Built-up metal wall systems typically consist of a low profile metal inner liner sheet, separated from an outer, higher profile metal weather sheet and are typically assembled on site.
The cavity between them is filled with a layer of insulation to provide the specified level of thermal performance.
As well as thermal performance acoustic performance is also important. Our Mineral Wool insulation solutions for built-up metal walls provide excellent levels of sound absorption, reducing the drumming effect of rainwater on walls and improving the overall acoustic performance of the wall.

Why Mineral Wool?
Mineral Wool provides the best combination of thermal, fire safety and acoustic performance.
Mineral Wool is easier to install correctly than other insulants such as rigid boards because it adapts to any slight imperfections in the substrate and knits together, eliminating any air gaps. Evidence shows the absence of air gaps is crucial to achieving real performance in the relevant application.
