Additional Glass Options – For even higher performance, Milgard offers these door and window glass options.
- Tempered – Tempered glass is extremely strong and often used for its safety characteristics. Not only is it extra strong, but when it breaks, it breaks into little pebble-like pieces without sharp edges. Tempered glass is ideal for reducing the likelihood of injury in the event of breakage in applications like patio doors, side lights and bathroom enclosures for showers and tubs.
- Laminated – Laminated glass is highly effective in reducing noise. It also eliminates 99.9% of ultraviolet rays, providing the highest degree of protection from the sun for your home furnishings. Concerned about excessive outdoor noise? Get the utmost protection against noise with our Sound Control Windows.
- Argon/Air Mix – Optional argon gas, used between panes, is also available to further improve thermal performance.
