Nine Months Sales Report

Compagnie de Saint-Gobain
30 October 2001



   CONSOLIDATED SALES FOR THE NINE MONTHS TO SEPTEMBER 30, 2001: up 7.6% 

Net consolidated sales of the Saint-Gobain Group for the first 9 months of
2001 were up 7.6% year-on-year (12.8% excluding Essilor), to EUR 22,932
million, from EUR 21,302 million for the same period of 2000.

Based on a comparable Group structure and excluding Essilor, sales were up
2.2% in euros and 1.9% in local currencies. 

These figures are attributable to mixed trends in the third quarter. At the
end of August, the Group had posted sales growth of 15.7% excluding Essilor
and 2.9% on a like-for-like basis, revenues fully in line with its forecasts
for the second half. In September, however, sales contracted by 3% on a
comparable structure and in local currencies. The decrease was strongest in
High-Performance Materials (Ceramics & Plastics and Abrasives) and
Reinforcements, as a result of the slowdown in industrial output and capital
expenditure affecting both the United States and Europe, particularly since
the events of September 11th

The breakdown of sales by business sector, division and geographic area is as
follows:

which date the Group disposed of its entire stake in the company.

Group sales in third-quarter 2001 remained on a par with those of the same
period in 2000, on a like-for-like basis, as higher sales prices practically
offset declining volumes. For the first nine months of 2001, prices rose
3.7%, while volumes slipped 1.8%, with a 6.8% drop for the month of
September alone.

The Glass Sector recorded the Group's strongest growth, in line with its
first-half performance. Demand remains strong in Automotive Flat Glass and
Containers, but has slowed down in operations related to the building
industry in Europe and fallen in Reinforcements. The business sector as a
whole continues to enjoy high prices, especially in Flat Glass and
Reinforcements.

The High-Performance Materials and Plastics Sector experienced a new decrease
in sales in the third quarter of the year. In addition to the continuing
decline in the global electronics market, the Ceramics and Plastics division
recorded, in the third quarter, a slowdown in most industrial markets,
particularly those related to equipment and capital expenditure. The
Abrasives division, which had already suffered from the downturn in U.S.
manufacturing output in the first half, saw a significant contraction in its
European sales in the third quarter.

The Housing Products Sector posted higher sales in the third quarter,
particularly in the Building Materials and Pipe divisions. The Building
Materials Distribution division experienced vigorous sales in France and the
United Kingdom, but was hampered in Germany by the continuing slowdown in the
building industry.

By geographic area, sales trends for the third quarter show that France
continued to record strong activity levels, but the German market declined
sharply. In the United States, the Insulation and Building Materials
divisions continued to grow, boosted by a healthy construction market. In
Ceramics & Plastics, Abrasives and Reinforcements, however, volumes fell
abruptly due to the drop in manufacturing-industry demand.

Outlook: Last January, the Group had set as its objective a 10% increase in
net income excluding capital gains, 'provided there (was) no new and
significant deterioration in the economic environment.' As a result of the
slowdown in activity experienced in September, particularly in areas related
to capital expenditure, added to the high level of uncertainty surrounding
the world economy, the Group now sets as its objective for the full year 2001
growth of between 1% and 5% in its net income excluding capital gains.
