Low-Iron Float Glass

Ultra Clear for Maximum Light Transmittance

Cardinal’s low-iron float glass yields a higher solar transmittance in comparison to standard clear float allowing for enhanced visual clarity. Low-iron glass is formulated to be crystal clear and virtually tint-free. It is produced utilizing Cardinal’s world-class manufacturing processes and I.Q. quality assurance systems.

Low-iron glass can have as little as 10% of the iron content of regular glass, allowing it to transmit 91% of light, compared to 83-85% for regular glass and without the greening effect that is in thicker regular glass panes.

So Clear, It’s Almost Transparent

What makes low-iron glass so luminous? We design it for exceptional clarity by using a special formula that includes reducing iron. The result increases light transmission, along with brilliant clarity, providing an exceptional glass that can be used in place of regular glass for interior and exterior uses. With Cardinal’s low-iron solar glass, nothing is obstructed. The view is clean and clear, no matter the application.
