Start with the exact product identity

Name, manufacturer, version, thickness and any surface treatment must match. A classification for an uncoated board does not automatically apply to every additional colour, facing or bonded combination. Also check the issue date and validity reference of the documents.

A European Technical Assessment describes the assessed performance and conditions of use of a product. It is not a universal clearance for every conceivable roof application. EOTA explains the purpose and procedure of the ETA. [1]

Sort evidence by its task

The product data sheet provides dimensions, mass and handling, among other things. The classification report describes the class determined and its field of application. A system assessment assigns layers, fixing and substrate. The project documents show how these become your roof.

For example, the technical assessment contains different annexes for different clad constructions. The title "fire protection board" alone does not say which annex fits a project. [2]

Read the tested build-up in full

In a fire report, the result and the photo are not the only points of interest. What matters are fire side, burner or fire source, test duration, insulation, membrane, number of layers, joints and fixing. In PV studies, module arrangement and distance to the roof are added. [3]

Example Efectis: in the published BarrierSheet build-up, two mineral layers sit at different positions around the PIR insulation. Anyone who adopts only the logo or the board thickness overlooks an essential part of the construction. [4]

Describe deviations briefly and constructively

Deviations occur in real projects: a different membrane, a different insulation thickness, special PV feet or an existing waterproofing that is to remain. A good document places the tested and the planned build-up side by side and explains the differences.

This allows the responsible designer, inspector or insurer to assess specifically whether a transfer is possible or additional evidence is required. That is faster than an unsorted collection of certificates with no relation to the roof.

Document the installation too

Photos before layers are closed, delivery notes, fixing grids, repair patches and an acceptance of the details help later with maintenance and damage assessment. Keep contact persons and the last approved drawing revision together.

VlamShield structures project enquiries by roof build-up, area, waterproofing, PV layout and schedule. This allows a recommendation to be related to the specific material and installation situation. The guide to insurer requirements supplements this dossier with the desired protective performance.

Submit the data sheet, classification and roof section together. Mark each departure in the proposed build-up against the corresponding evidence.
