  ITEM 1.  BUSINESS

  a. GENERAL DEVELOPMENT OF BUSINESS

       International Aluminum Corporation is an integrated building
  products manufacturer of diversified lines of quality aluminum,
  vinyl, wood and glass products.  The Company was incorporated in
  California in 1963 as successor to an aluminum fabricating
  business begun in 1957 and maintains its executive offices at 767
  Monterey Pass Road, Monterey Park, California 91754.  The
  Company's telephone number is (323) 264-1670.  Reference to the
  "Registrant", "International Aluminum Corporation" or the
  "Company" includes International Aluminum Corporation and its
  subsidiaries unless the context indicates otherwise.


  b. INDUSTRY SEGMENTS, LINES OF BUSINESS AND CLASSES OF PRODUCTS

       This information is included on pages 4 and 15 of the
  Registrant's 1999 Annual Report to Shareholders and is hereby
  incorporated by reference.


  c. NARRATIVE DESCRIPTION OF BUSINESS

  Processes and Products

      Residential

       Residential products are fabricated from aluminum, vinyl and
  wood into a broad line of horizontal sliding windows, vertical
  sliding windows, casement windows, garden windows, bay and bow
  windows, special configuration windows, louvre windows, patio
  doors, tub enclosures, shower doors, wardrobe mirror doors and
  related products.  These products are used in new residential
  construction and in remodeling, home improvement and replacement.

      Commercial

       Commercial products are fabricated from aluminum into
  curtain walls, window walls, storefront framing, entrance doors
  and frames for exterior applications and officefronts, office
  partitions, doors and frames for interior applications.  These
  products are utilized in varying combinations to produce systems
  used for office and commercial construction, remodeling and
  tenant improvement applications.

      Aluminum Extrusion

       In the extrusion process, heated aluminum billets are
  hydraulically forced through steel dies to produce a piece of
  metal of the desired cross-sectional shape and length.  The
  extrusions are then cut and, when requested, anodized or painted
  in a variety of finishes in the Company's anodizing and painting
  departments.

      Aluminum extrusions produced by the Company are used in
  fabricating substantially all of its other aluminum products.
  In addition, during fiscal 1999 approximately 49% of the
  extrusions produced were sold to users in its own or other
  industries, including manufacturers of fixtures, electronic
  equipment, automotive products, sailboats, skylights and truck
  bodies.  The Company furnishes design services to assist its
  customers in developing or better utilizing custom extrusions.

      Glass

       This product group shapes, bends, bevels, etches, polishes
  and tempers bulk flat glass.  The fabricated glass is primarily
  utilized in the Company's store fixturing products and in its
  glass furniture lines.  Glass is also processed to customer
  specifications for incorporation into their end products, which
  include residential, patio and office furniture, truck and
  recreational vehicle windows, light fixtures and appliances.


  Sales and Distribution

      The Company markets its residential products primarily to
  mass merchandisers, independent dealers and distributors, with
  whom the Company has no long-term contracts.  Commercial building
  products are marketed primarily to glazing and tenant improvement
  contractors.  Aluminum extrusions are marketed principally by
  direct sales to other manufacturers.  The Company's glass
  products are marketed to manufacturers, distributors and
  retailers.

      Each of the Company's subsidiaries has its own administrative
  and sales organizations.  Sales are made primarily in North
  America.

      No customer accounted for more than 5% of net sales in 1999,
  and no material part of the business is dependent upon a single
  customer or a few customers, the loss of any one or more of whom
  would have a materially adverse effect on the business of the
  Company.  The Company does business on a current basis and has
  no significant backlog of unfilled firm orders.



                                   - 2 -

<PAGE>
  Materials

      The Company purchases its aluminum ingot requirements from
  primary aluminum producers or spot metal brokers.  Although
  increased worldwide demand produces periods of tight supply of
  aluminum ingot and scrap, the Company has had satisfactory
  experience to date in obtaining sufficient raw materials to meet
  its requirements and does not anticipate material shortages which
  would significantly hamper its operations.

      Flat glass is purchased from domestic glass manufacturers.
  The Company has had satisfactory experience to date in obtaining
  sufficient glass to meet its requirements.

      The Company produces the aluminum extrusions used in the
  products it manufactures and sells.  Vinyl, wood, hardware,
  fasteners and screening are purchased from outside sources.


  Seasonality

      Sales of products designed for residential and commercial
  applications are subject to cyclical swings in new construction
  and seasonal fluctuations due to reduced construction activity
  in some marketing areas during the winter months (second and
  third quarters).


  Working Capital

      To maintain an adequate supply of aluminum to meet customer
  delivery requirements and to assure itself of a continuous
  allotment of materials from its suppliers, the Company at times
  carries a significant inventory of aluminum ingot.  Depending on
  price and availability, bulk quantities of ingot are purchased
  from either primary aluminum producers or from spot metal
  brokers.

      The Company does not believe there are any abnormal working
  capital requirements associated with any of its product groups
  as merchandise is normally produced for specific customer orders
  or shipped from inventory and as a general practice extended
  payment terms are not granted to customers.


  Patents

      The Company has no material patents, either issued or
  pending, and is not a party to any significant licensing
  agreements.

  Competition and Risk

      The business of International Aluminum is highly competitive.
  Competition in all product lines is on the basis of price,
  service and product quality.  The manner and extent of such
  competition depends on the product being marketed and the
  relevant marketing area.  In selling its residential products to
  mass merchandisers, dealers and distributors, the Company faces
  competition primarily from numerous fabricators.  Several of the
  Company's major competitors in selling commercial products and
  aluminum extrusions are substantially larger, more diversified
  and have greater resources than the Company.

      The Company anticipates that expansion of its product lines
  may result in its competing with certain of its present
  customers.  While the Company cannot accurately predict the
  effect, if any, that such development will have on its business,
  the Company anticipates no material adverse effect.

      Since a substantial portion of the Company's business is
  connected with residential and commercial building construction,
  any significant decrease in new or remodeling construction could
  adversely affect revenues.  Experience has shown that high
  interest rates for construction financing and residential
  mortgage and home improvement loans may adversely affect
  revenues.

  Environmental Controls

      The Company's domestic aluminum extrusion, anodizing,
  painting and manufacturing facilities are subject to water and
  air pollution control standards mandated by federal, state and
  local law.  While the Company anticipates no material capital
  expenditures to meet established environmental quality control
  standards, there can be no assurance that more stringent
  standards will not be established which might require such
  expenditures.

  Employees

      As of June 30, 1999, the Company had approximately 2,200
  full-time employees.

  d.    FINANCIAL INFORMATION ABOUT FOREIGN AND DOMESTIC OPERATIONS

      The information concerning income before taxes of foreign and
  domestic operations for fiscal years 1999, 1998 and 1997 is set
  forth in Note 10 to the consolidated financial statements
  included on page 14 of the Company's 1999 Annual Report
  incorporated herein by reference.  Other related information
  regarding foreign operations is not significant for disclosure.
