Insulation materials and their thermal properties

Thermal insulation is the reduction of heat transfer (the transfer of thermal energy between objects of differing temperature) between objects in thermal contact. It is commonly used as a insulation sheet.

Performance

The most important aspect of an insulation material is its performance – that it consistently provides the designed-for resistance to the passage of heat throughout the lifetime of the building. Though the insulation manufacturer's published performance expectations will be an essential guide, other factors associated with the "real-life" installation of the material need to be considered as part of the design process:

? Ease of installation – the ultimate performance will be determined by how effectively a builder can install a material using conventional skills. For example, insulation slabs need to be installed so that no gaps result either between adjoining slabs, or between the slabs and other construction components that form part of the overall insulation envelope, such as rafters or joists. Any gaps left over will enable the passage of air and result in a reduction in performance.

? Shrinkage, compaction, settlement – Some materials are likely to suffer a degree of dimensional instability during their installed life. In many instances this is anticipated and can be overcome through careful design and installation methods. In all other instances, the specifier should seek guidance concerning associated risks from the insulation manufacturer – particularly where materials have not had an established record of installed performance.
