A micron is simply a measurement of thickness where 1000 microns is equal to 1mm. 200 Microns gives the best performance with Rapid Response® in all property types. Suitable for all Refurbishments and Renovations. 100 Microns is a medium foil covering offering good response in well insulated properties where rapid response is not required. 50 Microns is a thin foil covering giving slower performance and is only suitable for New Builds where rapid response is not required. Plain boards with no foil are only suitable for brand new highly insulated properties.

Please note: Output and system performance is dependent on insulation standards and environmental conditions.
