Frequently Asked Questions

CEN/TC 89/WG 2 is a Working Group within the European Committee for Standardization (CEN). It is named "Thermal transmittance" and is responsible for: To draft standards for the calculation of thermal transmittance of building components and building elements including the establishment of methods for determining design thermal values of materials and products. Thermal insulation of installed equipment is excluded. This committee has published 3 standards.

CEN/TC 89/WG 2 develops CEN standards. The scope of work includes: To draft standards for the calculation of thermal transmittance of building components and building elements including the establishment of methods for determining design thermal values of materials and products. Thermal insulation of installed equipment is excluded. Currently, there are 3 published standards from this working group.

The European Committee for Standardization (CEN) is a public standards organization that brings together the national standardization bodies of 34 European countries. CEN provides a platform for developing European Standards (ENs) and other technical documents in relation to various products, materials, services, and processes, supporting the European Single Market.

A Working Group in CEN is a specialized group responsible for developing standards or technical work within a defined scope. These bodies bring together international experts to create consensus-based standards that support global trade, safety, and interoperability.

EN 12524:2000(Main)
Building materials and products - Hygrothermal properties - Tabulated design values
SIST EN 12524:2001

This standard gives design data in tabulated form for heat and moisture transfer calculation, for thermally homogeneous materials and products commonly used in building construction. It also gives data to enable the calculation and conversion of design thermal values for various environmental conditions.

CEN
EN ISO 6946:1996(Main)
Building components and building elements - Thermal resistance and thermal transmittance - Calculation method (ISO 6946:1996)
SIST EN ISO 6946:1997

This standard gives the method of calculation of the thermal resistance and thermal transmittance of building components and building elements, excluding doors, windows and other glazed units, components which involve heat transfer tothe ground, and components through which air is designed to permeate. The calculation method is based on the appropriate design thermal conductivities or design thermal resistances of the materials and products involved. The method applies to components and elements consisting of thermally homogeneous layers (which can include air layers).
