Overview of EWI Systems: The document discusses two types of External Wall Insulation (EWI) systems: Mineral Wool and Wood Fibre Board. Both systems are designed to enhance thermal performance and provide weather protection for building facades.

Mineral Wool System: This system is vapour permeable, offering dimensional stability and fire safety, suitable for commercial and multi-storey buildings. It is ideal for upgrading the thermal performance of solid concrete and masonry constructions. The system includes components such as DC56 bonding mortar, mineral wool board, base coat, mesh system, primer, and top coat systems. Mineral wool provides excellent acoustic, thermal, and breathable properties, reducing the risk of condensation.

Wood Fibre Board System: Made from renewable materials, this system is fully recyclable and offers excellent thermal insulation with a low carbon footprint. It is suitable for both existing and new constructions, providing a natural solution for thermal upgrades. The system includes wood fibre board, MC55 base coat, mesh system, primer, and top coat systems. It offers good thermal comfort and guards against summer overheating.

System Support and Specification: Lime Technology provides a comprehensive supply and specification package, including technical advice, psi and U-value calculations, and dew point analysis. They offer a 20-year guarantee on their systems, with additional insurance options available.

Training and Support: Installation of EWI systems requires certified operatives. Lime Technology offers full system application training and on-site supervision to ensure proper installation.
