Fire test on R'BULL Pro 13 reflective thin insulation

The path a fire follows through a house

A fire that starts in a room looks for the top. It finds the ceiling, then the void above it, and that void often runs the length of the floor with nothing to stop it. That is where a contained incident becomes a total loss, and it is exactly where the insulation sits.

Why the test covers the whole complex

R'BULL Pro 13 combines a bubble polyethylene foam with two faces of protected aluminium. Testing the aluminium alone would mean nothing, it does not burn. Testing the foam alone would mean no more, it is never fitted bare. What faces the flame is the assembly as it arrives on site.

What is asked of a product fitted under a roof

Not to feed the fire, not to fill the floor with smoke, not to drop flaming droplets into the void below. Those three expectations map exactly onto the three parts of the B-s1,d0 classification obtained under EN 13501-1. That is no accident: the standard was written from the way real fires behave, not from an abstract scale.

The permitted installation configurations by building type are set out on our fire regulations page. The full product characteristics are on the R'BULL Pro 13 page.

The point an unused loft makes critical

Nobody ever goes up into an unused loft. A fault is not seen, a smell is not noticed, the beginning of a failure goes unremarked for years. That is why we favour materials that do not degrade on their own: high density polyethylene and pure aluminium do not age the way organic binders do.
