What evidence will building control ask for on fire-rated glazing?

Building control will usually want the classification report or certificate for each glazed system, any assessments relied on, confirmation that installed pane sizes and details fall within that evidence, and installation records such as photographs of seals and fire-stopping before they are covered.

Before work starts

Provide product evidence with the design submission, especially for higher-risk buildings in England where the Building Safety Regulator reviews designs before construction.

During installation

Photograph beads, seals, fixings and fire-stopping as they are fitted. Once closed up they are hard to verify.

At completion

Hand over a schedule of glazed elements with locations, classifications, glass marks and evidence references. This also feeds the building's fire safety information.
