Major technical progress with the obtaining of two ATEx
A new step that is fully in line with the quality approach in place, ORSOL facings have benefited since July 2021 from an ATEx (Technical Experimental Assessment) case A no. 2926-V1 issued by the CSTB.
This technical assessment aims to evaluate innovative products or processes through the examination of a dossier. This assessment procedure was carried out by a committee of experts coordinated by the CSTB, and concluded with the issuance of an ATEx which attests to the reliability of ORSOL facings and their IDEAPOSE installation process for the supports of shuttered concrete type and RT3 coated with a CS4 coating. This process allows ORSOL to guarantee its products for 10 years (excluding installation) and ensures an optimal aesthetic result over time.
New possibilities beyond the DTU for construction professionals
This ATEx notably offers the possibility of installing ORSOL facings with unfilled joints weighing more than 40 kg/m22 up to a height of 6m, outdoors.
ORSOL facings can therefore be installed in situations not covered by DTU 52.2 (Unified Technical Document), and thus be more easily recommended in the context of calls for tenders for public worksites or those subject to the approval of a control office. This ATEx is thus a real technical recognition which facilitates the approach of architects and promoters, because it confirms that ORSOL facings fully meet the safety and performance standards expected in the field of construction.
A new ATEx in partnership with ZOLPAN
To meet environmental concerns and regulatory requirements in terms of energy performance (RT2012 and now RE2020), other technical or ATEX opinions are being developed jointly with other building companies, particularly in the field of ITE (External Thermal Insulation). ORSOL thus obtained an ATEx in December 2021 in partnership with ZOLPAN for the installation of ORSOL facings on EPS support (expanded polystyrene insulation). This opens up new technical perspectives for the projects of architects or property developers.
A reinforced quality approach with the validation of new seismic tests
At the heart of its development for many years, the ORSOL quality approach enables the company to offer reliable and durable products for homes and public places.
Their technical and chromatic resistance make them ideal products for indoor and outdoor use. As part of its quality approach, ORSOL therefore takes the greatest care in its manufacturing processes in relation to the recommendations of CERIB (Center for Studies and Research in the Concrete Industry).
With the help of its internal laboratory, ORSOL regularly carries out technical tests, which enables it to verify that its products meet the building standards recommended by the CSTB (Scientific and Technical Committee for Building). These tests are carried out on the main compliance criteria specific to the field of wall coverings, which have made it possible to obtain the following results on ORSOL facings and their accessories:
- Water absorption coefficient by immersion of 6,0% in accordance with standard NF EN 13198-2003
- Freeze/thaw resistance: no appearance defects, spalling, flaking after 25 NF EN 13198 cycles
- Flexural strength: in accordance with standard NF EN 13 748-1: Resistance > 4 MPa.
- Adherence of mortar/adhesive facing pair with initial conditions + after freeze/thaw cycle: Complies with standard NF EN 12004: Tensile strength > 1.72MPa.
- Compressive strength: f(c28)= 50 MPa according to NF EN 12 1390-3.
- Fire resistance: resistant according to European classification A1 (formerly M0)
- Solar absorption coefficient: < 0,7% (except Black, Anthracite, Ton Rocaille, Light Gray and Shaded Gray)
It is in this same perspective of continuous improvement that at the end of 2021, the CSTB carried out seismic tests never before carried out.
The Eurocode 8 test according to standard NF EN 1998-1
A test whose objective is to ensure that in the event of an earthquake, human lives are protected, damage is limited and structures important for civil protection are operational. For this, jointed facings (Manoir collection) and unfilled joints (Rocky Mountain collection) were laid according to the rules of the art on a support to which vibrations are applied. The tests consist of 8 test sequences where these vibrations are gradually increased. The result of these tests proved to be more than satisfactory since the ORSOL facings arrived without any fall or cracking until the last phase of seismic vibrations, supposed to represent the most important earthquake possible in France and in the DOMTOM) .
This new series of tests has therefore provided confirmation that ORSOL facings can be installed throughout France, including in areas where seismicity may be high.
