Fire test on R'BULL Pro 13 thermoreflective thin insulation

Three symbols, three different questions

A reaction to fire classification reads in three parts, and each answers the question a different person is asking. The letter matters to the insurer and to the inspection body. The smoke index matters to the fire service. The droplet index matters to whoever is working under the ceiling.

B, s1, d0, in plain terms

The B means the material makes a limited contribution to a fire: it does not feed it and does not make it grow. The s1 is the lowest smoke opacity level on the scale, the one that leaves a chance of seeing the way out along a corridor. The d0 means no flaming droplet detaches, which is to say the fire stays where it is instead of moving down a floor.

What the classification changes on site

In a dwelling, the regulations do not call for A1 or A2 insulation behind a lining or a plasterboard. In a building open to the public, they call for a facing classified at least A2 in front of the insulation. R'BULL Pro 13 therefore goes behind a board, a mineral panel or an A2 stretch fabric, never bare and never exposed.

Every permitted configuration, building type by building type, is set out on the page devoted to fire regulations. The data sheet and the product characteristics are on the R'BULL Pro 13 page.

What the inspection body will ask for

On a job subject to inspection, the question will not be about the brand of insulation but about the classification report, and about whether that document matches the reference actually delivered. Keeping the roll labels and the delivery note avoids a discussion at the end of the job, when the ceiling is already closed.
