This document specifies the characteristics for factory made calcium silicate (CS) products with or without lamination or coating intended to be used for the thermal insulation of buildings.

This document is applicable for materials with the main crystal phases Xonotlite and Tobermorite with or without Wollastonite.

This document is applicable for products which are manufactured in the form of boards, segments and prefabricated ware.

This document is applicable for multi-layered CS products.

The products covered by this documents can be used in roofs, walls, ceilings and floors.

This document specifies procedures for assessment and verification of constancy of performance (AVCP) of characteristics of factory made calcium silicate products (CS).

This document does not cover:

  1. products intended to be used for the insulation of building equipment and industrial installations;

  1. products intended to be used for civil engineering works;

  2. with a declared thermal conductivity greater than 0,078 W/(mK) at 10 °C;

  3. aerated concrete, autoclaved aerated concrete, mineral foam insulating products and sand-lime bricks;

  4. in situ insulation products.
