Mineral insulation that is fire-resistant

Rock wool is a mineral insulation material made from molten, fibrous volcanic rock. In external wall insulation (EWI) systems, it is installed in the form of rigid panels to be rendered over, and offers three advantages that plastic insulation materials do not have: it is non-combustible, it allows the wall to breathe, and it reduces external noise. Centrale ITE’s benchmark panel is the Re Coat+ from Termolan. It is a bare, single-density panel, designed for external thermal insulation composite systems (ETICS). Its ACERMI-certified characteristics are:

  • thermal conductivity λD 0.035 W/m·K;
  • fire reaction Euroclass A1;
  • compressive strength CS(10)30;
  • perpendicular tensile strength TR7.5;
  • low water absorption (WS);
  • thickness tolerance T5.
It is available in thicknesses from 80 to 200 mm, with R-values ranging from 2.25 to 5.70, including 140 mm (R 4.00), 160 mm (R 4.55) and 180 mm (R 5.10). Thermolan N50F, available from 20 to 50 mm, is used for wall panels, window reveals and where thin thicknesses are required. Rock wool is also highly vapour-permeable (MU1, according to the Isofacade 35R certificate). On an old stone or brick wall, it allows moisture to escape to the outside.

Installation of rock wool external wall insulation: bonding, fixing with dowels and rendering

Meticulous installation for a safe and durable façade

Rock wool external wall insulation is installed using an adhesive and dowels, with stricter requirements than for polystyrene, as the insulation is heavier and more fibrous. Installing the panels.

  • The panels are bonded using A 96 adhesive-plaster, a thin layer of which is worked into the surface of the panel before the adhesive is applied.
  • They are installed with staggered joints, starting from a starter rail.
  • They are fixed with steel nail plugs, combined with a large-diameter anchor plate where required by the Technical Approval Document (DTA).
The base coat. This is thicker than on EPS: the Fassatherm Plus MW technical approval specifies approximately 4.2 kg/m² for the first coat, followed by 2.1 kg/m² for the second coat, totalling approximately 6.3 kg/m², with the fibreglass mesh embedded between the two coats. The finish. To preserve the wall’s vapour permeability, a vapour-permeable finish is preferred, such as Fassil R 336 silicate render. Fire-stop strips. The Kardigan fire-stop strip (1200 × 200 mm, 180 mm thick) allows rock wool strips to be incorporated into a polystyrene external thermal insulation system (ETIS) where required by fire safety regulations. At the junctions between the two insulation layers, the reinforcement must extend at least 20 cm beyond each one.

How to choose your external insulation?

Steps involved in an EWI installation

Which fixing for which substrate?

Rock wool panels for external wall insulation are non-combustible (Euroclass A1), vapour-permeable and provide effective reduction of external noise. They are the insulation of choice when fire safety, older buildings or acoustic comfort are key considerations. Centrale ITE offers ACERMI-certified panels ranging from 60 to 200 mm and fire-stop strips, at trade prices for both private individuals and professionals.

Rock wool: three questions

Elle est incombustible, ce qui en fait la solution de référence lorsque la réglementation incendie est exigeante. Elle offre aussi un bon confort acoustique et reste perméable à la vapeur d'eau.
Elle est collée puis chevillée, souvent avec des rosaces pour bien répartir l'effort. Utilisez des panneaux haute densité conçus pour l'ITE sous enduit.
Oui, des bandes de laine de roche servent de recoupements coupe-feu dans les ITE en PSE lorsque la réglementation l'impose.
