Nine Months Sales Report

Compagnie de Saint-Gobain
31 October 2000

CONSOLIDATED SALES FOR THE NINE MONTHS TO SEPTEMBER 30, 2000: up 27.3% 

Net consolidated sales of the Saint-Gobain Group for the nine months to
September 30, 2000 amounted to Euro 21,302 million (FRF 139,732 million), up
from  Euro 16,721 million (FRF 109,683 million) for the same period in 1999,
representing a year-on-year increase of 27.3% (and 31.1% excluding Essilor,
which was accounted for by the equity method as from July 1, 2000). Based on a
comparable Group structure and excluding Essilor, sales were up 11.5% in euros
and 6.3% in local currencies.

This performance must be considered in relation to the strong sales momentum
which the Group experienced in the third quarter of 1999, and it reflects the
Group's growth ability, especially as conditions proved less favorable over the
third quarter of this year, namely in the U.S. construction market.

The breakdown of sales by operating sector, division and major geographical area
is as follows:

(1) including inter-division eliminations

* Accounted for by the equity method as from July 1, 2000

The Glass Sector kept up its growth, in line with its first-half performance,
thanks to sustained demand in all divisions, both in Europe and in the United
States, and to higher selling prices in the Flat Glass and Reinforcements
divisions.

The High-Performance Materials and Plastics Sector experienced trends that are
in line with the Group's average on a comparable basis, even though the
reference point for comparison in the third quarter of 1999 was particularly
high. As previously, operations geared toward the semi-conductors market were
particularly dynamic.

The Housing Sector continued to post strong sales in spite of the slowdown noted
in the third quarter, particularly in the United States, in the Building
Materials division. The Pipe division, for its part, is still faced with a
difficult market environment. The Building Distribution division further
developed, both through organic growth and through acquisitions, in a
still-buoyant European market.

Outlook : With satisfactory levels of growth overall and taking into account the
favorable impact of the latest acquisitions, the Group confirms its objective
for the full year 2000 of 15% growth in earnings per share excluding capital
gains, to which will be added the impact of the 5% capital reduction (of which
3.85% has already been carried out by June 30, and the balance before the end of
November).
