Contact Resistance

In NZS 4214:2006 "Thermal insulation - Housing and small buildings," Contact Resistance refers to the thermal resistance caused by the contact between two surfaces. It aims to account for the reduction in thermal conductivity due to air gaps or imperfect contact between insulation materials and building components.
