This older 3M Crystalline 40 article has been consolidated into the current CR40 technical guide.

Use the updated 3M Crystalline 40 (CR40) VLT, TSER and performance guide for the primary explanation of visible-light transmission, total solar energy rejected, UV performance, infrared metrics, factory glass and shade selection.

The current guide uses product-data context rather than unsupported fixed pricing, blanket legality statements or unverified “real-world testing” claims.
