SAINT-GOBAIN ISOVER TO CONSTRUCT A NEW INSULATING MATERIAL PLANT IN FRANCE



Saint-Gobain Isover is to build a new, 70,000-ton capacity glass wool plant in
Chemille, (Maine-et-Loire) France. The plant is due to begin production at the
end of 2008, will create approximately 150 jobs.

This investment, which stands at around Euro100 million, is designed to address
demand in fast-growing insulation markets in Western Europe and particularly in
France.

New regulatory requirements regarding the thermal performance of new and
existing buildings should result in a 40% reduction of energy consumption in new
buildings by 2020, and a fourfold reduction of energy consumption in existing
buildings by 2050. The thermal insulation of buildings leads to substantial
savings and is one of the most effective ways of combating greenhouse gas
emissions.

Cutting edge techniques incorporating the latest environmentally-compliant
practices will be used in the design and construction of this plant, which will
adhere to HQE(R) (High Environmental Quality) guidelines.

This strategic project will enable Saint-Gobain Isover to meet the strong demand
for insulation products on a buoyant construction market, while at the same time
extending its product range and maintaining its worldwide leadership.



Saint-Gobain Isover forms part of Saint-Gobain's Construction Products sector.
With 45,000 employees worldwide and 250 consolidated companies, the Construction
Products sector is a leader in all its businesses: insulation (Isover), gypsum
(Placo, Gyproc, Rigips, ProRoc), outdoor living products (CertainTeed),

sales of Euro10.9 billion, representing 26% of the Saint-Gobain Group's overall
sales.
