               NOTES TO CONSOLIDATED FINANCIAL STATEMENTS



Basis of Presentation

  In the opinion of management, the accompanying unaudited consolidated
financial statements contain all adjustments (which consist solely of normal
recurring adjustments unless otherwise disclosed) necessary to present fairly,
in all material respects, its financial position as of December 31, 1998 and
June 30, 1998, and the results of operations for the three and six month
periods ended December 31, 1998 and 1997 and the cash flows for the six month
periods ended December 31, 1998 and 1997.  The results of operations for the
three and six month periods ended December 31, 1998 and 1997 are not
necessarily indicative of the results to be expected for the full year.

  The financial statements included herein have been prepared by the Company
pursuant to the rules and regulations of the Securities and Exchange
Commission.  Certain information and footnote disclosures normally included
in financial statements prepared in accordance with generally accepted
accounting principles have been condensed or omitted pursuant to such rules
and regulations, although the Company believes that the disclosures are
adequate to make the information presented not misleading.  It is suggested
that these financial statements be read in conjunction with the financial
statements and the notes thereto included in the Company's latest annual
report on Form 10-K.

  This report contains forward-looking statements with respect to the
financial conditions, results of operations and business of the Company.  Such
items are subject to certain risks and uncertainties that could cause actual
results to differ materially from those set forth in such statements.


Comprehensive Income

  Comprehensive income, defined as net income and other comprehensive income,
for the second quarters ended December 31, 1998 and 1997 was $2,793,000 and
$1,706,000, respectively.  Comprehensive income for the six months ended
December 31, 1998 and 1997 was $6,089,000 and $4,275,000, respectively.  Other
comprehensive income includes foreign currency translation adjustments
recorded directly in shareholders' equity.


Disposition of Foreign Subsidiary

  During the second quarter of the prior year, the Company sold its Dutch
subsidiary, Eland-Brandt BV, for approximately $1,021,000 in net cash
proceeds.  The sale generated a pretax gain of $1,235,000 (after-tax gain of
$1,156,000 or $.27 per share), including the recognition of $2,145,000 of
previously deferred cumulative translation adjustment.  The Company's
consolidated financial statements for the prior year include the results of
Eland-Brandt through the date of disposal.

       MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                        AND RESULTS OF OPERATIONS




Significant Changes in Results of Operations

  Sales increased by $5,610,000 or 10.1% for the quarter ended December 31,
1998 and increased by $8,251,000 or 7.2% for the six months then ended when
compared with the 1997 periods.  The sale of the Company's Dutch subsidiary,
Eland-Brandt BV, during the prior year impacts period comparisons.  Exclusion
of Eland-Brandt from the prior year results in increases of $5,610,000 or
10.1% for the quarter and $10,234,000 or 9.0% for the six months.  Sales from
continuing operations include increases of $2,461,000 or 8.7% for the quarter
and $7,229,000 or 13.0% for the six months by the Commercial Products Group
and $2,303,000 or 20.1% for the quarter and by $2,435,000 or 10.0% for the six
months by the Residential Products Group.

  Cost of sales as a percentage of net sales increased by 1.0% for the quarter
ended December 31, 1998 but decreased by 0.1% for the six months then ended
when compared with the 1997 periods.  Exclusion of Eland-Brandt from the prior
year results in increases of 1.0% for the quarter and 0.4% for the six months
which are primarily attributable to slightly increased labor percentages
incurred by each of the Company's operating groups during the second quarter
of the current year.

  Selling, general and administrative expenses increased by $2,484,000 or
17.5% for the quarter and by $3,277,000 or 11.7% for the six month period. 
The expenses from continuing operations increased by $1,249,000 for the
quarter and by $2,452,000 for the six months associated with the increased
sales volume.  The non-recurring portion of the changes relate to the sale of
the subsidiary during the prior year.

  The increase in net interest income for the six month period relates to the 
increased level of funds available for investment during the first quarter of
the current year.

  The effective tax rate for the six months ended December 31, 1998 was 38.3%
whereas the comparable period of the prior year was 37.8%.  This increase is
primarily related to the sale of the foreign subsidiary in the prior year
which incurred a small taxable gain in relation to the book gain.

Liquidity and Capital Resources

  Working capital at December 31, 1998 stood at $70,870,000, a decrease of
$1,300,000 from June 30, 1998.  The ratio of current assets to current
liabilities is currently 4.1 as compared to 4.7 as of the beginning of the
year.  

  In addition to the $1,300,000 cash purchase of business assets in Colorado
(see the note below), the Company's projected capital expenditures for fiscal
1999 include $14,000,000 for scheduled expansion of production capacity in
addition to the normal annual noncapitalized expenditures for replacement
items.  The Company anticipates financing these expenditures through internal
cash flow, cash reserves and the utilization of its line of credit.  

  The Company's line of credit remains unchanged from that noted in the
June 30, 1998 Annual Report to Shareholders.


Year 2000

  The Company performed a review of the financial and operational software it
uses in its business for Year 2000 compliance and determined that it was not
compliant.  The Company is in the process of migrating to new compliant
releases of its financial software.  The Company had previously purchased new
operational software to be used by all of its entities to enhance
manufacturing information and customer service.  The Aluminum Extrusion and
Glass Products groups have completed implementation of this new software,
which is Year 2000 compliant.  The Commercial and Residential Products groups
have completed partial implementation, with at least one member of each group
being completed.  The Company has targeted Year 2000 compliance of its
financial and operational software by no later than mid-1999, and thus has not
developed contingency plans.

  The Company will continue to incur expenses related to these efforts,
however, such expenses are not expected to have a material impact on the
Company's results of operations.  Although not anticipated, the consequence
of non-compliance by the Company, its customers or its suppliers could have
a material adverse impact on the Company's operations.  


New Domestic Subsidiary

  The Company recently formed a  wholly-owned subsidiary named International
Window-Colorado, Inc. which will conduct business as International
Window/Excel (IW/E) and be a member of the Residential Products Group.  On
October 1, 1998, IW/E completed the $1,300,000 cash purchase of selected
assets and liabilities of a Denver, Colorado residential window and door
company.  The estimated fair value of the net assets acquired was $726,000. 
The $574,000 excess of the purchase price over the estimated fair value was
allocated to goodwill and is being amortized on a straight line basis over 15
years.
