Help find good reflectivity Lighting Sheets

Who makes very good reflectivity lighting sheet and where can I get specs and stock? I need it for thermal radiation shielding for The Navy Prototype Interferometer, a field of optical telescopes with an apparent aperture of 500 meters.

Two manufacturers of preanodized coil which offer high reflectivity are Lorin Industries, Muskegon, MI and Aluminum Coil Anodizers in Streamwood, IL. If you are looking for unanodized sheet they may be able to refer you to their suppliers or sell it to you.
