LEPIR II FIRE SAFETY TEST

2018 + 2023 | France | Murogeopietra^® on EPS meets criteria for non-propagation of a flame front. The procedure passed the LEPIR II test, allowing it to clad R+4 buildings up to 2,000 m altitude with joints technique.

After the visual inspection after completing the test, the stone cladding was difficult to remove from the left window jamb and architrave. At the crack created through the thermal shock, it can be noted that in the absence of the panel of rock wool, the underlying EPS insulation has sublimed, whereas the guaranteed solution (Technical Manual section 6.21) has contributed to keeping the layers of adhesive, mesh and stone perfectly anchored to the base via the wall plugs.

TECHNICAL DEEPENING

Quakeproof Test UNI EN 1998-1

2016 | France | Regulation establishes the essential requirements applicable to buildings and civil engineering in an earthquake zone.

1. Wall installation on the machine simulator. 

2. Execution of the 8 phases of the seismic stress test.

3. Wall checked by the technicians on site after the test:

No collapses, detachments or cracks have been observed.

Building planning for quake resistance. Regulation establishes the essential requirements applicable to buildings and civil engineering in an earthquake zone and provides the rules to represent seismic actions and their combining with other actions, in order to safeguard lives in case of earthquake, to limit damages and permit to civil protection’s most important structures to remain safe.

FIRE AND SMOKE CLASS
UNI EN 13823

2016 | France | CSTB Test SBI (Single Burning Item) /
Determining material’s fire and smoke classes. EN 1382

Herewith we report soma data regarding the fire test made on wall covering Murogeopietra^® installed on 160 mm external thermal EPS insulation; this test confirms murogeopietra as a not flammable material and attests a complete lack of toxic smoke development.

This means that Murogeopietra^® protects the underlying insulation against heat, so that sublimation is avoided during the time necessary for evacuation.

MANY LABORATORY TESTS
CLIMATIC CHAMBER

2014 | Italy | ACCELERATED AGEING on exterior thermal insulation.

We were greatly concerned about the possible presence of water in the structure due to external weathering or the passage of vapour and its disposal. A test performed at Milan Polytechnic confirmed the validity of the system and the corrections made to the ingredients used. 

At the same time, we tested the same insulation cladding coated with cut natural stone, and we found that it was impossible to use it, just as we had supposed. The non-modifiable technical values, such as permeability to vapour and weight, significantly affect the efficiency of insulation.

FIRE TEST

2010 | Austria | FIRE TEST
IBS Institut für Brandschutztechnik und Sicherheitsforschung GmbH

Great importance was given to safety at the design stage. In Europe there are specific regulations governing escape routes in case of fire. In the case in point, our Murogeopietra® cladding system coupled with the EPS insulation coating, which is notoriously sensitive to fire, was not supposed to collapse and obstruct the escape routes during evacuation of the building, which was established in 30 minutes under the action of a flame hitting the escape route directly at 900 C°. 

The test was successful and the insulation (on the whole height of 6 metres) did not collapse at all thanks to the stone veneer’s high thermal inertia, which protected it for the entire time required.
