APPLICATION OVERVIEW
In an external wall, insulation is required for thermal performance to reduce unwanted heat loss from the building, and acoustic performance to alleviate any unwanted external noise.
In this application, the mineral wool insulation is installed to the external fabric of an existing or new building, and is finished with a render coat. When non-combustible insulation is used, no additional fire breaks are required.
Important factors to consider when specifying an external wall insulation solution include the level of thermal performance to be achieved, which finish is the most suitable and the reaction to fire classification of the insulation.
RECOMMENDED PRODUCT
Why Mineral Wool?
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.
