What is lifetime performance of INSULITTE concrete?
In order to ensure the expected energy savings, it is important that the insulation concrete like INSULITTE does not deteriorate, or settle, over time, as it is siliceous ash. Fiber glass and rock and slag wool loose-fill insulations may settle approximately 1-3% resulting in virtually no impact on the thermal performance of the insulation. In contrast, cellulose insulation not only settles to a much greater degree (approx. 20%), but also at a higher rate. If cellulose insulation is being considered, make sure the installer understands that most cellulose insulations settle in attic loose-fill applications – that’s a significant loss of insulating effectiveness.
