MCRMA Online CPD – GD28 Mineral wool insulation: best practice guide


All buildings whatever their use must provide protection from the external environment and the requirements of the internal environment will depend upon the intended use of the building. Insulating a building is one of the most cost-effective ways of saving energy and reducing heating and cooling bills. Installation practices and procedures at the construction phase must ensure that the insulation of the building fabric, including details and junctions, meets with the design stage calculations, manufacturer’s guidance and Building Regulations.

This CPD sets out an overview of the factors that need to be taken into account when considering the storage, handling and installation of mineral wool insulation in built-up metal roof and wall cladding systems. The CPD examines the design factors that must be considered when specifying mineral wool insulation including the importance of the accurate calculation of the design lambda values and U-values.

Site considerations, including storage, recovery to manufactured thickness and unpacking are examined. The CPD also includes guidance on both roof and wall installation and standards of workmanship. Adoption by industry of the recommendations outlined in this CPD will lead to better and more consistent standards of metal roofing and cladding construction.
