batch size and production date can change the price. Do not assume one rate applies to all panels. Even similar-looking surfaces can have different protective systems and service conditions.

State the required performance in your enquiry. A lower U-value reduces heat transfer, but panel price alone does not determine the building’s economics. Load-bearing capacity and fire requirements need separate checks. Replacing a model to reduce cost requires an assessment against the design and may also change the necessary fixings and flashings.

Check whether the price includes preparation of lengths, packaging and freight. Agree the unloading method. Add flashings, screws, washers, tapes and sealants. Installation and the supporting frame are separate budget items. Delivering panels to site does not by itself provide a complete building.

Long panels need suitable transport, storage space and lifting arrangements. Meeting these conditions can require additional equipment and labour. Fixed costs are particularly significant on small projects. Compare totals for identical scopes: the same material price can produce different final costs.

A free quote should state its date and validity period. Establish whether a specific batch is reserved and whether later collection changes the price. A promotion may cover only a specified quantity. Check the terms for ordering missing pieces later; a small top-up need not receive the same conditions as the initial large delivery.

Keep the quotation on which the order is based, including validity, full specification and transport arrangements. When a discount is offered, compare the final amount. Do not add several discount percentages without knowing how they are applied. The relevant figure is the price of the particular package, not simply the advertised percentage reduction.

For 50 m² of purchased material at an assumed PLN 200 excluding VAT/m², the panel subtotal is PLN 10,000 excluding VAT, or PLN 12,300 including the assumed 23% VAT. This calculation adds no allowance for waste, flashings, freight or installation labour. State whether the 50 m² already includes a reserve. If longer pieces must be ordered, count their full purchased area so that the initial budget and final quotation cover the same scope.

No. That figure is used solely as a calculation example here. Actual rates depend on the version, quantity and delivery conditions.

Not always. You need a quotation for the full order stating validity, quantity, freight and unloading costs.
