1. The Fort Mitter "rock wool board" external wall thermal insulation system is a high-performance, fire-resistant solution designed for energy-efficient buildings. It utilizes water-repellent rock wool boards manufactured using the pendulum method as the primary insulating material. These boards are securely attached to the base wall through a combination of bonding and nail-bonding techniques. The system features a surface layer made of a bonding agent, reinforced glass fiber mesh, and a finishing coat such as decorative mortar or paint. Developed by Baumit, one of Europe’s leading insulation brands, this A-class non-combustible insulation system has been certified with European Technical Approval (ETA) after more than three decades of successful performance in fire and thermal protection applications.

2. The system consists of several key layers: a bonding layer, an insulation layer, a leveling layer, a finish layer, and additional accessories. The finish layer should be breathable and lightweight, such as a functional facing mortar, decorative mortar, or a water-based exterior coating that allows moisture to escape while maintaining aesthetic appeal.

3. This rock wool board insulation system offers excellent thermal performance due to its low thermal conductivity and superior air permeability. It provides high fire resistance and is suitable for both new and renovated residential and commercial buildings. It can be used for exterior wall insulation, non-transparent curtain wall insulation, and as a fire barrier in EPS (expanded polystyrene) insulation systems. Its versatility makes it ideal for a wide range of energy-saving projects across different building types.
