How to check insulation boards before signing for delivery

Bring the final specification rather than the first estimate. A change of thickness after a site measurement may not appear on an old printout.

Make a table with one row per application. Record the product, thickness, facing, edge profile and sales unit. For similar designations, highlight the part of the name that distinguishes them.

Match labels to the order before the crew distributes the material around the building. If a pallet is mixed, count each variant separately. Do not assign the first visible label to the whole pallet.

If the invoice abbreviates a trade name, photograph the full label and the corresponding delivery note line. Resolve a discrepancy with the supplier before the boards disappear under a screed or roof covering.

For example, six rectangular boards measuring 1.20 × 0.60 m have a total geometric area of 4.32 m². This illustrates the arithmetic, not a standard pack size. Use the actual dimensions and count for the boards delivered.

If the edges overlap, check whether the manufacturer quotes overall dimensions or coverage. The area delivered and the area you can insulate after cutting are different figures.

Photograph torn wrapping in context, then take a closer picture of the exposed corner and facing. Packaging damage warrants inspection; it does not by itself prove the board is damaged or fit for installation.

Set aside boards with missing core material, a detached facing or signs of wetting. Record the number and batch reference if available. Keep them separate from boards released for installation.

Mark separate storage spaces for roof, wall and floor boards, respecting the storage instructions. Keep labels accessible even after the next pallet is placed. This reduces handling and the risk of edge damage.

Allocate the accepted pack count to each stage. If two crews draw boards from the same batch, record each issue as it happens. Otherwise a shortage later can look like a short delivery.

Instead of writing only “shortage”, enter the order line, the quantity in question and the amount accepted without comment. Match photographs to a specific pack so the supplier knows whether the issue is condition, quantity or identification.

Keep the agreed findings and any later replacement note. When the work is finished, the records will identify the material actually installed even if the first delivery differed from the final accepted supply.
