In the field of insulation techniques, technical advances are mainly due to an interactive approach resulting from three complementary factors: * National building standards and government supported incentive programmes which aim to increase the thermal efficiency of residential and commercial buildings. * Research and Development programmes set up by manufacturers in order to lead to new or improved insulation materials or components with increasing R-values. * New construction techniques used by designers and builders to reduce heat loss through building envelopes.

Describes the French ACERMI Certification governing thermal insulation. It aims at setting competition between products according to objective bases on both a national and international level; making it possible for the users to select products easily and under optimal saving conditions; and ensuring them, without their having to check, that the product delivered to them has the characteristics expected.

The annex was formed to address energy issues related to low slope roof systems. The first task undertaken was the development of a sourcebook on good practices for design, installation and maintenance of insulated roof systems. The intent of the sourcebook is to provide a discussion of both real and perceived correlations between roof systems and to present information on recent roofing issues that have insulation implications. Annex members have identified and reviewed a list of 25 potential correlations between roof problems and insulation.
