</TABLE>

     Net sales for the three months ended June 30, 2000 were $93.2 million, an
increase of $12.2 million from the three months ended June 25, 1999. This
increase was primarily due to growth in sales volume in the packaging and
insulation segment and increased pricing across all operating segments. Gross
profit for the three months ended June 30, 2000 increased by $1.9 million to
$25.1 million from $23.2 million for the same period in 1999. This increase was
primarily caused by increased net sales as well as improved manufacturing
efficiencies, partially offset by increased raw material costs and the time lag
between rising styrene monomer prices and increases in EPS selling prices.
Operating expenses for the three months ended June 30, 2000 increased to $18.4
million from $16.8 million for the same period in 1999 primarily due to selling
expenses which vary as a function of sales and increased corporate operating
costs.

     Net sales for the six months ended June 30, 2000 were $174.5 million. This
$25.8 million or 17.4% increase from the same period in the prior year was
primarily due to growth in sales volume in the packaging and insulation segment
and increased pricing across all operating segments. Gross profit for the six
months ended June 30, 2000 increased by $1.6 million to $43.3 million from $41.7
million for the same period in 1999. This increase was primarily caused by
increased net sales as well as improved manufacturing efficiencies, partially
offset by increased raw material costs and the time lag between rising styrene
monomer prices and increases in EPS selling prices. Operating expenses increased
by $3.0 million to $35.0 million for the six months ended June 30, 2000 due to
higher selling and distribution costs as well as increased amortization of
intangible assets.

     Net sales in the packaging and insulation business segment increased by
$5.1 million to $64.4 million for the three months ended June 30, 2000 primarily
due to volume growth and increased pricing. Gross profit declined to 27.0% of
net sales for the three months ended June 30, 2000 from 30.9% of net sales for
the same

period in 1999 primarily due to increased raw material and energy costs,
partially offset by improved manufacturing efficiencies. Operating expenses
increased to $11.5 million for the three months ended June 30, 2000 from $10.8
million for the same period in 1999 primarily due to higher selling costs in the
domestic packaging business. Income from operations decreased by $1.6 million
for the three months ended June 30, 2000 over the same period in 1999 for the
reasons described above.

     Net sales for the six months ended June 30, 2000 were $119.1 million.  This
$9.8 million or 9.0% increase over the six months ended June 25, 1999 was
primarily due to increased pricing and volume growth.  Gross profit as a
percentage of net sales decreased to 27.3% for the six months ended June 30,
2000 from 31.0% for the same period in 1999.  This decrease was primarily caused
by increased raw material and energy costs, partially offset by improved
manufacturing efficiencies.  Operating expenses increased by $1.9 million to
$22.0 million for the six months ended June 30, 2000 due to higher selling and
distribution costs.  Income from operations decreased by $3.3 million for the
six months ended June 30, 2000 over the same period in 1999 for the reasons

</TABLE>

     Net sales for the second quarter of fiscal 2000 increased to $37.4 million
from $28.7 million for the same period in 1999, primarily due to increased
selling prices.  Net sales for the three months ended June 30, 2000 and June 25,
1999 included sales to the packaging and insulation segment of $9.2 million and
$7.5 million, respectively.  Gross profit increased $2.3 million to $6.6 million
for the three months ended June 30, 2000.  As a percentage of net sales, gross
profit increased to 17.6% for the second quarter of fiscal 2000 from 15.0% for
the same period in 1999.  This increase was primarily caused by increased
selling prices and manufacturing efficiencies throughout the segment, partially
offset by the time lag between rising styrene monomer costs and sales price
increases.  Operating expenses decreased $0.3 million to $4.0 million for the
three months ended June 30, 2000 primarily as a result of cost containment
initiatives.

     Net sales in the specialty chemicals segment increased by $18.5 million to
$68.3 million for the six months ended June 30, 2000 primarily due to increased
selling prices. Gross profit increased $2.2 million to $8.7 million for the six
months ended June 30, 2000. This increase was primarily caused by increased net
sales as well as improved manufacturing efficiencies, partially offset by the
time lag between rising raw material costs and selling price increases during
the beginning of the period. Operating expenses decreased $0.3 million to $7.8
million primarily as a result of cost containment initiatives.

Corporate & Other

     For the three month and six month periods ended June 30, 2000, corporate
operating expenses increased by $1.1 million and $1.4 million, respectively,
from the same periods in 1999.   This increase was primarily due to increased
amortization of intangible assets and increased operating costs at the Company's
executive offices.

</TABLE>

  Interest expense for the three months and the six months ended June 30, 2000
increased by $0.4 million and $0.8 million, respectively, over the same periods
in 1999. These increases were primarily due to an increase in interest rates,
greater borrowings related to the purchase of the Company's Tolleson, Arizona
facility and other capital expenditures, and an increased level of working
capital.

  The effective tax rate for the three months ended June 30, 2000 increased to
38.0% of pre-tax income from 36.5% of pre-tax income for the same period in
1999.  The effective tax rates for the six months ended June 30, 2000 and June
25, 1999 were 38.0% and 37.7% of pre-tax income, respectively.  As of June 30,
2000 the Company had approximately $49.4 million of net operating loss
carryforwards for federal income tax purposes, which expire through 2020.

Liquidity and Capital Resources
-------------------------------

  During the six months ended June 30, 2000 and June 25, 1999, the Company's
principal source of funds consisted of cash from financing activities. During
the 2000 period, after tax cash flow of $6.4 million, net borrowings on bank
financed debt and capital leases of $13.7 million and a decrease in cash of $3.5
million were primarily used to fund capital expenditures of $4.9 million and a
$17.6 million increase in working capital.

  As of June 30, 2000 the Company had $33.5 million outstanding and $7.9 million
of availability under its revolving credit agreements.  The principal uses of
cash for the next several years will be working capital requirements and capital
expenditures.

  As a holding company, Radnor Holdings Corporation is dependent upon dividends
and other payments from its subsidiaries to generate the funds necessary to meet
its obligations.  Subject to certain limitations under applicable state law and
the Company's credit agreements, Radnor Holdings Corporation is, and will
continue to be, able to control its receipt of dividends and other payments from
its subsidiaries. Management believes that cash generated from operations,
together with available borrowings under the revolving credit facilities, will
be sufficient to meet the Company's expected operating needs, planned capital
expenditures and debt service requirements.
