Flat Roofs
Holcim, a leader in innovative and sustainable building solutions, manufactures stone wool boards for flat roof insulation in single-layer and multi-layer systems. Our solutions provide effective thermal protection, A1-class fire resistance, and high mechanical load resistance, making them ideal for the most demanding operating conditions. The boards are characterized in particular by dimensional stability, resistance to temperature fluctuations and moisture, as well as excellent adhesion to roofing layers – both roofing felt and bituminous or synthetic membranes. With a wide range of technical parameters, our offer includes base boards, top layers, and supplementary layers, enabling the design of effective roof systems tailored to any type of building, from industrial warehouses to residential buildings. This is a proven and durable solution for those who expect reliability for generations.
