Trend in the number of certificates issued

Trend in the number of certificates issued

Since ACERMI was founded in 1984, the number of ACERMI-certified products has increased consistently to a total of 654 by the end of 2013.

The strong growth achieved over the last six years has seen the number of certificates more than double, from 300 to 650. This increase is explained chiefly by the introduction of new regulations (RT 2012) requiring the development of increasingly efficient products (higher lambda values), the ongoing introduction of new materials (cellulose wadding-based products, sprayed mineral wool-based products, etc.), and the introduction in 2013 of the springboard standard.

Breakdown of insulating materials certified

The diversification of products certified has accelerated over the last five years, with strong demand coming from manufacturers of wood fiber and wood wool, and the introduction of new products, such as cellulose wadding-based products and sprayed mineral wool-based products.

A new springboard standard has been developed with the aim of providing certification for products not currently covered by the ACERMI general guidelines; after 3 years of this certification, the products concerned will gain their own dedicated standard, and will have been certified throughout this period. The types of product covered by this standard include: bulk cotton, composite panels, polyester fiber, bulk cellular glass, vacuum products and polystyrene formwork blocks.

Geographic breakdown of production plants audited

ACERMI-certified products come essentially from European production plants, half of which are outside France. All these plants are audited twice yearly by ACERMI (LNE or CSTB) auditors to ensure consistent monitoring of ACERMI-certified products and all aspects of their performance.

The main producing countries of insulating materials and products certified by ACERMI are France, Germany, Belgium, Switzerland and Spain. One production plant in the USA has been ACERMI-certified since 2010.

Changes to the guidelines

The most recent changes to ACERMI guidelines concerned the inclusion of cellulose wadding products (2011), the inclusion of sprayed bulk mineral wool-based products (2011) and the revision of guidelines with the introduction of product-specific specifications for each product (2013).

The springboard standard was introduced in 2013 to enable inclusion of new materials such as bulk products (cotton, wood fiber, etc.), vacuum products and highly innovative products generally...
