5 cm / 50 mm PETRALIGHT mineral wool board

A home should offer space for rest, conversation and concentration. Mineral wool encourages a view of insulation that goes beyond winter energy bills. Its fibrous structure reduces heat transfer and can support acoustic protection within an assembly, while the mineral raw material provides useful fire-related properties. It is suitable for many parts of a building where everyday comfort matters.

Air trapped between the fibres helps limit heat conduction. Appropriately selected insulation helps maintain indoor temperature and reduces heat entering through building elements in summer. Mineral wool comes in types designed for different tasks, so a façade board has different performance characteristics from lightweight partition infill. This variety allows insulation throughout a home to be planned for the conditions at each location. Owners can choose a material for a wall, roof or floor rather than expecting every product to serve the same function.

The fibres help dissipate sound energy in an appropriately designed assembly. This matters when creating a study, a child’s room or a bedroom beside the living area. Performance depends on the complete wall, but mineral wool is a useful component of an acoustic solution. Many mineral products also offer non-combustibility confirmed by the individual product classification. Thermal objectives can therefore be considered alongside safety requirements. Vapour permeability also gives designers options for controlling water-vapour movement through the assembly.

A wide choice of forms and densities allows insulation to be matched to lightweight construction and loaded surfaces.

Resilient types fill the planned spaces between structural members effectively.

Façade products provide insulation beneath a finish compatible with the selected system.

In an appropriate assembly, fibrous insulation can reduce heat loss and absorb sound energy at the same time.

Mineral wool is useful in buildings whose rooms serve different purposes. In a loft it helps create comfortable living space; in lightweight partitions it can reduce speech transmission; on a façade it forms part of a suitable insulation system. Consider these uses in relation to how the home is occupied. A quiet study has different priorities from a heated room above a garage, although both can use this material family. Choosing the specific type matches resilience, stiffness and performance to the building element, creating consistent conditions for work and rest.

SteelProfil offers mineral wool and a wide selection of first- and second-grade insulation. Stock availability, competitive pricing and promotions help plan the purchase. We can match the board type to the building element’s function, taking account of occupants’ needs, the intended finish and the conditions in which the material will be used.
