Expanded polystyrene is a cellular insulation material consisting of 98 per cent air trapped within polystyrene beads fused together. For external wall insulation (EWI), it comes in rigid panels measuring 1200 × 600 mm, ready for bonding, fixing and rendering. Centrale ITE offers three performance grades, all ACERMI-certified and classified as Euroclass E:
EPS external wall insulation is installed using an adhesive and dowels, then covered with a reinforced base coat and a finishing render, as part of a system covered by a Technical Approval such as Fassatherm Classic. Starting the installation. An aluminium starter strip, of a width suited to the thickness of the panel, is fitted. Bonding. The panels are bonded using A 96 adhesive-plaster, applied as a perimeter bead and central dots (approximately 4 kg/m²), with staggered joints and no adhesive in the joints. Anchoring. Once the adhesive has set, use at least 5 wall plugs per panel, or approximately 7 per m². Open joints less than 10 mm wide are filled with EPS strips or PU foam. Sanding. Sand the surface with a rasp to make it perfectly flat. Base coat and finish. Apply approximately 4 kg/m² of base coat, using the mesh reinforcement, followed by the primer and the finishing coat.
