Environmental Statement

Oldcastle BuildingEnvelope™ is the leading supplier of architectural glass and aluminum glazing systems, including custom-engineered curtain wall and window wall, architectural windows, storefront systems, doors and skylights. It is Oldcastle BuildingEnvelope™'s policy to be environmentally friendly to the communities where we manufacture as well as the areas in which our products are installed and maintained. Oldcastle BuildingEnvelope™ has an active Waste Minimization Plan and is continually improving its operations to reduce waste and maximize efficiency.

PRODUCT

Olfactory - Not applicable. No odors or volatile organic compounds (VOC) are emitted by the finished product. Auditory - Product itself does not generate or emit any sounds. Noise reduction capabilities of installed product which includes glass or other infill product can vary dependent upon the infill material used. Visual - Storefronts, curtain walls, windows and skylights are a very good source of natural daylight. Energy efficiency can vary based upon system design and infill product used. Glass as an infill offers a wide range of performance capabilities in reflectivity, light transmission, shading coefficient, etc. Building Related Illnesses - No history of any problems or potential in this area. Energy Requirements - Minimal energy is required during the application of product. Product Maintenance - Maintenance procedures for either anodized or painted products are readily available from AAMA or Oldcastle BuildingEnvelope™.

MANUFACTURING PROCESS

Recycled Content - A percentage of the billet we use to produce extrusions have an 80% re-consumer recycled material content. When notified at the bid stage, we have the ability to produce a project utilizing 45%-75% preconsumer recycled material and document the process accordingly. Reusable Life - All aluminum components are reusable by reprocessing into secondary aluminum for extrusion or casting purposes. Any PVC components and acrylic skylight domes can be processed and reused in other PVC extrusions or cast into acrylic sheet, respectively. EPDM gasket materials have a secondary life in road or athletic surfaces. Glass products have the potential to be used in paving materials, road deflectors and reflective paints. Non-tempered glass has the potential to be re-fabricated for use as a sheet product.

ENVIRONMENTAL STATEMENT INTERNAL RECYCLING

Aluminum Extrusion - All scrap generated in the extrusion operation is recycled. Scrap in this operation is still considered prime and Oldcastle BuildingEnvelope™ has this material re-cast into log for use in the extrusion operation. PVC Extrusion - All scrap is ground and reused in other PVC extrusions. Anodizing - Sodium Hydroxide is recycled in a caustic recovery system and sulfuric acid is recovered in an acid repurification system. Water utilization is minimized by circulating to regressive rinse tanks. All water is ultimately cleaned, pH corrected with all solids removed by a filtration process. A by-product of the anodizing process is aluminum trihydrate which is provided to producers of industrial alum and is eventually used in water treatment plants. Paint - All solvents are reclaimed and internal paint mixing capabilities allows utilization of excess color formulations by reformulating to a new color. Chrome, which is specified by AAMA in the pretreatment process, is captured and delivered to an outside agency for proper handling. Fabrication - All aluminum scrap including saw chips are captured and sold to recycling companies. Acrylic waste are either reformed into acceptable domes or sold for recycling. Wooden pallets are either reused or recycled. Cardboard, steel banding, polycarbonate and fiberglass are all recycled. Other - All miscellaneous metals such as steel and copper are recycled. Other recycled items include beverage cans, printer cartridges and florescent bulbs.

NON-POLLUTING

All heat requirements are satisfied by natural gas or electricity. In the anodizing process, all chemicals are either reclaimed and recycled, such as sodium hydroxide and sulfuric acid already mentioned, or captured and sent to a proper reclamation or processing company. Paints are applied with electrostatic equipment to reduce over spray which is captured in a thermal oxidizer providing 98% or greater destruction of volatile organic compounds (VOC). Oldcastle BuildingEnvelope™ makes every effort and to the best of our knowledge is 100% compliant with all local, state or federal environmental requirements. A staff specialist is devoted to environmental concerns and compliance. Also, Oldcastle BuildingEnvelope™ has conducted hazardous materials training to minimize risk to all employees and environmental damage. Energy Efficiency - Our goal is to conserve energy. Ovens insulated to the best possible degree and seal tanks in anodizing are covered for heat retention and energy conservation. Premium efficiency motors are utilized on equipment such as compressors, pumps and chillers. Most plant areas utilize skylights for natural lighting and reduction of electrical lighting. All new and replacement lighting uses electronic ballasts and high efficiency lamps. Occupancy sensors for lighting are used in all new and remodeled offices. New and replacement HVAC systems utilize the high-energy efficiency designs. 06/08
