BS EN ISO 13786:2007 Thermal performance of building components. Dynamic thermal characteristics. Calculation methods

BS EN ISO 13786 specifies the characteristics related to the dynamic thermal behavior of complete building components and provides a method for calculation of this behavior. It also specifies information on building materials required for the use of the building component.

BS EN ISO 13786 also provides a simplified calculation method for plane components consisting of plane layers of substantially homogeneous building materials.

BS EN ISO 13786 does not apply to building materials or to unfinished building components.
