Key points
A practical comparison of insulation choices for aluminum metal roofs, industrial plants and public building projects.
The building requirement comes first
Thermal performance, fire requirements, acoustic needs, moisture control and construction conditions should be identified before selecting an insulation material.
Rock wool and glass wool serve different conditions
Their density, thermal properties, fire behaviour, acoustic performance and installation requirements should be compared against the project design rather than selected by price alone.
Coordinate the whole roof build-up
The insulation layer works with the metal panel, vapor control, waterproofing, clips, substrate and edge details as a complete roof construction.
